Miele W961 motor fail

[askomiele]

Hi everyone,
My miele Gold 2000 (w961 wps) got showered last night! One the central heating pipes developed a leak. Water seeped on the machine and made its way in the controlboard of the machine.

I opened the machine up and let every dry out for 24h. Everything seems to work fine, except the control of the motor is messed up. As you can see in the video I posted downhere, the motor doesn't seem to get the feedback to turn the drum around. (Not the best quality but hope that will do)

I'm willing to spend some time repairing this machine, so the question is... what is failing? The maincontrolboard? The speedometer (tachometer)? The motorrelais?

Let me know your thoughts!

Oh and before you attend me on the blinking light... I putted the machine in test mode, there is nothing wrong with the lightsignals...

What happens when you try a regular program?

Does it surge?

Its hard to diagnose since it could be any part of the system that controls motor speed aka the voltage of the tachometer.

First, I'd check all the connections, both on the motor side and the electronic side.
Next, I'm not quite sure if the tacho on the motor is seperarte or integrated into the motor (our W961 has been gone for more then 3 years now). If it's seperate, I'd first try to replace that.
And then, last, the control board is a posibility. Actually, the back one in this case. (For those who don't know, this was one of the first Miele designs were the power electronics were mounted on the back of the programm control bord.) However, these parts are really REALLY expensive. There are some shops online and on Ebay which will offer repair for these which might be a good option. You'd have to do the job completle yourself then, and I'm not sure if exchanging the power electronics requires a reconfiguration of the PCB.
I know that the part is 180€+ from Miele Germany, and the service bill for replacing it will probably be above 300€.
These repair services demand something like 70€ or maybe even 100€, but that still would be cheaper.

Is it dry?

Under the connector that joins the control board (edpw200) to the relay board/motor controller (el200)?

What about the board at the front of the motor which houses the tachogenerator and the brushes? Dry, dry, dry?

Did you unplug the two boards and dry them thoroughly?

Found an excellent website. One of my favourites on fixing.

Thx for replying

48h of drying out and the machine works beautiful! 17 years of service and counting. I checked everything else, just in case but all in perfect condition.

Congratulations on the resurrection. 240 volts of pure bliss. It's hard to keep an old Miele down. DAMHIK.
