Dishwasher symbols can seem confusing when you are faced with unfamiliar icons on the control panel, detergent compartment, or the bottom of a plate or container. A small symbol can tell you whether a dishwasher is washing, rinsing, drying, using an intensive cycle, or asking you to refill salt or rinse aid.
The important thing to remember is that dishwasher symbols are not completely universal. Some functions have widely recognized icons, while manufacturers can use different symbols for programs and features. AEG, for example, notes that indicators and programs can vary between dishwasher models.
This guide explains the most common dishwasher symbols, what they look like, what they mean, and what you should do when an indicator appears.
Dishwasher Symbols at a Glance
Here is a quick reference for the most common dishwasher symbols:
| Symbol or appearance | Common meaning | What it tells you |
| Eco / leaf-like icon | Eco wash | Uses an efficiency-focused program |
| Pot or pan | Intensive wash | For heavily soiled cookware |
| Auto | Automatic wash | Adjusts the cycle automatically |
| Glass | Glass/delicate | For suitable delicate glassware |
| Stopwatch/clock | Quick or timed cycle | Shorter or scheduled washing |
| Water drops | Rinse/pre-rinse | Rinsing or pre-rinsing |
| Wavy lines | Drying | Drying phase or drying option |
| Star/sparkle | Rinse aid | Rinse-aid refill indicator |
| S-shaped arrows | Dishwasher salt | Salt needs replenishing |
| Faucet/tap | Water supply | Check the water connection |
| Key/lock | Child lock | Controls are locked |
| Brush | Washing | Cleaning phase is running |
| Half-load icon | Half load | Smaller load option |
| Sparkle/extra-dry icon | Extra Dry | Enhanced drying |
| Plates under water drops | Dishwasher safe | Item is intended for dishwasher cleaning |
| Hand in water | Hand wash | Wash the item by hand |
The exact icon can look different from one manufacturer or model to another.
What Do Dishwasher Symbols Mean?
Dishwasher symbols generally fall into four groups:
- Wash-program symbols — tell you which cycle you are selecting.
- Option symbols — add features such as extra drying or half load.
- Status and warning symbols — tell you what the machine is doing or whether it needs attention.
- Tableware symbols — appear on dishes, glasses, cookware, and containers to explain care instructions.
Knowing which category a symbol belongs to makes it much easier to understand.
Common Dishwasher Cycle Symbols
Eco Symbol
The Eco symbol identifies an energy- and water-efficient washing program.
An Eco program can take longer than a quick or standard cycle. The longer duration is intentional: the dishwasher can clean normally soiled dishes while using resources efficiently. Bosch describes its Eco program as a longer cycle that uses less water and electricity.
Best for: Normally soiled plates, cups, cutlery, and cookware.
Remember: Eco does not necessarily mean the fastest program. It is designed around efficiency rather than speed.
Auto Symbol
The Auto or AutoSense symbol represents an automatic washing program.
On compatible models, sensors can help determine appropriate washing conditions based on the load and how dirty the dishes are. AEG describes AutoSense as using sensors to tailor settings to the load.
Best for: Mixed loads when you are unsure which standard cycle to choose.
Intensive or Heavy Wash Symbol
A pot, pan, or heavily soiled cookware icon commonly represents an intensive program.
Intensive cycles generally use stronger spray pressure and higher temperatures. Bosch’s Intensive 70°C program, for example, is intended for stubborn, burned, or dried-on food residue.
Best for:
- Pots
- Pans
- Baking dishes
- Heavily soiled cookware
- Dishes with dried-on food
Always check whether your cookware is dishwasher-safe before using a high-temperature cycle.
Glass or Delicate Symbol
A wine glass or glassware icon usually represents a delicate or glassware program.
These programs are designed for suitable sensitive glassware and may use gentler temperatures or washing conditions. Bosch’s Glass 40°C program, for example, is designed for sensitive glass items.
Best for: Dishwasher-safe glasses and delicate tableware.
Quick or Express Wash Symbol
A stopwatch or clock-like symbol can indicate a quick, express, or short-duration program.
These programs are useful when you need clean dishes quickly, although the exact cleaning and drying performance depends on the model.
Some Bosch models, for example, have Express programs specifically designed to wash dishes or glasses more quickly.
Best for: Lightly or normally soiled dishes when saving time is important.
Pre-Rinse or Rinse Symbol
A symbol showing water drops, a spray, or dishes being rinsed can indicate a rinse or pre-rinse function.
A pre-rinse can be useful when dishes have been sitting for some time or when you want to rinse food residue before running a complete program. AEG describes its pre-wash program as a quick rinse intended to remove food residue and prevent odors when a full program is not being started immediately.
Important: A pre-rinse program may not require detergent. Follow your model’s instructions.
Dishwasher Option Symbols
Some symbols do not represent complete washing programs. Instead, they modify the selected program.
