Dishwasher does not start.
Dishwasher may not start due to the following reasons:
Door may not be properly latched. Shut the door completely until you hear a click.
Dishwasher may not be turned on. Press the main power switch to turn it on.
Previous wash cycle may be interrupted. Reset the dishwasher to cancel the previously chosen cycle according to the instructions in the Use & Care Guide.
“Delay Start” or “Control Lock” may be activated. Deactivate the “Delay Start” or “Control Lock”. Please refer to the Use & Care Guide to learn how to do this.
The circuit breaker and/or water supply may not be on. Check to make sure both are on. The dishwasher water supply is typically located under the sink. Reset the circuit breaker if necessary.
Door may have been closed without selecting a cycle. Please select a wash cycle and ensure the door is closed completely.
Dishwasher display does not light up.
This may be due to the following reasons:
The Power Switch may not be switched on. Push the Power Switch.
For models with controls on the top portion of the door: The display only illuminates when the door is opened and controls are visible.
For models with the controls on the face of the dishwasher: Some models have a display that only illuminates when the door is closed.
Default factory settings on the dishwasher beep when a dishwashing cycle has finished. This feature can be deactivated if desired. To deactivate this feature or adjust the volume, consult your Use & Care Guide.
Dishwasher seems to run a long time.
This can occur due to the following reasons:
Incoming water is not warm enough.
If the incoming water is not hot enough, the dishwasher will extend the wash cycle to heat the water internally in the dishwasher’s heat pump.
TO reduce wash time, briefly run hot water faucet at the sink closest to the dishwasher prior to starting the dishwasher.
Sensors in the dishwasher extend cycle time to wash off heavy food soils.
Rinse aid dispenser is empty.
The dishwasher extends cycle time to compensate for lack of rinse aid by adding a longer final rinse.
Add rinse aid to avoid this.
Dishwasher is connected to a cold water supply.
The wash cycle is extended to heat the water internally in the dishwasher’s heat pump.
Connect the dishwasher to a hot water source to reduce run time.
Dishwasher contains a lot of odors.
Odors can occur in the dishwasher due to the following reasons:
Food debris in the bottom of the dishwasher.
Remove the filters and clean according to the “Care and Maintenance Section” of the Use & Care Guide. Also, view our Bosch How-to-Videos to learn how to clean the dishwasher filter.
Food particles near the door seal.
Wipe with a damp cloth. Dry with a soft cloth.
Residual water at the bottom of the dishwasher.
Ensure the unit has completely drained from the last cycle.
Activate the drain. Please refer to the Use & Care Guide to learn how to do this.
Drain hose is obstructed.
Ensure the drain hose isn’t kinked.
Remove any obstructions from the drain hose (contact a qualified personnel to do this).
Ensure the drain hose high loop is between 20” and 50” above the ground.
If odor still persists, run the Normal/Regular cycle and after 10 minutes open the door and place an 8 oz. cup of distilled vinegar solution on the top rack and close the door to finish the cycle.
Dishwasher is not filling with water.
This may be due to any of the reasons below:
The previous wash cycle may not have completed before unloading your items. To complete the cycle, reset the dishwasher according to the instructions in the Use & Care Guide
Restriction in the water supply
Check that the water supply valve is open. It is typically located under the kitchen sink.
Check and ensure that the water supply line has no kinks or clogs.
Shut off the supply, disconnect the hose, flush the line by passing two gallons of water through the line.
Check and ensure the household water supply is not turned off.
Delay start is active. Cancel delay start or wait until delay is complete.
Water is leaking from the door.
Water leakage may be caused by the following:
Incorrect detergent may have been used – Use automatic dishwasher detergents - do not use dish detergents. If suds persist, add one tablespoon of vegetable oil to the bottom of the dishwasher and run the desired cycle.
Door seal could have pulled away. The door seal may have been caught on dishes that extend beyond the sides of the dishwasher rack. Push the seal back into place (located on the inside edge of the dishwasher).
Condensation vent may be blocked. This can occur if flexible cutting boards or cookie sheets block the condensation vent (gray circular vent, on the side center of the dishwasher), thus causing the dishwasher to leak from the door instead of venting properly via the condensation vent. Remove anything that is blocking the condensation vent and load flexible boards or sheets on the top rack.
Dishwasher may have been improperly installed. The dishwasher “feet” must be leveled properly. If not, gaps at the top of the dishwasher door may occur. In this case, adjust the “feet” accordingly. Please also have the installation verified by qualified personnel. They should check the water supply, drainage, leveling and plumbing.
