Ran calibration and it passed. Tach test wouldn't run -- Set both lites per instructions, pressed enter, no response and only Spin light lit. Tried an Actuator replacement. Also removed belt guard, belt, etc. to visually inspect tranny and splutch. All looks good. Unit will wash fine but just spaz out and do its own thing. Countdown timer gets to 1 and then the pump starts running forever. Pump is pumping fine with no obstructions -- checked that as well. So then I'm left with harness and control board.
