Here's what the "F" code means.
It means primary control failure and to resolve this you'll have to replace the machine control assembly. This error should be fixed by whirlpool as its a common issue with whirlpool Cabrio washers, you can call 1-800-253-1301 whirlpool will send a tech. to fix it and pay for the part.
I assume the labor will not be covered.
how much is the part?
What is your model number?
Thanks. This is the part here.
The cost is $173.35
