    Bosch Dishwasher Fault Code H
    Symptom: Dishwasher not heating.
    Cause: Possible problem with heating element or thermostat, or wiring issue.

  26. Had Error E9 on Bosch and technicians fixed by replacing thermostat and heating element.
    Now it shows E11 error after wash cycle.
    And dishes seem to be wet at the end of cycle.
    Better then with error code E9 but still not like when new.
    Pretty new machine but Bosch refusing to cover any repairs as I live more than 100 miles away from a certified Bosch technician.

  27. DIY Project Help Tips

    Bosch Dishwasher with E19 error code means there is an issue with the control board. If it is a new dishwasher, call the company you purchased from and let them know.
    If you will have to repair yourself, a control board can be found online for around 100 US dollars.

  28. They just installed my bosch dishwasher and it display and E19 error. How am you fix that?

  29. I had the same E09 showing on a Bosch Silence Plus. I looked up the code on the internet and saw that it could be the heating element, as DIY Project Help Tips suggests below, but after letting it drain the machine works again without issue until it needs to drain again, then it shows E09 and has water in the bottom. It seems this E09 IS actually a drainage issue.

  30. E31 means problem with Zeolite unit – some water could get into it.
    Exchange the zeolite heater and zeolite container.
    – Too much foam in the appliance
    – Appliance overfilled
    Inlet valve / Aquastop letting by appliance tilted backwards.

  31. Dispenser defective > Check component
    Heat exchanger valve defective > Check component – VIB is requested if you have the Heat Exchanger in the machine but the valve may be leaking constantly
    Wires interrupted/broken > Check wires

  32. I have a problem with E31 error
    It will not dry, the water also does not heat up, wonder what is the problem on the Bosch dishwasher model no SMS69EU38/50 bought in Jan 2013.
    Bosch Australia did not honour the international warranty of five years.

  33. DIY Project Help Tips

    Dennis Gillrie,
    Bosch Dishwasher Fault Code E20 = Electrical short or break.
    There is a short causing incorrect resistance in winding of the circulation pump or the motor.
    If you had the pump replaced, it may be a wiring issue elsewhere or to the motor.

  34. I have Bosch dishwasher model SHE53TF6US/01.
    Fault error code is 9.
    What causes the 9 error code?

  35. Dennis Gillrie

    I have a Bosch dishwasher Model SHE3ARF6UC/14.
    I bought it used, installed it and it worked fine for about a month then threw error code E20 and would not plug the water sitting in the dishwasher.
    If I let it sit awhile I was able to get to the rinse and hold cycle and it would drain.
    I took it to an appliance repair shop and they replaced the complete pump and motor, I brought it home, hooked it up and it worked for 2 batches of dishes before giving the E20 code again.
    When I installed it I used new drain hose and have checked that it is not plugged.
    I plan to take it back to the repair shop but thought that I would see if you can recommend anything I can do myself to get this thing to work.

  36. DIY Project Help Tips

    Bosch Dishwasher Fault Code E09 = Water heating problem.
    Most likely heating element issue.

  37. I have a BOSCH DISHWASHER SHE53TF5UC/02 that is throwing the E09 error code.
    Is that the same as a E9 code?
    If different what can I do to resolve this issue?

  38. I have a Bosch SHE58C05UC/50 and I wanted to try and run the diagnostic.
    Do you happen to have the diagnostic procedure for my model?
    My unit runs, fills the bottom and drains but doesn’t spray the dishes.
    Goes through an entire wash cycle and not a drop of water goes through the spray arms.
    I replaced the water inlet assembly but that didn’t solve it.

    My dishwasher is Siemens SN25N881EU. It is error E19, my husband replace 0660 and 0404 part then water button flashes. Can you show me How fix this problem?

  42. Also in my bosh dishwater (mod. smv69u30eu) i’m getting the e31 error. Same problem. At the end plates are still wet and the machines doesn’t heat water. The heat pump were replaced by service person, but the problems still remains. Is there any other way to help overcome E31 error?

  43. DIY Project Help Tips

    Bosch Dishwasher E15 error means water has overflowed into the base pan below the dishwasher. The Bosch dishwasher is now in flood mode. This can be caused by the drain pump having blockage, also it can be from too much detergent and therefore extra SUDS.

    Remove dishwasher
    Tip it forward at 45 degree angle
    Drain the water out of the base pan
    Once drained, reinstall the dishwasher
    Pour a pitcher full of water into the dishwasher

    If the Bosch drains it out but doesn’t wash or refill with water, you have water left in the base pan.
    Basically it senses that there is water in the base pan and keeps showing the E15 error.
    Clean the water out with a shop-vac or similar and get it 100% dry.
    Once completely dry, the Bosch dishwasher should not show the E15 error again.
    If it still shows E15, this means a sensor may be bad (overflow sensor) or there is still water in the base pan.

  44. I have a Bosch Dishwasher Model Number SMS50T06GB, I have an error code e15 on it. As per the comments I have tilted 45 degrees, left switched of for a week and still the same when you turn on, error code e15.
    Any further help with this would be much appreciated.

  46. Hi,
    I’m getting and E17 error message on my bosh dishwasher. There is nothing obviously wrong with it. I cleaned the filters even though they were not that dirty. There was only about a cup of water in the filter section. There are no blockages in the rotating arms.

