You won’t have to worry about dirty dishes or handwashing ever again once you follow our troubleshooting steps. But, your life is about more than just cleaning up after yourself – let us take care of the dirty work while you focus on the important stuff!

1. Dishwasher Will Not Start


  • The door may be improperly latched.
  • The power for the dishwasher may have been turned off.
  • The unit has not been reset, or the previous cycle has not been completed.
  • The start delay has been activated.
  • Dishwasher not responding to power outage or a blown fuse.
  • The door may have been shut without first choosing a cycle.
  • There may be no water available to turn on.


  1. Shut the door all the way.
  2. To turn the device on, press the main power switch.
  3. To reset, refer to “Cancel a Cycle” in this guide.
  4. To reset, refer to “Delay Start” in this guide’s “Wash Cycles and Options” section.
  5. Check the circuit breaker to make sure whether it is on or off.
  6. Close the door and select a cycle.
  7. Check that the water is turned on and that the sink is free of debris.

2. Display Does Not Illuminate


  • A fuse may have been blown, or a circuit breaker tripped
  • Door not closed or latched


  1. If the circuit is still not working, check the fuse box or circuit breaker box for a blown fuse or resetting the breaker.
  2. Make sure the door is latched and shut correctly.

3. Dishwasher Seems To Run a Long Time


  • The water is not hot enough to bathe in.
  • Because of the conditions of the ground and water, cycle time is unpredictable.
  • The rinse agent dispenser is empty.
  • Cold-water supply connected to a dishwasher The following is a list of typical cycle lengths provided in this manual’s “wash cycle information” section.


Before beginning a cycle, run the hot water tap at the sink closest to the dishwasher. When sensors in the dishwasher detect heavy soil, the cycle time is automatically prolonged to ensure a good wash. Add rinse agent.

4. Dishes Are Not Getting Clean Enough


  • In some cases, your spray arm may be restricted by an obstruction.
  • Spray nozzles got clogged
  • Detergents are misused.
  • Filters might become clogged.
  • Dishes are stacked too closely or nested.
  • Food soil cannot be adequately washed in the selected wash cycle.


Before starting the washer, make sure hand-rotating spray arms aren’t blocking the spray arm. Then, remove the spray arms and clean them as directed in the “Care and Maintenance” section. Detergent should be increased or decreased depending on water hardness levels. Cleaning any filters is a good idea while they’re still wet.

5. Dishes Are Not Getting Dry Enough


  • The rinse agent dispenser is empty.
  • Dishes were loaded incorrectly
  • Drying is not included in the selected cycle.

Note: Due to their qualities, polyethylene or Teflon do not dry as well as other items.


Using a rinse agent improves drying. Rearrange the load to make sure objects aren’t nested. Rinse and Hold does not include a drying function. Select models have an extra heating option to enhance drying performance.

6. Odor


  • Food waste is found at the bottom of the dishwasher.
  • Food particles may be found near the door seal.
  • When dishes are left in the unit for an extended period before running a cycle.
  • The bottom of the dishwasher is wet from residual water.
  • A blockage has been detected in the drain hose.


  1. Remove the filters and rinse them clean.
  2. Refer to Care and Maintenance Professionals
  3. If you don’t plan on washing the dishes right away, run a Rinse and Hold cycle.
  4. Check to see whether the device has completely drained after the previous cycle.
  5. By calling a professional, clear any obstructions from the drain line.

7. Dishwasher Not Filling With Water


  • Water supply system restriction
  • The previous wash cycle was not completed
  • The delay start is active
  • Household water supply turned off


  1. Check to see whether the water supply valve (typically located beneath the kitchen sink) is open and that the water supply line is free of kinks or obstructions.
  2. Refer to the section titled “Operating a Dishwasher.”
  3. Cancel the delay start or wait until the time has run out.
  4. Turn on the water.

