Maytag Dishwasher failed again…

Not that particular issue again – a whole new one! Yay!

I just spent 3 hours following some advice I found on troubleshooting a Maytag dishwasher that lights up but doesn’t run and also the diagnostic guide found on the backside of most kickplates.  As it turns out I think the cable from the touchpad to the controller has corroded internally – the traces are brown on a few wires inside the ribbon:

Corroded Traces in Ribbon Cable

The pin sockets were fine and no obvious breaks in the ribbon itself – so how did those traces corrode?

It’s the kind of component failure that can only occur during manufacturing assembly – the ribbon cable had no holes/tears that would have allowed the corrosion to occur. Unhooking the touchpad lets the dishwasher go into a 2 minute water drain that tells me (via the documentation) that the controller is fine.

Off to find another part…

…. or not. Annoyed that the part that needed replacement, the Control Panel, was back-ordered and $100 dollars to boot, I started working backwards to see just how much of a jury-rigged solution I needed to make to duplicate the buttons.  With the power hooked-up and wiring harness dangling out of the hole where the top of the dishwasher door used to be, I plugged in the control panel and double checked some button presses. Apparently all the activity either unstuck a button or the unplugging and plugging back in reseated a connection somewhere. I stuffed the wires back in, started it up, and dishwasher is finishing up it’s cycle as I type.

It’s like these things are designed to fail, then instead of a $5 ribbon cable manufacturers force you to buy a part that costs about 1/5 the price of a new one.

I’ve got plenty of words for Maytag / Whirlpool right now, but I fear the English langauge just isn’t up to the task of expressing that much impotent rage.