Half-Load Symbol
The half-load symbol usually represents a smaller load option.
It is useful when you do not have enough dishes to fill the dishwasher. Depending on the model, the machine may adjust water, energy, time, or the washing area.
Bosch, for example, describes its Half Load option as being designed for smaller quantities of dishes and intended to save resources.
Best for: A partially filled dishwasher when your model specifically supports the feature.
Delay Start or Timer Symbol
A clock or timer symbol commonly represents delayed start.
It allows you to schedule the dishwasher to begin or finish later, depending on the model.
For example, some Bosch dishwashers offer timer settings for different completion times.
Useful when: You want to run the dishwasher later rather than immediately.
Extra Dry Symbol
An extra-dry symbol may use wavy lines, heat waves, or another drying-related icon.
The Extra Dry option increases drying performance. Bosch describes its Extra Dry function as using higher temperatures during the rinse stage and a longer drying phase.
Best for: Plastic containers, cups, and other items that tend to retain water.
Hygiene or Hygiene+ Symbol
Some dishwashers have a Hygiene or Hygiene+ option.
This function can increase the temperature of the final rinse for a more hygienic wash. Bosch, for example, describes Hygiene+ as using an extra-hot final rinse and identifies uses such as chopping boards and baby bottles.
Always follow the care instructions for the particular items being washed.
IntensiveZone Symbol
Some advanced dishwashers have an IntensiveZone option.
It is designed to provide stronger washing conditions in a particular basket or zone, allowing heavily soiled cookware to be washed while more delicate items remain in another area.
Bosch describes IntensiveZone as increasing spray pressure and temperature in the lower basket on compatible machines.
Dishwasher Status Symbols
Status symbols tell you what the dishwasher is currently doing.
Brush Symbol
A brush-shaped icon can indicate that the dishwasher is actively washing or cleaning.
On Bosch models, the brush symbol means the machine is cleaning the dishes.
You normally do not need to take action when this symbol is displayed.
Rinsing Symbol
A water-spray or shower-like symbol can indicate the rinsing phase.
The dishwasher has moved beyond the main washing stage and is rinsing the dishes.
AEG lists a dedicated rinsing-phase indicator on compatible models.
Drying Symbol
A wavy-line or heat-related symbol may indicate that the dishwasher is drying the dishes.
The symbol can appear while the drying phase is active or when a drying option has been selected.
AEG identifies a drying-phase indicator that can flash while drying is taking place.
Machine Care Symbol
Some modern dishwashers include a Machine Care or self-cleaning program.
This is intended to clean the dishwasher itself rather than simply wash dishes.
Bosch explains that its Machine Care program can help clean the appliance and reduce the buildup of grease, limescale, and odors when used according to the manufacturer’s instructions.
Dishwasher Warning Symbols
Warning symbols deserve particular attention because they may indicate that the dishwasher needs something from you.
Rinse Aid Symbol
The rinse-aid symbol often looks like a star, sparkle, or sun with small rays or dots.
If this indicator lights up, the rinse-aid reservoir usually needs to be refilled.
Rinse aid helps water run off dishes more effectively during the final rinse, improving drying and reducing water marks.
What to do: Open the rinse-aid dispenser and refill it with the appropriate dishwasher rinse aid according to your manual.
Dishwasher Salt Symbol
The dishwasher salt symbol commonly looks like an S or two curved arrows forming an S-like shape.
It indicates that the dishwasher salt reservoir needs attention.
Dishwasher salt is used by compatible machines to soften hard water and help reduce limescale buildup.
What to do: Refill the dishwasher salt reservoir with purpose-made dishwasher salt if your dishwasher uses a salt-softening system.
Do not automatically substitute ordinary table salt. Follow the manufacturer’s instructions.
Tap or Faucet Symbol
The tap/faucet symbol generally indicates a water-supply or water-inlet problem.
Possible causes include:
- The water tap is closed.
- The inlet hose is kinked.
- A hose or filter is blocked.
- The dishwasher is not receiving enough water.
- There is another water-inlet or appliance problem.
Bosch recommends checking the water connection and hoses when its tap symbol appears.
What to do:
- Check that the water supply is turned on.
- Inspect the inlet hose for kinks.
- Check accessible filters or connections according to the manual.
- Restart the dishwasher if the manufacturer’s instructions allow it.
- Contact service if the warning remains.
Do not dismantle water or electrical components unless you are qualified to do so.
Child Lock Symbol
A key or padlock icon generally indicates that the child-lock function is active.
The controls may not respond normally while the lock is enabled.
The method for activating or disabling it varies by model, so use the manufacturer’s instructions rather than trying random button combinations.
Dishwasher Detergent Symbols
The detergent symbol is usually found inside the dishwasher door near the detergent dispenser.
