Hi Ron

That error message is associated with the situation where the tachomoter on the motor is not relaying the motor speed to the motor control unit which relays the info to the central control unit.

Given that your problem is not permanent, it may be loose or shorted wiring between the motor tach, motor control board and CCU. Check out all of that wiring.

If that does not fix it, you are looking at replacing the motor and/or the motor control board, both very expensive, so try to make sure the wiring is ok.

Let us know what you find out, and just for curiosity, what the heck did the service tech do? I mean, this is info is not classified, didn't he or she tell you this? Did they charge you?

Good luck.

Hi Ron

Thanks for the info, I feel better now that we know you got some guidance from the tech visit.

I would take the drain plug off of the pump and clean out the pump and drain area very thoroughly. It may be that some water is remaining in the system, slowing down the spin and causing the mcu to report the error as a bad tach reading. I really do not understand why running the machine without detergent would avoid the problem. When you tried this did you have a full load of clothes or run it empty? Does it work ok if you put the detergent in with the wash rather than using the detergent drawer? If you ran it empty of clothes then that points to a motor problem, the motor being unable to handle the load of wet clothes in the spin cycle.

I doubt if using the non HE detergent for as short a time as you did would cause the problem, although using too much non HE detergent in these machines does cause major problems.


Anyway, see if you can really scrub this thing clean in the drain system so that all of the water leaves. If this does not fix the problem I think the likely culprit is the motor failing, and being unable to turn the machine fast enough resulting in your error code. The fact that it takes 12 to 24 hours and then works again suggest that the motor is overheating and has to cool down and "reset" before the machine will work again. In short, if you cannot fix this with the drain cleaning a new motor is the likely (but not certain) solution.

Good luck and keep us posted as it will be really instructive what you find out here.

Hi Again Ron

Actually, you are not a bother, in fact to be honest about it we sorta live for situations like this, an interesting problem that does not have a ready solution.

When I talked about the motor failing I don't mean in the traditional sense where it overheats, but in a situation where for some reason the wiring connections are failing (probably from heat generated by the motor). This is one of the few things I can think of that would cause your symptoms, mainly the tachometer wiring heating up, giving a false speed signal which shuts down your machine.

Unfortunately the only way to ever diagnose this is to actually replace the motor, which is expensive and so that is why we are trying to get you to try the other stuff before you have to go that route. My thinking on the drain is that if water is left in the machine it may slow it down enough to cause the problem. Is this grasping at straws, probably.

Anyway, keep at it and keep letting us know what's you find out. As you will notice from the number of views, there are a fair number of folks looking at this.
