Rochelle K. for Model Number SHU6805UC/12 I have been told that the control board on my Bosch dishwasher has failed. The diswasher starts at 2h never finishes, fills with lukewarm water and doesn't drain completely, unless I manually hit the drain button. The dishes also so not dry. Do I need a control board or is it a heater? if so what part do I need to fix it?
Answer Hi Rochele. The 2H code is that either the incoming water temperature is below 120° or the heater has a bad circuit. Check the both of these. Run the water at the sink and test the hottest to compare. If you need to raise the water heater temperature, then this may fix it. If you can clamp on a amp probe around the red heater wire to see if it uses 10 amps. of power. If you have no amps, then test for 120 vac to insure the control board relay output is OK and the wires to the heater are OK. If there is voltage then you have a bad element. Part # 00480317. If you do not have voltage then you have a bad control board part # 00266746. Control Module - Made by Bosch. Common program control module for Bosch dishwashers SHU53/68. NOTE The manufacturer has redesigned the cover and indicator lights. Lights may be covered by the plastic case. You may have to remove the square covers over the indicator lights if needed. The same case is used for 6 and 8 indicator light models. They also no longer use the red bulb indicator lights, small surface mounted lights are used instead. Thank You. Read More...
