F1 Error Code Fixed for Free
I also was receiving an F1 code on my Whirlpool Cabrio washer. I took the advice posted and called Whirlpool Customer Support 866-698-2538. The washer was purchased 4 years ago and off of warrranty as far as I know. They contacted an appliance repair company, set up an appointment and it was fixed for free today. They replaced the control board. Do make this call if you are experiencing the same issue. They can tell you if it can be fixed for free or not. Good Luck.
