Whirlpool Duet Washer - Selector Knob Problem - Model Ghw9150pw4

[CheeseheadNV]

The selector knob on our Whirlpool Duet washer either got misaligned or is not communicating correctly with the computer board. The knob is in good working order and I've checked that it is on the stem properly. But the cycle the knob points to is not the cycle the washer is selecting on the control panel. It's almost like it "lost" certain cycle options. When the knob points at "white wash" the control panel shows two dashed lines and no wash temp, speed, etc are selected. When pointed at the Normal Cycle, it doesn't register anything on the panel. When pointed at Delicate and Hand Washables, cycle options register on the panel but I'm not sure they are the correct cycle settings. No matter where the knob is pointed, a hot wash cannot be selected (unless I change the setting using the buttons for wash temp). Wash times and temps register when the knob points to Soak, Soak/Drain and etc. And when I turn the knob to the blank space between the drain options and the white wash, cycle times show on the control panel. We tried unplugging for 1 minutes and a reset didn't help. Any idea what could be wrong and if it is serviceable? Thanks for any tips.

Since you have already done a reset it leaves the user interface as the most likely problem. Looked at a few web sites and part is no longer available. The next sources would be ebay or finding a rebuilder like corecentric.