8. Water leaks


  • Suds
  • The track might be separated from the door seal.
  • The exhaust vent is clogged.
  • Improper installation


  1. Dishwashing detergent is unsuitable; use only dishwasher detergents. If suds continue, add one tablespoon of vegetable oil to the bottom of the dishwasher and run a cycle.
  2. Make sure the door seal is appropriately on the track.
  3. Make sure there is no condensation by the evaporative cooler.
  4. Ensure you have sound installation verified by qualified experts (water supply, drain system, leveling, plumbing).

9. Tub stains


  • Water hardness is to blame for stains on the interior of your dishwasher.
  • Tub and silverware came into contact.


  1. The buildup of hard water stains may be reduced by using concentrated lemon juice. Run the Normal cycle until it finishes, then shut off the machine and place an 8oz. Cup of concentrated lemon solution on the top rack, followed by a complete cycle. This can be done regularly to avoid buildup.
  2. When running a cycle, keep silverware away from the tub.

10. Streaks On Glassware Or Residue On The Dishes


  • Setting the wrong rinse aid


Adjust the rinse agent dispenser to match the water hardness. See the section labeled “Adding Detergent and Rinse Aid” in the user’s guide for instructions.

11. Fascia Panel Discolored Or Marked


  • Abrasive cleaner used


Use a soft, damp cloth with mild detergent to clean.

12. Noise During Wash Cycle


  • Dishes may not be correctly positioned on the dishwasher.


The water circulation sound is typical, but if you notice items banging into each other or the spray arms, consult the manual’s “Loading the Dishwasher” section for correct placement.

13. Detergent Dispenser Cover Will Not Shut


  • Improper operation of the detergent cover
  • The previous cycle has not been completed, stopped, or interrupted.


  1. For instructions on opening and closing the dispenser, see “Adding Detergent and Rinse Aid” in the user’s manual.
  2. Refer to the “Operating the Dishwasher” section of the user guide.

14. Unable To Select Desired Cycle


  • The previous cycle has not finished


Refer to the “Running the Dishwasher” section of the operator’s guide.

  4. Hello, My Bosch silence plus 50 dba won’t start. It just make thumping sound every few seconds. I checked the water supply which is good and for any blockages which there were none. Is this a pump issue? Wife’s losing it may have to splash for new one :-))

  5. My Bosch Silence plus 44dba will not run. It makes thumping noise, light indicates it is on, but then beeps after 5 minutes as though cycle is finished. No water issues. No power issues. Help!

  6. Hi, my dishes and glassware taste like soap after using the Bosch Silence Plus 44 DBA. I recently cleaned the filter after noticing suds at the bottom of the dishwasher after I run it. Suds are gone but soapy taste is still there.

  7. Hi, My Bosch SilencePlus 44 dBA has dirty water that has pooled in the bottom after the cycle. I cleaned the filter and a small white plastic piece came out. I don’t know what it is, what it does, or how to put it back in. The dishwasher still has greasy standing water in it. Can you help me get it drained and put the piece back in?

  8. What is the white plastic small basket with the spinning turbine for? It popped out and we don’t know where to put it back.

  9. Illuminator is showing E:15. Dishwasher is making a noise and I’ve tried to turn it on or off and this is not working.

  10. Whoever designed this piece of dung ought to be drawn, quartered, hung and set on fire. Better yet, this individual ought to be sentenced to a life time of using this piece of dung. Unbelievable.

  11. Hi,
    My Bosch Silence plus 44dba detergent dispenser does not open to release detergent during wash cycle. Machine is 5 years old has always worked great up until now. Any suggestions?

  12. The dishwasher run times are off. Completely turned off and run cycles have been done. The 40 minute cycle is now 30. Etc I also have done the “reset” hold action on the large start button on the right side. No change.

  13. Our Bosch SilencePlus 44 dBA has been running great. Yet now it won’t start. Power is on, I’ve done the reset a number of times (it resets to 0:01 successfully), it lets me choose different cycles after turning on/off, I’ve unplugged it for 20 minutes, Checked that nothing is preventing the door from closing completely. Yet it still does not start, the light flashes red but never starts, no sounds at all.
    Any other thoughts??

