    Water does not heat up during wash cycle so it never advances, just stays in the wash cycle forever if you let it. It ran all night one time, so I posted a question and Richie suggested the heating element. My email is sassydeel@yahoo.com. Thanks

    Oops found it after testimonial. So sorry. Yes if you could please send me the manual to sassydeel@yahoo.com. Your help is much appreciated as I am hoping this indeed is the problem. Part is approx $8.00 much cheaper than replacing the dishwasher.

Hello sassydeel, changing the heating element is quite a job, but are you certain you need one ? I ask because I have serviced Bosch built dishwashers for alomst 20 years and I have never seen an element faulty, that's not to say I haven't seen heating issues or it doesn't happen...I'm just saying how rare it is, so make sure it is faulty. Have you confirmed it with a meter ? Let me know, and if you'd like to provide an email address I can send you a complete repair manual via "pdf" through email. Macmarkus :)

    Hello again,



    Thanks for the reply, I want to start by saying I don`t want to step on anyones toes, but I don`t want to see anyone spend money on parts that are not likely at fault.



    Having said that I`d first suggest checking the thermostat inside the door panel, based on you description of the timer not advancing and the water not heating. The SHU 30** unit`s with a mechanical timer have very few if any, issues with the actual element as I stated previous. If the thermostat within the door panel is not satisfied, the water won`t heat, hence timer will not advance.



    ** Turn off the breaker at the service panel before attempting any service suggested **



    If you have a #20 torx screwdriver, remove the door panel by taking out the screws around the panel ( watch the edges they are very sharp ) Once the panel is removed you should see the thermostat over by the detergent dispenser clipped to the inner door. Remove it and test it, you`ll need a ohm meter/multi-meter plus a lighter or match to heat it up( or carefully set it on a stove burner for a few seconds until you hear it "click" or watch the meter move if it has alligator clips to fasten to the thermostat connectors..don`t burn yourself or the wire leads ) to see if it open`s & closes.



    I can send you the training manual later, but I`ve got run off to my "day job".

    Let me know how you make out in the mean time.



    Good luck.

    Hi,

    I have to make a slight correction to what I said this morning ( it was early and I was still half asleep !). If the problem is what I suspect, (thermostat inside the door) the timer doesn't advance and the water won't heat because the thermostat IS open which would tell the heater it IS satisfied. It should be in the "normally closed" position and open on the rise at approx. 160f. which then shuts off the heater, if it stays open when it should close (after cooling) than the heating element doesn't come back on. There is the rare case the 185f. hi-limit thermostat goes as well, but not very likely unless the flow switch and circulation pump both failed first. I hope this makes some sense to you. I didn't realize what I'd wrote and how I phrased it until I proof read it now...better late than never I hope.

    Sorry if I caused any confusion in the mean-time. Let me know how you make out OK. Do you want me to send you the training/service pdf file via email ?

    Regards,

    macmarkus :)

Bosch she56c02uc dishwasher does not cycle, stuck on wash


If the display is stuck on 2H it often means the heater is not working. If the water is not heated, the cycle will never complete. It is possible the heating element is bad, but a more likely problem is with the control module PC board. The solution requires some basic repair and soldering skills plus the tools to do the job. Bosch recommends re-soldering the connection to the heating element relay (see page 11 of "SHU/SHI/SHV Dishwasher Troubleshooting Tips") free download here The problem is that the circuit board copper is not heavy enough to handle the heating element current, causing the copper to heat and melt the solder connection. A better solution is to solder a short length of copper wire between the two pins to provide more copper and reduce the chance of heating as shown in the attached photo.

Bosch SHU 3032 dishwasher gets stuck halfway through the wash cycle and just continues to wash until you manually advance it. I turned in on before bed one night and it was still running the next morning....


Hi,
It obviously sounds like a timer issue here, and as it's embedded in a big chip on the control board, I would think a new control board is needed.
The exception to this is if it is not heating at all, in which case it won't advance if the water is not hot enough. Try it again and see if it gets warm.
If not - replace the heating element.
Most machines just stop to heat up the water, but to cut down cycle time they may recirculate the wash-water first to speed things up.

Bosch SHU 8805 upper arm is getting no water.


replace the upper water arm conduit and wash arm hub as they leak under years of pressure and the o-rings leak water and then it can't hold pressure and supply the upper arm with full pressure water,also replace the center arm conduit if it has one as this will wear out too

My Bosch shu 42 just stopped cleaning. there is soap residue also on the dishes. It doesn't seem to be getting really hot water. We cleaned the filter and made sure it was loaded correctly.


When the heating element fails on dishwashers, the wash cycle water can not be heated high enough the activate the DW detergent powder.

Replacing the heating element should fix you right up.

Also, resist the temptation to switch the a cheap, generic powder. A brand name e.g. Electrosol or Cascade powder is proven to work well. The ultra-cheap powder will leave white patches on the dishes and it will not dissolve completely, even when the heating element is working properly.

Good Luck!