Streaks on glassware or dishes.
Reduce the amount of rinse aid that is dispensed during the wash cycle. Please refer to the “Adding Detergent and Rinse Aid” section of the Use & Care Guide to learn how to do this.
Dishware is not thoroughly cleaned at end of cycle.
Please check the following to ensure your dishwasher is washing effectively:
Spray arm movement may be obstructed – ensure the spray arm is not blocked by manually spinning each spray arm. It should rotate freely.
Spray arm nozzles may be clogged – remove the spray arms and clean according to the “Care and Maintenance” section of the Use & Care Manual. Also, view our Bosch How-to-Videos to learn how to clean a dishwasher spray arm.
Improper use of detergents – increase or decrease the amount of detergent depending on water hardness and food debris. Please refer to the Use & Care Manual for more information.
Filters could be clogged – clean the dishwasher filter according to the “Care and Maintence” section of the Use & Care Manual. Also, view our Bosch How-to-Videos to learn how to clean the dishwasher filter.
Dishes are nested or loaded too close together – Rearrange your dishware so that water spray from the spray arms can reach all items in the dishwasher. See the “Loading the Dishwasher” section of the Use & Care Manual. Also, view our Bosch How-to-Videos to learn how to load a dishwasher.
Wash cycle is unsuitable for the level of food debris – select the correct wash cycle for your dish load. Refer to the “Wash Cycle Information” section of the Use & Care Manual to learn how to select the right cycle.
Dishwasher dries poorly.
Plastic items do not dry as completely as other items.
Check your rinse aid setting and adjust up. Read your Use & Care Guide to see how to adjust the rinse aid setting.
You may have chosen a short cycle like “Quick”. Most short cycles like “Quick” do not have a drying cycle so everything will be damp.
Always empty the lower rack first since the upper spray arm will still have some water left in it. This extra water may drip onto items in the lower rack.
Select models have an Extra Dry Option. Instructions for how to activate this are in the Use & Care Guide. This adds extra heat to the final rinse and will enhance drying results.
Select models have a Sanitize Option. Instructions for how to activate this are in the Use & Care Guide. This raises the final rinse time and temperature to achieve standards set by NSF (National Sanitation Foundation) for sanitization in residential dishwashers.
Dishwasher won't drain.
First, check the drain lines for blockages in the garbage disposal and air gap. After clearing the blockage, select the “Cancel/Drain” Program.
Drain pump may be blocked by debris. Empty the water from inside the dishwasher using a ladle or something similar. Consult the Use & Care Guide to learn how to unblock the drain pump. In the future, scrape dishes of large debris before putting into the dishwasher.
The dishwasher’s filters may not be clean. Remove the filters and clean them. To clean the filter: Remove the dishwasher filter carefully. It is located at the bottom of the dishwasher. Rinse the filter and its components under lukewarm water. Gently use a scrub brush to remove particles. Rinse and dry with a soft cloth. View our Bosch How-to-Videos to learn how to clean the dishwasher filter.
Drain hose must have a “high loop” between 20” and 50” above the floor to pump properly. Consult the installation instructions for more details.
If drain extension is used, ensure the max length of the drain hose, including the hose leading to air gap is no more than 150”.

How long does it take for a cycle to finish?
The dishwasher analyzes many aspects of dishwashing while running. It analyzes the water temperature, cycle chosen, and the soil level in the water when deciding how long to run for.
Water at the bottom of the dishwasher.
A small amount of water around the filter is normal and nothing to be alarmed about.
Do I need to pre-rinse items before loading them into the dishwasher?
No. Just scrape food, bones and other heavy debris off the dishes and put dishes into the dishwasher. Dishwasher detergents contain enzymes, which find food particles and break them down. If there is no food to cling to, the enzymes could damage your dishware resulting in etched or cloudy glasses and dishes over time. Pre-rinsing dishes under running water also wastes a large amount of water per year.
How to load a dishwasher.
View our How-to-Videos on the Bosch YouTube Channel to learn how to load your dishwasher.
- Pre-rinsing: Just scrape food, bones and other heavy debris off the dishes and put dishes into the dishwasher. Dishwasher detergents contain enzymes, which find food particles, digest them and wash them away. If there is no food to cling to, the enzymes could damage your dishware resulting in etched or cloudy glasses and dishes over time. Pre-rinsing dishes under running water wastes a large amount of water per year.
