Good day all,

First I just want to say that this site is proving to be invaluable for me and I thank the samurai man for putting this together.

I'm new to this and had a question regarding this dishwasher. The unit is off and has no lights or reaction when pressing touch panel (user interface). The thermal fuse and door switch check out ok. Power is getting up to the control board and the neutral is good as well (checked with a light bulb).

Seems like all that's left is defective touch panel or control board. These items are obviously not cheap and up here in Canada we don't have such return services as offered by repair clinic : (

The tech sheet is missing from the dishwasher but I tried a diagnostics mode by pressing "heated dry","normal wash","heated dry","normal wash" and nothing. Can anyone provide an insight on how to rule out touch panel? I would imagine that when these fail, it's one button at a time?

120v AC between

That is correct. I have 120v AC after door switch and past thermal fuse as well so up to the control board.

as referenced to the Tan wire on P8 ?
then it would seem to be a bad Controller

Thank you for the help. The reading was in reference to the tan wire on P8. I will report back if my client decides to fork out the money on a new board.

Cheers

I wouldn't be so quick to believe it's the main control board. Very seldom do I see these controllers going bad but see touchpads going bad all the time.

These membrane touchpads made by all manufactures are notorious for going bad and getting no response or keypads sticking.

Thanks for the added input. Could you share how to tell if the touchpad is at fault if there are no lights or response?

[Budget Appliance Repair]

That is the general signs of a bad touchpad. If the tech sheet has a keypad matrix then look for what two ribbons are for the "CANCEL" key. Disconnect the touchpad ribbon cable and short the two pins that are for cancel on the board.

Generally if you can get the control to do a 2 minute drain and stop when cancel is pushed then the control board is OK.

Thanks for the help. I will do that next time I encounter this problem. Unfortunately the touchpad for this machine is factory order from my suppliers here and 4 week delivery plus $170. My client would rather a new dishwasher instead so no chance to check your ancient samurai techniques this time.

Maybe one day repair clinic will ship to the North.

Most Whirlpool boards will also defualt to drain if you remove power, disconnect the touchpad ribbon, and then reconnect power with the door closed. Lets you know that the control is sensing a missing keypad = control board probably OK.

Thanks Chat_in_RI, that's some very good info to know and remember.

I thought I had read somewhere something like that but something more to do with disconnecting the sump thermistor or something like that and only available in some models, (wasn't at all sure about the method so didn't mention or try to explain it).
