GE Profile dishwasher making a high pitched squealing noise from control board

This little repair tip is for the GE Profile line of dishwashers with model numbers that begin with PDW, such as PDW9280J00SS.

You load your GE Profile dishwasher and go to start it and… it won’t start. Even more confounding, you hear a high-pitched squeal coming from the control panel area. You cut power to the dishwasher (and the squealing stops) so you can disassemble the panel to get some earballs in there. With the panel open, you reapply power and can absotively, posilootely tell that the noise is coming from the control board. To make sure it’s the circuit board and not the touchpanel, you even disconnect the touchpanel from the circuit board so the touchpad doesn’t have any power and couldn’t make a squealing noise even if it wanted to.

So you order up a new control board from RepairClinic because they have great prices, super-fast shipping, and a 365-day no-hassle return policy on all parts, even electronic parts that have already been installed.

The new control board arrives at your door immediately after you click the Send button on the part order at the RepairClinic site. You slap that board in and… it still makes a high pitched squeal!

“Must be a bad board,” you mutter to yourself, while packing up the board to send back to RepairClinic for a replacement. The new board is on your doorstep waiting for you when you return from the Post Office. You slap it in and… it still squeals!

Finally, you go online to the mostest awesomest DIY appliance repair website on the whole Innernet *and* the Outternet– Fixitnow.com Samurai Appliance Repair Man– and you find this very post that you’re reading now. “Dayyam,” you wonder to yourself,”how’d that Samurai know what I was doing with my dishwasher? He must be one o’ them psychotics who can tell the future, an’ all.”

Well, you could say that. Or you could say, “Samurai, what in tarnation is goin’ on wif my dishwasher?”

What’s going is that the circuit board will make a squealing noise when one of the keypads on the touchpanel has an open or shorted keypad. So, when the touchpanel is disconnected, the control still senses an “open” and will squeal– same effect when a keypad on the touchpanel is shorted or stuck.

To fix your dishwasher, replace the touchpanel.