  14. Our Bosch SilencePlus 44 DBA dishwasher does not clean cutlery – stainless steel forks, spoons and knives – placed in the upper most cutlery rack. The glasses in the rack immediately below the cutlery rack come out clean, but not the cutlery. The sprayer below the glasses rack is free moving.

  15. On/off switch, I pulled the wires out of the plastic plug piece that connects the panel to the door. Is there anyway to order just the wiring?

  16. When my sink was replaced my 44 dBA was unplugged and the water was turned off. After sink installed, water was turned off and dishwasher was plugged in. When I start it it acts like it is going to work and then starts beeping. I’ve turned it off and restarted. I’ve unplugged and left unplugged for over 5 minutes and restarted and still beeps. Help please.


  17. My Bosch SilencePlus 44 dBa stopped running mid cycle and the “rinse aid” light was flashing. I’ve added rinse add, reset the cycle, and turned the breaker off and then back on. The dish washer will come on, but it will not allow me to chose different cycles or will it run if I press start.

  18. I have a Bosch Silent Plus 44DBA. There is an error message “E:06”. Dishwasher will not start at all. Is there anything I can do to fix this problem?

    • First of all, reboot your machine in order to eliminate the one-time glitch from the list of probable explanations for the error. Switch the device off and disconnect it from the socket for 15 minutes. If the code is still shown on the display after you switch the device back on, proceed with inspecting the machine.

      The error can be caused not only by the malfunction of the sensor but also by the dirty surfaces of the tank, where the dishes are located, so clean the tank thoroughly and make sure nothing clogs its inner elements.

      The next thing to do is to examine the AquaSensor and its connections. As some of the wires might be burnt-out or oxidized, others can be simply disconnected. So now you need to find the sensor. It is located on the bottom part of your device, connected to the circulation pump. Remove the left side panel of the machine and you will get easy access to it.

      Check the contacts and clean or replace some if needed. Then test the sensor itself. You will need a multimeter, in case there are no obvious visible damages or impurities on it. Sometimes it is enough to just clean it, but in most cases, the replacement of the element is required.

    • The Most Common Reason Your Dishwasher Soap Dispenser Isn’t Opening. The dispenser may be blocked. Check to see if there’s detergent in the dispenser or on the bottom of the tub after the cycle. Tall items like cookie sheets and cutting boards placed in the lower rack can block the dispenser door.

  19. Bosch dishwasher. Silence plus 44 dba. Door spring apparently broken. Having trouble finding part number for spring replacement.

  20. My Bosch superSilence 44 dB Serie 6 has a pool of water in the bottom well where the filter sits every time after the load has finished, and I can’t switch to half load, I’ve tried turning it off and tried again and it still won’t let me do it

  21. My SilencePlus 44dba wont start up. The red light is on solid. Ive tried resetting, 0:01 is on the display. I then select a cycle, close the door but it doesnt start up.

  22. My SilencePlus 44dba wont start up. The red light is on solid. Ive tried resetting, 0:01 is on the display. I then select a cycle, close the door but it doesnt start up. It said the rinse aid was out, filled it up and the next day it said it was out again.

  23. My Bosch Silence Plus 44dba is not cleaning like it used to. My plates are coated with something gritty and my silverware isn’t getting clean. Glasses have white rings around the lip of the glasses. I have a water softener.

  24. Bosch SilencePlus 44dba is leaving food and a film on my dishes. The silverware and the glasses are also not getting fully cleaned. What can I do to make the dishwasher work like it has for years?

  25. Our Silence plus 44dba is throwing a E09 code. There is no steam or heat that comes out at the end of the cycle and the dishes are not very clean. It happens every time.

  26. My Bosch silenceplus 44 dBA will not power on one day after running fine. No lights at all. Suggestions as to what the problem could be and how to fix it?