Main Wash Detergent Symbol
The main-wash detergent symbol commonly resembles stylized lines or something being sprayed or showered.
It identifies the compartment intended for dishwasher detergent. CHOICE describes this commonly used symbol as a standardized main-wash detergent indication.
Depending on the dishwasher, you may use:
- Dishwasher tablets
- Dishwasher pods
- Dishwasher powder
- Dishwasher detergent gel
Always follow the dishwasher and detergent manufacturer’s directions.
Dishwasher-Safe Symbols on Plates and Containers
The phrase dishwasher symbols can also refer to symbols printed or stamped on dishes, glasses, cookware, and food containers.
These symbols answer a different question:
Can this item safely go into the dishwasher?
Is There One Universal Dishwasher-Safe Symbol?
No. There is no single universally recognized dishwasher-safe symbol.
Different manufacturers use different designs. Whirlpool explains that several symbols can indicate dishwasher suitability, including designs showing dishes or glasses being exposed to water.
This distinction is important because people often search for “the dishwasher-safe symbol” as though there is only one official icon.
Dishwasher-Safe Symbol: Glass With Water Drops
One common design shows a glass or wine glass with water droplets falling onto it.
This generally indicates that the item is intended to be dishwasher-safe.
Dishwasher-Safe Symbol: Plates Under Water
Another common design shows one or more plates inside a dishwasher-like box with water droplets or spray above them.
This is another commonly used dishwasher-safe marking. Whirlpool and Bosch both show variations of this type of symbol.
Dishwasher-Safe Symbol: Single Dish With Water Drops
Some products show a single plate or dish with water droplets falling onto it.
Again, the precise design varies by manufacturer.
Top-Rack-Only Symbol
A dishwasher-safe symbol may include wording such as “Top Rack Only.”
This means the item should be placed on the dishwasher’s upper rack rather than the bottom rack.
The reason is that the upper rack can be farther from the heating element or other intense heat sources in some dishwasher designs. Maytag and Finish both explain the significance of top-rack-only markings.
This marking is particularly common on some plastic items.
Dishwasher-Proof Symbol
A dishwasher-proof symbol is not exactly the same as an ordinary dishwasher-safe marking.
Bosch explains that the term “dishwasher proof” applies to tableware and utensils certified under EN 12875, with a number indicating how many dishwasher cycles the item can withstand without damage.
For example, a dishwasher-proof symbol containing 500 can indicate resistance to 500 dishwasher cycles under the applicable test conditions.
This is different from simply seeing a general dishwasher-safe marking.
Hand-Wash Symbol
A hand with water is generally associated with hand washing.
If an item carries a clear hand-wash instruction, it should not automatically be placed in the dishwasher.
This is particularly important for:
- Delicate glassware
- Certain wooden items
- Hand-painted ceramics
- Some insulated containers
- Certain nonstick cookware
- Items with sensitive finishes
When in doubt, follow the product manufacturer’s care instructions.
Food-Safe Symbol vs. Dishwasher-Safe Symbol
These symbols are easy to confuse.
Food-Safe Symbol
The fork and wine-glass symbol indicates that a material is intended for contact with food.
It does not mean that the item is dishwasher-safe.
Bosch identifies the stylized fork-and-wine-glass icon as the international food-contact symbol.
Dishwasher-Safe Symbol
A dishwasher-safe symbol indicates that the item is intended to withstand dishwasher cleaning according to the manufacturer’s specifications.
Therefore:
Food safe ≠ dishwasher safe.
An item can be safe for food contact while still requiring hand washing.
Dishwasher Symbols by Material
Understanding the symbol is only part of the equation. The material also matters.
Plastic
Check for a dishwasher-safe marking and any top-rack-only instruction.
Some plastics can deform or deteriorate under high heat, so do not assume every plastic container is dishwasher-safe.
Glass
Many everyday glasses are dishwasher-safe, but delicate crystal or specialty glassware may require a gentler program.
Use the manufacturer’s instructions and the appropriate glassware cycle when available.
Stainless Steel
Many stainless-steel utensils and cookware products are dishwasher-safe, but special coatings, finishes, handles, or attached components can change the care requirements.
Wood
Wooden cutting boards, utensils, and other wooden products often require special care.
Do not put them in the dishwasher simply because another item made from a similar material is dishwasher-safe.
Nonstick Cookware
Check the manufacturer’s instructions before putting nonstick pans in the dishwasher.
Even when an item is technically dishwasher-safe, repeated exposure to detergent, heat, and water can affect its finish over time.
What to Do When a Dishwasher Symbol Is Flashing
A flashing symbol does not always mean the same thing on every dishwasher.
Use this general approach:
If the Salt Symbol Is Flashing
Check the dishwasher salt reservoir and refill it if necessary.
If the Rinse-Aid Symbol Is Flashing
Check the rinse-aid dispenser and refill it according to the manufacturer’s instructions.
