Customer Question

hey John
my name is Willy
I have a duet front load model #WFW8300SW03 washer
f21,f34, SD, f01
Pump is good, lines are clear filter clean.
it makes one load complete cycle, than when second wash is started, the F's start appearing.
I manually drain tank thru pump filter to complete cycle.
always stops on rinse/spin or drain spin.
ordered a new water level pressure switch and will install it tomorrow. Pump also seems quite hot now.
What else could it be or could I do?

So the pressure switch could cause some of these issues, but usually the pressure switch isn't the problem. The only thing that can cause the F01 is the main control board also known as the CCU. The main control board is part number W10525351 and below is a link to the part.

This is the only part that would cause all of your errors so unless you have 2 issues, the board is going to be your faulty part you'd want to order and replace. It's mounted to the right side panel above the tub and can be seen if you remove the top panel of the washer.
