I bought this washer from the previous owner where i was told it had been used less than a year and was functioning as if brand new, i turned it on prior to purchasing it and did not have any suspician that there was a problem. When i got it home and tried to use the washer, it only displayed f35 error code. After checking all connections as advised, i replaced the pressure switch; however, still keep getting the f35 code. please advise