- Silverware: Knives should be put into the cutlery basket with the blade facing downwards for safety reasons. Forks and spoons can be put into the cutlery basket with the top of the utensil facing up or down - mix it up so that spoons and forks don’t nest into each other as this could result in less efficient cleaning.
- Dishes: On the left side of the dishwasher, load dishes so they face inwards towards the center. On the right side of the dishwasher, load dishes to they face inwards towards the center.
- Bowls: Place bowls on their side for maximum exposure to water flow. Do not place bowls facing completely downwards as this limits their exposure to water flow.
- Large pans & platters: Place these items along the outer sides of the lower rack
- Stemware & cups: Load these on an angle to limit the amount of standing water after the wash cycle is complete. Loading on angle allows water to slide off the cups.
- Plastics: Plastic items can be placed on the upper or lower rack because Bosch dishwashers do not contain a heating element at the bottom of the dishwasher.
What is condensation drying?
All Bosch dishwashers use the condensation drying process to dry items in the dishwasher. Condensation drying does not utilize a heating element at the bottom of a dishwasher. Instead, it involves a number of dishwashing elements that result in an energy efficient, high-quality drying process:
- The final rinse uses water that has been heated to a very high temperature.
- This makes the dishware very hot when the rinse cycle ends.
- The stainless steel tub of the dishwasher cools faster than the dishware because stainless steel typically cools faster than dishware materials (such as glass and porcelain).
- Condensation occurs when the moist air in the dishwasher comes into contact with the cooler stainless steel tub and turns into water droplets. These water droplets trickle down to the bottom of the dishwasher and are drained.
- Dishware and cups become dry during this condensation process. Plastics tend to have more difficulty drying because plastic does not heat up to a high temperature during the final rinse like glass/porcelain does.
The use of rinse agents, such as Jet Dry®, aids the condensation drying process by reducing the surface tension of water, thus encouraging water to run off dishware effortlessly. We have extensive experience with Jet Dry® and Jet Dry® Turbo Dry® and highly recommend either product to help create an optimal drying experience that reduces the chance of spots and other leftover residue. Approximately 3.5 drops of rinse agent is dispensed during each wash cycle. Use Jet Dry® for your regular drying needs. Use Turbo Dry® if you are drying a lot of plastic in the dishwasher or if you are already using a detergent with a rinse aid included in it and it’s still not drying adequately.
The cycle time on my dishwasher adjusts in the middle of a wash cycle.
This is normal and does not indicate a problem. The Bosch dishwasher performs an AquaSensor check on the level of dirt in the water during the wash cycle to achieve the best energy consumption rates. For example, if the dishes are not very dirty, the water will not need to heat as long and the cycle time will shorten automatically. On the other hand, if the level of dirt in the water is high, the dishwasher will increase cycle time to clean your dishware thoroughly.
There is some water in my brand new dishwasher.
This is normal and nothing to be alarmed about. Each dishwasher we build is tested in the factory before it leaves for the store. The water you see is from that testing. This is perfectly normal and does not affect operation.
Glasses have cloudy appearance.
There are two primary reasons – white film from hard water and etching. Wash the glass in a bowl of vinegar, if the cloudiness disappears then the cloudiness was caused by hard water. If the cloudiness does not disappear, it was caused by etching. Explanations and solutions for both are explained below:
White film from hard water:
Adjust the amount of detergent used in the dishwasher. The amount may vary so some experimentation may be needed depending on the level of water hardness.
Increase the amount of rinse aid that’s dispensed during the wash cycle. Please refer to the Use & Care Manual to learn how to do this.
Utilize water softener in your dishwasher. This only applies to dishwasher models that contain a water softener. Please refer to the Use & Care Manual to learn how to add water softener or view our Bosch How-to-Videos to learn how to add salt to the dishwasher.
Etching is caused by glass surface erosion from heat exposure and contact with acidic solutions. It is permanent.
Etching can possibly be prevented by not pre-rinsing or pre-washing dishware, using a light wash cycle for glasses and using the correct amount of detergent (not more than needed).
The remaining time on my dishwasher adjusts in the middle of the wash cycle.
The dishwasher uses sensors to detect the amount of soil in the wash water and adjusts wash conditions based on this information to ensure a proper wash is achieved. The time remaining on the display changes accordingly while the wash cycle is occurring.
