Bosch SHU43C02UC/40 Dishwasher Shuts On/Off Intermittenly

Hi,

The issue with your Bosch dishwasher likely lye`s 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 ). This is the purpose of the "1" indicated in the display, a heating problem.

I`d first suggest calling in an authorized bosch servicer, however If you feel capable there`s a way to visually inspect the control. 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. This will be one of the pins from the heater relay, hence the unit sit`s at "1" ( because it can`t heat to advance or until canceled ) trying to heat the water.

**Further to this, if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...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 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, to service your machine.**

Hope this answer`s your question, let me know if I can assist you further. Thank`s for visiting "fixya" for your repair inquiries. Please take a moment and rate this solution and leave a testimony.

Good luck.

How to loose up the circulation pump

Although I previously posted with the same problem of a film on the dishes after cleaning, I did find a section in the owner's manual which solved my problem. Lift up the rinse aid cap on the inside door - the factory setting is on "4". The rinse aid works in conjunction with your local water, which has variations in it's hardness or softness. When your dishes are streaky, lower the rinse aid setting to 1 or 2. If your dishes are spotted, raise the rinse aid setting higher.
