Product review (4 stars): Good: - It fixed the error code - It ...
I have a Whirlpool wtw6400sw2 that developped the F1 error code.

Good:
- It fixed the error code
- It changed the cycles somehow and seems to be quiter when filling the tub than before
- It wasn't to much trouble to replace, as it's mounted on the top back of the machine. Did require an unusual screwdriver head to remove the old one and put on the new one.

Bad:
- Loads with large items (like lots of towels or a blanket) seem to get themselves made into a ball and bang the machine around (then the machine stops until you untangle the load) a lot more than before. It wasn't perfect before, but I just washed several blankets I use on my bed one at a time and every one of them tangled themselves up into a ball and started thunking the machine around partway through the cycle before the machine shut itself down. I did a max capacity load of towels and there seems to be more of the same thing with those to. I don't remember having this issue before to this extent.

Bottom line - if your only issue is the F2 error code, this is probably worth it. If you have any other issues to fix on the washer it's probably best to buy a new machine.
