I'd like to revisit this issue... I ordered the door latch assembly and replaced it this morning. No change in the symptoms. More info: I set it on normal wash and press start. It shows me "56" minutes on the display, makes a quiet buzz for about a half second, then blinks "PAU" in the display alternating with "56". If I press start again, it does the same thing -- short buzz then alternates "PAU" and "56".
When I repeated the original process, which was setting it on spin/drain and pressing start, I get the same symptoms as before. It shows "13" and clicks a couple times. If I let it sit it will eventually count down to "12" and click some more. No water, no spinning, no activity at all.
A note on the door latch: When I ordered the latch, they told me I would need a wiring harness and strike plate. I assumed that was because the latch was a compatible replacement but not the original, and that the connectors on the latch would be different than the connectors on my existing wiring harness. When I removed the latch mechanism, however, I found the existing connectors matched my new latch just fine so I did not replace the wiring harness (nor the strike plate, which also matched mine exactly). It seems to me that it wouldn't be likely that a wire would fail and more likely that the latch would fail.
I hesitate to open the wiring harness and try it just to see if it works because it is the most expensive part of the whole job ($130) and I can return it if I don't open it.
Any further suggestions before we go buy a new washer?
1. Faulty latch: I've replaced the latch and have the same symptoms. It seems by all rules of cause and effect and logic, that the latch assembly cannot be the problem, unless I coincidentally got a bad latch assembly from the store. That doesn't seem likely.
2. Wiring harness needs to be installed: I assume the way you know if you need the wiring harness is if the replacement latch does not have the right connectors for the existing harness. My replacement latch matches my existing wiring harness. So I don't absolutely need the new harness. The other possibility is that there is a wire in the harness that is broken or a connection that is bad. I removed and re-seated all the connectors on the display board with no change in symptoms. It seems highly unlikely that non-moving parts like wires would suddenly go bad and need to be replaced, so I hesitate to open the $130 bundle of wires when it's unlikely that's the cause.
3. Display board isn't detecting that the door is locked. The "door locked" light comes on. The machine goes through the paces of firing solenoids as if everything is working. Things click and the timer counts down (at least to a point -- I suspect it eventually figures out the tub isn't filling). I don't see any sign that the display board doesn't know the door is closed. In fact, it seems to behave as if the door is closed, except nothing it tells the rest of the machine to do is actually happening.
So I'm at the point where I'm weighing the option of having someone come in and look at it or replace it. I'm concerned, though, that any service person would just start grasping at straws at my expense and install the wiring harness, then replace the display board, then the water valves, then the drain pump until he discovered the real problem.
I'm not convinced we're on the right track.
I found an online copy of a diagnostic procedure that we should've done right out of the starting gate. You press a couple buttons on the front panel and spin the knob and different things happened. I got E56 every time I asked it to agitate or spin. I did the diagnostic checks on the motor, which said the motor is OK but the speed control board needs to be replaced.
So what you're saying is that the error code might be something from months or years ago that isn't related to our problem, and the fact that the machine displays the error code at the same time it does not spin the drum is a coincidence??
Going to go find the refund button.
The error code appears during the diagnostic procedure when the machine should be commanding the tub to do something. During those diagnostics, the machine turned on the water, activated the drain pump, locked/unlocked the door, etc. as expected but when it tried to spin the tub, I got E56.
