Thermador Dishwasher Cycle Status: Red dot

SOURCE: My thermador dw44zs dishwasher:

There are a few possibities...
if you remove the lid and take the two t20 screw off the left side panel at the front you could check the pressure chamber and its hose are not blocked. Use the link and go to page 4, part 0426 and 0424. You can also remove 0418 (remove t20 screw via the sump after all filters are removeds) this will expose the pump impellor and you can check for any obstruction. If the d/w is connected via a sealed spigot to the sink, remove the grey hose and unscrew the spigot adaptor from the sink and ensure there are no blockages. There may be water in the base of the d/w (base as below the tank, not under the filter) this will activate the flood safety, so check valve, hoses etc for leaks. You will have to manually clear the water from the base pan to deactivate the safety device. Sit the front of the d/w on a large towel and tip the whole unit forward, the base water will then come out. Whilst you have the side panel off, check that the red rod connected to the pressure chamber is not activating the microswitch.

Hi, Welcome to FixYa. Since this model Thermador is a B/S/H/ built ( bosch...provided the model is indeed DW246US ) machine let me know what you want to service and I can provide pretty much any service guides, info and direction on what or how to proceed. Macmarkus :)

Hello,

Welcome to FixYa.

Based on your description I'd say the issue actually with the control...unfortunately. This is commonly associated with a heating fault.

Since 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 ). These are the steps you'll need to follow to resolve it or at least investigate.

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 where to look...




...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, no heating 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 switch indicates 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 their 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.
