    Default Cabrio Fault Code F50

    Model Number: WTW6400SW2
    Brand: Whirlpool
    Age: 1-5 years

    Well the wife is fit to be tied. Our Cabrio washer, Model WTW6400SW2, has set a F50 fault code. It is less than two years old. I know that code is usually a problem with the RPS sensor(W10183157). I didn't have time to work on this problem so we called in a service tech. He ordered a replacement sensor and tried to put it in today. We still have the same fault code with the new part installed. The tech called Whirlpool and was told that the sensor and control unit have to be changed together. We are in for over $500 on this repair so far and it still doen't work. Any comments or suggestions would be welcomed.

    I hope at least the tech(?) did some checking before ordering an RPS board. The F50 is usually associated with a motor or motor controller (main board) failure, but I have also seen it caused by a faulty wiring harness, or even something as simple as a sock stuck between the basket and the tub. I am not aware of the RPS needing to be changed together with the new board as they are not 'matched' components. My suggestion would be to make sure the tech is following the test procedures as outlined by Whirlpool, or get the tech sheet out and do them yourself. Based on the part list, the possible parts are well under $500 so you may be able to fix it yourself and send the tech packing. I usually support independent servicers, but I don't like it when they leave customers with bad answers and wondering what now. It makes the rest of us professional technicians look bad.

    Thanks for the reply Brian. I don't know how far the tech went with his troubleshooting as I was offsite. Unfortunately he did not leave the old part here. I will try to get the old part in hand and run through the diagnostic checks myself. The basket turns easily by hand. I've been googling these cabrio error codes and there seem to be a lot of problems with these machines. I guess a g-note doesn't buy much of a machine anymore....
    As before, comments or suggestions are welcomed.

    They are a very good machine as they are based on the Fisher & Paykel design, but Whirlpool licensed it and what I call 'Americanized' it which basically made it double the cost and now it seems to have double the failures. They have been prone to F51 errors as this was a supplier problem that was fixed early on, but it did occur an most of the units at one time or another. The other problem of late is a rust issue under the top panel that is the result of excessive detergent usage. An updated tub ring was created to combat this issue (I wrote about it in a post on my blog) that seems to work better, but many of them are developing rust that starts to migrate down the side. But the rest of the unit is pure F&P which has turned out to be a very good product. Hope you get the part back and can take a look at it yourself. It is worth repairing, but no sense in wasting money doing it.

    Here is the latest. I ran the washer through a manual diagnostic test. The RPS installed by the tech was working fine, blinky lights when the tub was spun by hand. I wish I had the old RPS to test but the tech took it with him. I then set the lid lock and tried to spin the tub and got the F50, motor stalled code. You are right Brian, the F50 code isn't about the RPS it's indicative of a failed controller. I continued my checks and verified that the motor stator windings were OK, 30 ohms phase to phase. The wiring between the controller and the RPS and motor was good. I repowered the washer and started another manual diagnostic session. This time I was looking for output voltage from the controller to the BPM(Brushless Permanent magnet Motor). My older Fluke 87-3 is not really a good meter for troubleshooting VFD/VSD drives but it should see a changing output voltage. I didn't see any voltage from the controller to the motor. So now I need a new controller. The tech told me about $150 for the part, old p/n W10130544 new p/n W10189966, plus shipping.
    The tech's repair quote was for $347.50 flat rate plus an $80.00 diagnostic charge plus $50 for overnite shipping of the part. The RPS kit was $84.73 leaving a balance of $262.77 for their flat rate labor. The tech's repair company says that they use the MASPG blue book for their quotes. This flat rate figure seems over inflated to me. The service call was during normal weekday hours. Can anyone confirm the MASPG rate for what was diagnosed as a RPS replacement service call?

    One last bit for now: The service tech left one of his tools behind when he left. I gave him a friendly call today to let him know it was here and remind him that I want the old RPS. Maybe I'll get the old RPS after all....

    I am not sure about the MASPG rates as I don't use them, but those figures seem rather high given the difficulty of the repair. Based on your checks, it sounds like you are going in the right direction. The old number that starts with 'W' has been updated to W10189966

    Here's the latest... I fired the repair service but agreed to pay the charges for the service call and the part that I probably didn't need. Last Friday night I sent a happy-gram to Whirlpool.com and they responded back...

    Update: I received the controller board on Thursday. I changed it out without any trouble. I put the washer in manual diagnostic mode and the new board drove the motor to spinning. I made some points with the wife! Unfortunately the washer had a pretty good vibration at higher spin speeds, but removing the BPM rotor and re-indexing it to the motor shaft took care of the vibration. Whirlpool says that they want to help, so I've sent all my receipts off to their customer service group. We'll see what happens.
    BTW. I am impressed that they can put a little variable frequency motor drive on a controller board and make it so cheap. I guess they occassionally fail, but still its pretty good tech-stuff for a washing machine. I wish that I could troubleshoot and repair the board....

    Default Cabrio F50 Wrap Up

    We got a check from Whirlpool. They covered the cost of the RPS kit that we didn't need and part of the shipping. Beats a stick in the eye! Thanks Whirlpool.
