A single touch key has been continuously sensed

From Service Manual 257796, p.48:

1.Press the ON/OFF key one time to release the E1 display, then operate the desired key normally.

2.Measure control board supply voltage at the test points. Expected: 12 VDC and 5 VDC; a drop below 4.75 VDC on the logic rail points to a failed onboard regulator.

3.Inspect all connectors on the main control for corrosion, thermal stress, or backed-out pins. Reseat each connector with the power disconnected.
