The other night I went to start the dishwasher and there was no response. It worked fine the night before, and there was no unusual electrical activity in the house that day. I checked with a meter and there is power to the on switch. I purchased a new switch and changed it, but that didn't change anything.

Does anyone have a suggestion on what I might try next?

Thanks,

Remove the control module and inspect it for a burned spots. As far as I know you already fixed a broken solder joint once before (http://forum.appliancepartspros...ssembly-replacement.html). It is probably time for a new control module.

Here are the break down diagrams and Replacement parts for BOSCH SHU6805 UC/06 (FD 7705-7912) | AppliancePartsPros.com

Just replaced the control module, unfortunately there is no change. Still no signs of life, although power is still there at the switch. Any other ideas?

Thanks, Tim

Tim,

Did you check the switch on the door latch?

Also check the incoming power to the control module according to the wiring diagrams and instructions in the troubleshooting manual from one of our previous posts: http://forum.appliancepartspros...troubleshoot-manual.html

Gene:

When the door is closed (engaging the power switch) and the power switch is placed in the "on" position, I register power at the incoming connection to the control panel. Still no activity though.

Is there another fuse somewhere else in the assembly? I see nothing in the front door area that is burned out.

Not sure what else to check, but somewhere a connection is not being made, and since the control panel is now brand new, it doesn't seem like it could be that.

Thanks, Tim

Are you able to run the self test?

Unfortunately no, I get no signs of power at all. There is no response, lights or any actitivy when I engage the on switch. I have been able to verify that when the on switch is engaged, there is power coming to the control panel, but none of the lights anywhere on the unit come on, even for a moment.

Thanks, Tim

Tim,

Can you be more specific on how did you do it?

I used a meter, one lead to a ground, the other lead to the end of the grey/black and black wire connection that attaches to the control panel. When the door is closed and the switch is on, there is power. When the switch is off, there is no power.

According to the wiring diagram you have to measure the voltage between the Black wire (I2.1-2) and the White/Red wire (I2.1-1). Possible the white (neutral) wire is broken or there is no continuity between the terminals 1 & 2 on the "on-off".
