I have the F35. I opened the washer and got the IC/pressure sensing board. I read that the pressure transducer is supposed to read from 1 to 5V. The reading on this one was 1.21V. Using a hose I put pressure into the sensor by way of mouth to confirm that indeed the voltage out of the analoge pin 4 goes from 1.21 to 5.#Volts5.25Volts. As I did this, the machine responded by turning the pump on and off depending on how much pressure I put in. So I think that lowering the input voltage from 5.25 or so to the nominal 5V will fix it. this is because the analouge sensor will sense higher than 1 volt while the digital converter will always want 1 volt to mean 0pressure no matter what the voltage is. I think the voltage supply in the main board drifts up higher than 5 volts and thus ruins the signal from the analougue sensor by pushing it always higher than 1v. This means to the machine that the pump must keep running. It would then have a time out on the pump so as to not burn it and falsely detect "SUDS". At that point it would also through the F35 error. I will confirm this soon.
