This unit has a F-51 error code. I took the inner basket out and found kids socks and cleared them, replaced the RPS and it still gives the F-51 code and doesn't operate correctly. The tub spins freely and the owners haven't complained about bearing noise. I ordered a main board and promised the customer that the new board will fix the problem.
How do test whether its the RPS vs the Board and do you think the new board will fix it? Thanks.
