I remember dealing with that exact issue when my machine started flashing F8 and E1 for no reason. I called the contact provided on https://whirlpool.pissedconsumer.com/customer-service.html and got through to a repair specialist who explained the codes were related to water flow sensors. They guided me step by step on how to clear the error manually before scheduling a maintenance visit. Having real guidance instead of guessing made all the difference in getting it running again.