If the Tap Symbol Is Flashing
Check:
- Water supply
- Tap position
- Inlet hose
- Accessible filters
- Connections
If the problem continues, consult the manual or contact an authorized service provider.
If the Lock Symbol Is Showing
The child lock may be active.
Look in the manual for the correct procedure to disable it.
If You See an Unknown Warning
Do not assume what it means from the appearance alone.
Take note of:
- The exact symbol
- Whether it is steady or flashing
- Any error code on the display
- What the dishwasher is doing
- Your dishwasher’s brand and model
Then check the manufacturer’s documentation.
Why Dishwasher Symbols Are Different Between Brands
There is no guarantee that the same-looking symbol means exactly the same thing on every dishwasher.
For example, Bosch provides symbols for functions such as Eco, Auto, Intensive, Machine Care, Hygiene+, IntensiveZone, Extra Dry, and Half Load. AEG also has its own collection of program and status indicators.
Older models can also use different versions of symbols from newer models.
Bosch Dishwasher Symbols
Bosch commonly provides symbols for:
- Eco
- Auto
- Express
- Glass
- Intensive
- Machine Care
- Hygiene+
- IntensiveZone
- Extra Dry
- Half Load
- Timer
- Rinse aid
- Salt
- Tap/water supply
- Washing
- Rinsing
- Drying
- Child lock
AEG Dishwasher Symbols
AEG notes that its models can have different indicators and programs. Its documented examples include salt, rinse aid, cleaning, rinsing, drying, pre-wash, Eco, and Auto/AutoSense symbols.
For any brand, the exact model manual is the final authority.
How to Identify an Unknown Dishwasher Symbol
If you see a symbol you do not recognize, use these steps.
Step 1: Check Where the Symbol Appears
Is it:
- On the control panel?
- Inside the detergent compartment?
- On the display?
- On the bottom of a plate?
- On a plastic container?
Its location can immediately narrow down its meaning.
Step 2: Check Whether It Is Lit or Printed
A permanently printed icon may identify a button or compartment.
A light that appears during operation may be a status or warning indicator.
Step 3: Look for Nearby Numbers
A temperature such as 40°C, 50°C, 60°C, or 70°C can help identify a wash program.
Step 4: Check the Manual
Search for the exact dishwasher model rather than simply searching for the brand.
This matters because the same brand can use different symbols across different models.
Step 5: Check Whether the Symbol Is Flashing
A flashing indicator may represent a warning or a current phase rather than a selectable program.
Common Dishwasher Symbol Mistakes
Mistaking the Salt Symbol for a Warning of a Broken Dishwasher
The salt indicator normally means the salt reservoir needs attention. It does not automatically mean the dishwasher is broken.
Assuming a Star Means “Favorite”
A star or sparkle can have different meanings depending on the location and model. On many dishwashers it is associated with rinse aid, while some smart dishwasher systems may use a star for a favorite function.
Always consider the context.
Confusing Food Safe With Dishwasher Safe
The fork-and-glass symbol means food contact suitability, not necessarily dishwasher compatibility.
Assuming Every Plastic Container Is Dishwasher-Safe
Plastic should be checked individually. Look for the manufacturer’s dishwasher-care instructions and any top-rack-only warning.
Assuming Dishwasher-Safe Means Indestructible
“Dishwasher safe” does not necessarily mean an item will remain unchanged forever. Bosch notes that dishwasher-safe labeling does not rule out long-term effects such as discoloration.
Dishwasher Symbols vs. Dishwasher-Safe Symbols
Although the terms sound similar, they refer to different things.
| Feature | Dishwasher Symbols | Dishwasher-Safe Symbols |
| Found on | Dishwasher | Plates, cookware, containers |
| Main purpose | Explain machine functions | Explain item-care instructions |
| Examples | Eco, Auto, Intensive | Dishwasher-safe, top rack |
| Can indicate a warning? | Yes | Usually no |
| Manufacturer differences | Common | Common |
| Best reference | Dishwasher manual | Product manufacturer’s instructions |

Final Thoughts
Understanding dishwasher symbols makes everyday dishwasher use much easier. The most important icons to recognize include Eco, Auto, Intensive, Glass, Quick, Pre-Rinse, Half Load, Extra Dry, rinse aid, dishwasher salt, tap, child lock, washing, rinsing, and drying.
You should also know the difference between symbols on the dishwasher and symbols printed on tableware. A dishwasher control-panel icon tells you what the appliance is doing or which function you have selected, while a dishwasher-safe symbol on a plate or container provides information about how that item should be cleaned.
Most importantly, remember that there is no single universal dishwasher-safe symbol, and dishwasher programs can vary between brands and models. When an unfamiliar symbol appears—especially a warning or flashing indicator—the manufacturer’s manual for your exact model is the most reliable source.
