Bosch SHI6805 dishwasher runs, counts down to "1" and never stops. Except in quick wash mode which runs properly to CL. Water appears to never be heated. Test Program = "0". Ohm meter testing: NTC = 54.5 ohms at 78 degrees F. High limit switch = 0 ohms. Flow switch = .4 ohms. Heater red to red terminals = 11 ohms. Wiring through door for heating circuit appears good. Is there a test I can run to confirm my diagnosis of control board faulty? Thanks in advance for your time! - Mitch
There is not a test mode that you can run the unit through in order to determine whether the control board is operating. To find this out you will want to test the control board when the unit is cycling to make sure that it is sending 120 vac when the heater is supposed to be on and if not then the control module would need to be replaced.
