Its says f51 error - Whirlpool Cabrio WTW6600SBT Top Load Washer

F51 error code is a motor rotor position sensor failure or a lower harness problem

Cabrio F51 Fault (Stored Fault Code F51) The Cabrio's F51 fault code flashes on the washing machine's display when there is a motor rotor position sensor (RPS) failure.
Check for good contact at the control Board and at the RPS. Sometimes disconnecting and reconnecting the RPS plug connection several times will clean off corrosion that may be affecting the contacts.

Here is an earlier Fixya answer addressing the query:

Whirlpool cabrio error code f51 what does it mean

Sensor is item 20 below. Clean it.

On some machines the F51 is a slow or long drain error. Possibly a clogged filter in the drain pump or a bad pump. You did not provide enough information for me to offer any more help. I do not know the washer type, manufacturer, age, or model.

Hi Craig,

Just saw this post come up among F51 error codes (as it will show previously posted and answered questions ) and wanted to add some info I have regarding this exact issue you may or may not already have, no harm in posting either way.

The F51 typically indicates a failed "RPS" has been detecected...but it can be the result of other issues...just for future reference and if anyone has not come accross this before.

The scenario you describe is usually associated with a item stuck under the tub or a loose stator or a faulty "RPS" device or connection at the "RPS"...but I don't know if you checked that yet or if you know how, thus the error F51.

**The repair tip below is directly from Whirlpool**

F51 is usually associated with the rotor and stator/RPS assembly and quiet often it is initiated due to a loose rotor or bad RPS...I'd start by checking the bolt.

There is a repair tip regarding this which suggest checking the wires to the RPS and then the rotor, while insuring the center bolt is really tight via applying some "lock tight".

I actually see a lot of these and most times it's a loose rotor bolt, that is where I always start my diagnosis. Here's an exert from my files directly from Whirlpool...



You may want to check the rotor, I've seen the center bolt become extremely loose, thus causing the F51 error, this is where and what to look for shown below...


...but either way that should help out with the repairs and good luck.

Macmarkus :)
