I have a HWH 2000 series joy stick leveling system and 2 slides. When using the rocker switch in the BR or the switch at the pump to activate the Dewald pump it does NOT shut off when u release the rocker switch at either location. When the room is fully extended or retracted it randomly does not shut off either. It will just run on for 15-20 seconds or more and then shut off. I walked away after it shut down and all of a sudden the pump came on then shut off and cycled like this several more times with no one activating the rocker switches. I am not running to the engine compartment to disconnect the engine battery in an effort to prevent this from happening while I am away from the coach. I am thinking a relay must be causing the problem but having not unmounted the assy from the compartment do not see one. Have searched the HWH site to no avail. Left a message and was told the technicians are several WEEKS behind in answering tech inquiries. I am afraid I am going to destroy a pump/motor if this keeps up. Any advise would be appreciated. Joe
