Our rv washer/dryer model mj9900 was installed by the dealer as an incentive to buy our rv. I believe we were given a faulty unit as it never worked. We took it back once and they said that they fixed it but it never worked. We gave up. Now I am writing to see if it can be resurrected or should I just take it out. It is 6 or 7 years old. It just washed a load of laundry but I had to manually turn the knob for each cycle. It will not dry. We never received a manual and the dealer is out of business.
