Dishwasher Totally Unresponsive

Dishwasher Repair

Ok - I replaced my control panel about 3-5 days ago, due to the fact that my Start button no longer worked. Turns out it may have been another part at fault after all, because now my problems have compounded.

Dishwasher worked fine since then - except some of the cycle lights wouldn’t light up, even though the buttons were functional.

However, even though it sat idle all day, and worked last night, nothing works. No lights, no functions, no nothing. Flipped breaker a few times. No dice.

Is this an indicator of a failure of some other major component, since the Control Panel is now brand-new? I am all for replacing components myself, but it sure would be nice to know where to start! Or is it time to get out the Yellow Pages and call the repair guy?

Thanks.

Here is the tech sheet

Could be a number of things.
First check to be sure the connection to power is OK re: usually wire nuts.
Also a good idea to check that it is getting voltage. Otherwise you could rip the whole thing apart and perhaps it is a bad circuit breaker.

Next on the list would be the thermal fuse Item 6 in Section 2.

Next would be the door latch switches but I believe the unit/controls are still live with the door open.

Unfortunately the tech sheet does not show the wiring for the LEDs so it makes it difficult. Is it possible that you hooked something up wrong. re: the ribbon cable etc.. I do not know if the cable is keyed so that it only goes in one way.

This is a bit of a puzzle as the thermal fuse should not blow when the unit is just sitting idle. Note these fuses are know to be a problem and that is why there is a modification fix/harness included with it.

Try flipping it and leaving it off for half an hour or so. I am not sure how long it would take this board to reset. I think this would be a long shot but worth a try.

Cannot say but if you decide to try and fix it yourself I recommend you get a meter. This will let you check power and also continuity of the connection etc.

Thanks a lot for all the detailed information - that’s really helpful. Based on the symptoms, I suspect that the thermal fuse may be the culprit, because the breaker seems OK, and I have no reason to suspect that the DW somehow disconnected from the house hard wiring at this point.

Weird thing about the thermal fuse, though - the diagram seems to show that it’s part of the control panel assembly, yet I cannot find it anywhere. Is this fuse assembly buried somewhere down deep in the door? I started to take that off, but it looked like I risked cracking some of that sound-dampening foam stuff down in the door itself if I took it too far.

Thanks.

Should be on the component side of the control board.

Thanks for the feedback - I don’t have a meter, exactly, but I pulled the thermal fuse and bypassed with (blushing) a piece of wire and two strips of masking tape. So – with that fuse out of the loop, all works. Now, at least I know that a $13 fuse assembly will fix it!

Thanks again.

Your Whirlpool dishwasher trouble sounds identical to mine, including only a few LED lights working, etc. I had a pro come out, and he said I needed a new control panel, which contains the touch panel, which he said was the problem. Unfortunately, that part in bisque costs $350-$400, about the replacement retail cost of the dishwasher itself! Even wierder, the same part in black or white was only $150. Go figure. I was disbelieving of that, but checked it out on the internet parts sites, and he was right! Can you tell me where the thermal fuse is located? I disassembled the control panel but couldn’t find any fuses. I would hate to buy a new one if only a fuse needs replacing.

Thanks,

Robert

Your problem is different if the fuse blows nothing works as it kill power to the control board.

I did notice you had another post so will reply to that one.
