My problem was the two 2200uF, 10V electrolytic filter caps were bulged on the main board. Typical symptom of overstressed capacitors due to high ripple current and insufficiently low ESR. (trying to skimp of parts) Tip off was 0.38V on the analog output of the pressure sensor when power was off, 1.1V+ when the power was turned on, without any water in the drum in both cases. I unfortunately wasted $$ on a new sensor which did nothing.

I desoldered the two caps and put in two 2200uF, 25V Nichicons. All works perfectly now.

I desoldered the two caps and put in two 2200uF, 25V Nichicons I had lying around in my parts collection. All works perfectly now.
Take a picture of all the connectors before unplugging them all. It takes out the guess work when putting them back on.
