Hello,

Welcome to FixYa.

Based on your description
I'd say the issue actually with the control...unfortunately.


**B/S/H/ also issued a recall on certain models between 1999 - 2006 depending on the model & serial number, you can check with yours, though many not included here still suffers from the same problem...you'll need the serial number too. Here`s the link if you want to see for yourself **

http://microsites.boschappliances.com/safetyrecall/dishwasher/


As I've alluded to the issue is likely within the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this, but not very probable ).

If you feel capable of checking this on your own, there`s a way to visually inspect the control yourself...it really isn't very complicated.

It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board.

The culprit will 99% of the times be one of the pins from the heater relay,

**Flip this over and inspect the solder joints, it will be obvious when you see it.**

This ones new, but it's wheMy bosch dishwasher will not stop running, plus - 9119d99.jpg..

...hence the unit sit`s and takes longer & longer to finish because it can`t heat to advance or unless the 2 buttons for "cancel" are pressed...or takes a long time as I mentioned and eventually display's "1" on units with a display and usually very poor cleaning and obviously no "extra" heat ( aside from the water inlet temp. ) as a result.

You can also run the unit through a regular or econo cycle ...any cycle with the exception of rinse & hold, and with the door panel removed place an ammeter on the gray/black wire it should draw 11 amps during the wash cycle...after it fills and the flow My bosch dishwasher will not stop running, plus - f57273b.jpgcates it has adequate water to engage the heater.

i.e.

**My Opinion - if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...but it has to be done well...or it will not last, although Bosch recommend`s replacing the control and I don`t pretend to speak on there behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)**

**Please disconnect the power or turn off the breaker before attempting any service to the dishwasher.**


If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau/Siemens, to service your machine.

Hope this answer`s your question, let me know if I can assist you further.

    Macmarkus -

    Thanks for the fix info. I found the solder spot, right where you said, and it is indeed burnt out. I'm handy enough to re-solder it, but if it burnt out doesn't that imply a greater problem? If I solder this, could I either a) be back in the guts of the dishwasher to do it again, or b) have something catch fire?

    Thanks for the help!

    Hi Ron,



    The re-solder issue has been a very common one for the Bosch built machines for many years, and according to them it is fine to re-solder the board as long as it is done professionally/proficiently.



    Their first suggestion is to replace the control, however on the new control nothing is done differently and in my opinion and the opinion of many, the relay which handles the current draw for the heater is not rated hi enough ( thus the solder joint fails...addressing your first concern " if it burnt out doesn't that imply a greater problem? " ) and should be replaced with a larger relay, but alas it is not.



    Having said all that, to address your concerns, "If I solder this, could I either a) be back in the guts of the dishwasher to do it again, or b) have something catch fire? " this is why it is important to be experienced at soldering.



    As long as the circuit board itself isn't damaged too bad and you can apply a good clean re-solder it should be fine, in my experience.



    Ultimately it's your call and the judgment to replace or repair. I've personally never had a problem with repairing them so I side on the school of repair, but I understand one choosing to replace as well.



    Hope this helps answer your question. Good luck.



    Regards,



    Macmarkus :)

    We had this problem on our Bosch she45m05uc dishwasher. We opened the front panel, found the unit, and found the bad connection just as described above.

    We bought a solder gun and solder, browsed a bunch of how to solder sites, practiced on junk electronics lying around, and applied a little touch of solder to the bad spot..

    Dishwasher is working fine. It may burn out again -- who knows -- but in the meantime, we feel that the advice from this site was very useful!

    Following the advice here I managed to take out the circuit board and spotted the burned out pin on the back of the board. A friend of mine spot soldered for me and I happy to report the machine is back up and running like it should.

Macmarkus is correct in his description of the failure of the board.

The OP has responded with the correct concerns concerning the risk of fire.

Owing one of these DW's myself, and being the Engineering type that I am, I have determined the reason for the cause of failure is due to the relay being undersized for the application. So much so that I currently stock a heavier duty series of relays, either for Sale directly to those who want to make the repairs, or I will repair the boards sent to me.

Clean Your Dishwasher with Tang (yep - the citrus drink)
  1. Empty the dishwasher.
  2. Run the water in the kitchen faucet until it is hot. (He suggests you do that before running your dishwasher every time.)
  3. Turn the tap off and start the empty dishwasher.
  4. After two or three minutes, stop the dishwasher and add a container of Tang.
  5. Let it run the whole cycle.

How to run self test on bosche dishwasher


Here is an excerpt from "Bosch Dishwasher Troublesoooting".

Running a Test Cycle
Bosch dishwashers have a test cycle which can be run as a troubleshooting measure. The method to run this test cycle is similar across the Bosch dishwasher range so if your dishwasher features seems different from those described below then try experimenting, as the process is fairly straight forward and will be very similar. Bosch dishwasher model numbers are usually found around the top or lip of the door. One of the most common differences between dishwasher models is simply the names of the buttons. For example in the first example below, POWER SCRUB PLUS and REGULAR WASH may be called WASH and ECO depending on your dishwasher model and the country you are in. The other key difference is whether your dishwasher has a display panel (which can display error codes) or not (in which case a program light will illuminate to tell you the fault.
To run the test cycle hold down the POWER SCRUB PLUS and REGULAR WASH buttons. Whilst held down press the ON/OFF button. The lights above them should flash. Now you can check the status of each dishwasher program by pressing its button. Now you can run the full test cycle = Press the POWER SCRUB PLUS and REGULAR WASH buttons again. The dishwasher will start up and when the cycle has ended one, if you have no display panel on your dishwasher model the indicator lights will illuminate if a malfunction was detected as follows -
CLEAN - A temperature sensor fault. If this is the case then the test cycle will be very short as the dishwasher will terminate the test once it's been detected.
RINSE/DRY - A water sensor/filling fault. If this is the problem then the test cycle will not complete as the dishwasher cannot detect the right level of water, the dishwasher will just keep filling and draining again.
WASH - A heating fault. Check your heating element.
If you do have a display panel on your Bosch dishwasher then after the cycle is complete an error code will be shown if a fault has been detected. The error codes are as follows -
0 - No errors have been detected.
1 - A water sensor/filling fault.
2 - A heating fault.
4 - A water filling fault. This can also appear as F on the display during a normal cycle.
8 - A temperature sensor fault.
When troubleshooting your Bosch dishwasher, running the above test cycle is a good start in diagnosing the problem and should give you an idea of where the problem lies with your Bosch dishwasher and what fixes and repair are in order. Our general troubleshooting page will give you some ideas on other things to check on your dishwasher. Good luck!

My Bosch dishwasher was not installed with an "


From an internet posting ::

The purpose of the air gap is too prevent back-flow and siphoning, and newer dishwashers (past 20 + years) have back flow preventers built in and looping the drain hose (not a circle, but an upside down u to the top of the cabinet or behind/side of dishwasher) prevents siphoning. Aside form being ugly space wasters the cheap air gaps have a tendency to spit and cough water out.
