Any washer gurus in here? I have a WF328AAW/XAA (Vibration Reducing Technology) that threw E3 codes and would quit but I could restart it and finish a cycle. It vibrated horribly and I took to holding onto the drum with the top off to do a load while a new main board was on the way.
I installed the new board today and it's worse. It throws out E3 and won't restart. I have to turn it off and attempt to redo the cycle but each time it only runs for maybe a minute.
I pulled the stator and rotor off and the bearing looks and feels perfect. The drum spins very freely. The windings all text out at 11.8 ohms. I can't find anywhere how to test the Hall Effect sensor. Anyone know how?
I reinstalled everything with dielectric grease (long shot) with the same results. It runs for a few seconds and the motor acts like it's binding up, stopping and trying to turn. I power it off and the drum is a free as can be.
So I think either I have another bad main board, or they are both good or the Hall sensor is bad. How can I test it? And it looks like a one piece design, no screws but it looks like it would pop off of there. If it's bad can I retrofit one or is it replaceable?
I've been to that site weeks ago and provided the numbers o the machine. That's how i got the part. Do you have any knowledge you can share?
edit to add:
After more research I found out how to test the Hall sensor. The two power leads need to produce 3.75v on this machine. Mine seems to be OK, it produced the volts but the motor stops and acts like it's bound up, the voltage doesn't change on the sensor when it does this. Then it errors out with E3.