    The dishwasher runs for about 2 minutes at the start of a program, then goes directly to the last minute of the program (showing 0:01 on the timer). It drains itself, then puts up the error message E17.

    What can I do?

  47. DIY Project Help Tips

    Is the Siemens dishwasher is showing error E25, this means the pump impeller may be blocked or jammed up or the drain hose is blocked.
    Can you hear the motor/pump running?
    Was the dishwasher draining properly?

    Check both, clean out if needed, and reassemble.
    If the error code comes back after cleaning out the pump and drain hose, try unplugging the dishwasher for 24 hours or so to reset the board.

  48. My Siemens dishwasher SR657080GB/17 was displaying E25 but that has stopped and it is only displaying 1 minute.

  49. I have the same issue with error code E19. I could say that reset power for a couple of days did not help at all. This code shows in 2-3 seconds after dishwasher turned on, and then it do not react to any buttons. With my unit it appears during night wash. Machine stops with dirty water and highlighting “Need salt”. Salt addition did not help also. It s a Bosch Dishwasher SPS53M22EU.

  50. I have an E19 error on Bosch dishwasher.
    Second time with this error.
    We often do short washes and I think this may cause issues as maybe machine does not get hot enough..
    Last time we mopped up the water in the bottom of machine and checked filter (no debris as we rinse plates prior to washing).
    Left machine overnight and it worked following morning.
    This time same issue with water, we have done the same thing but so far error has not cleared.
    I don’t want to call a technician for a bit of grease on a sensor or something like that.
    Machine is only 4 months old.

    Samantha Rowe,
    Bosch Dishwasher error code E01 means the water will not enter the dishwasher as fast as it should.
    Be sure you get good water pressure to the dishwasher.
    If you have good water pressure, the dishwasher water fill valve may be clogged or faulty.

    Bosch Dishwasher error code E1 means that the water is not heating as required.

    Bosch E31 is heat pump issue.
    If many parts were replaced and the error E31 keeps coming back, then the heat pump is most likely the issue.
    The pump may be leaking and causing the water to drip down into the bottom.

  55. DIY Project Help Tips

    Bosch Dishwasher Error E31 does indicate a Heat Pump Issue.
    You may just have a faulty connection on the heat pump.
    Check to see if the connection is secure.
    If so, the pump may be faulty and needs to be replaced.
    You can test it with a meter if willing.
    Check it, then let your landlord know if you suspect the pump needs replacing, then a tech can be called if needed.

  56. I am getting the same.
    My dishwasher model number is SMU53M72SK/93. The wash seems to finish, but the dishes are left wet, and the cycle ends with error E31.
    I read on an Italian support and repair site that I have to “check and possibly replace the heat pump”. I am not directly responsible for the machine, as it belongs to my landlord, I only allowed to perform standard maintenance and clean up, so I need to figure out whether or not I need a technician.

  57. I am getting an error code E31 on my Bosch Dishwasher model SMV 69 T10 with zeolite dryer. Machine doesn’t heat water and all plates are still wet. Service person disassemled dishwasher, checked and said that heater, pump and main controller are OK, but (maybe? -he wasn’t sure) there is a water leakage somewhere inside and electronics blocks both water heating and air dryer. He suggested replace assembly for 400 euro. I’m really surprised with such approach and price. Is there any other way to help overcome E31 error?

  58. I have a Bosch dishwasher model SGI55M05AU, the dishwasher operates but no longer heats up the water and the wash cycles are shorter. No error messages come up during a cycle but I get an E6 error during the self test. Is this a faulty aqua sensor or does it need a whole heater assembly.

    Lisa Auciello,
    Clean out the strainer at the bottom of the dishwasher. Check for any chunks of wax that might have gotten anywhere else and remove by hand. Then run the dishwasher with HOT water and ammonia… as ammonia that will cut through the wax. Do this multiple times without any dishes in the dishwasher and eventually the wax in the dishwasher will be gone. You may have to run the dishwasher 10 to 15 times with only HOT water and ammonia to fully remove the wax.
    NOTE: Do not add dishwashing detergent to the dishwasher when cleaning with HOT water and ammonia to remove wax.

  61. I accidently put a wax item in my dishwasher. It has coated everything! The washer will not run. I have tried to pour boiling water down the drain. I have tried ammonia also. I have tried to run the washer and the water just gurgled in the well, once started it wouldn’t let me turn it off. I have not seen any codes…

    Sarah Tacon,
    The Bosch dishwasher E24 error code means a drain error, this also can mean an issue with the circulation pump or main control board.
    Check the drain system and be sure the filter is not clogged.
    Also be sure the check valve is in place and operational.
    If all checks okay, replace the board.

    The Bosch E15 error means water is in the base pan…
    If you cannot move the dishwasher… let the dishwasher just sit unused for a week or so and the water in the base pan will evaporate. You could put a fan near it to help evaporate the water.

    To fix it properly…
    The Bosch dishwasher will need to be tilted at a 45 degree angle forward to clear it.
    E15 means that water has gotten into the base pan below the dishwasher and it is now in flood mode…

    Bosch Dishwasher Error Code H04 = H04 is not considered an error code on Bosch Dishwashers.
    Someone may have pressed and held down two buttons when turning the dishwasher on. Unplug the dishwasher for 5 minutes and see if the display resets itself. If the H04 does not clear, you may need a new control board.
