I have a Kenmore Elite front load washer/dryer that are stacked. The washer goes through the sequence of steps to wash a load of clothes, but when it gets to the spin cycle, it begins to beep and alert and blinks HF on the screen. If I try to cancel and start it again, you can hear water begin to go into the washer, then it errors out again and the same code shows on the screen again. I cannot find the owners manual for troubleshooting and don't know how to reset it. Please Help!
