Power Surge - Now Dead

Power Surge - Now Dead

This morning we had a storm and lost power. There were several surges as the power came back on. After I got power back and was resetting clocks in the kitchen I could smell an electrical burning smell vaguely. It seemed like all the appliances were working, but I did not check the dishwasher. The wife did this afternoon and it is completely dead, no response. I have turn the breaker off for 10 minutes and back on still nothing. My thought is the control board's probably fried. Any thoughts from anybody else? Thanks in advance! Whirlpool Gold Series Model # WDT780SAEM1

"Hi @seattlekev ,

A burning electrical smell is not a good sign.

It may be that the electronic control board has been affected by the power surge. The only way to tell is to open up the control panel and inspect the control board for damage.

Here’s a link that may be of some help as it gives the layout of the parts in the Control Panel and also the cost of the control board (part #8).

There are other suppliers if this one doesn’t suit. It was shown just to give you an idea of the cost and location of the part

If you get storms/outages frequently, for the future have you considered having the dishwasher (and other appliances as well) connected to the power outlet via a surge protector (some are inbuilt into powerboards (powerstrips?) etc. At least if a storm or outage occurs it will be sacrificed and not the appliance. The downside is that most surge protectors do not indicate when they have failed (or operated if you like) so after a storm you’re not certain if the protection is still there or not as the power is still available. The better ones do but their cost makes having a few around the place debatable.

As an aside, check the provisions of your Home Contents Insurance policy to see if the home appliances are covered for damage by storms and outages.You may be able to get it repaired/replaced under insurance. Just a thought."

"Hi @jfab

If there is no power at all on the dishwasher then looking at the dishwasher’s tech sheet, there is a thermal fuse, part #4 Control panel and latch parts diagram in the main power supply path to the control board, that may be worth checking.

Here’s an image from the tech sheet wiring diagram showing the fuse (shown as “non resettable bi- metal”) connected to the active input lead.

(click on image to enlarge for better viewing).

If the fuse is OK check the control board for any obvious component damage"
