tmw188 Posted February 27, 2023 Share Posted February 27, 2023 (edited) I’m posting for a friend to see if he can get some answers on his slides drifting in. It is a HWH controller. I believe HWH told him it was probably the Solenoids. Below is his explanation of the issue. Both rear bed room slides Rv stored indoors, connected to 50-amp service After extending slides fully out, within 6-8 hrs slides will gradually move in, passenger side more 10-15 inches than drivers side 8-12 inches. On occasion, double those numbers. Always both slides. Edited February 27, 2023 by tmw188 wording Link to comment Share on other sites More sharing options...
Donflem Posted February 27, 2023 Share Posted February 27, 2023 I had that happen and it was a solenoid. Link to comment Share on other sites More sharing options...
tmw188 Posted February 27, 2023 Author Share Posted February 27, 2023 So are these hydraulic, electric wouldn’t drift in? He thought his were hydraulic but I didn’t think the bedroom slides would be? Link to comment Share on other sites More sharing options...
Ivylog Posted February 27, 2023 Share Posted February 27, 2023 I would hold the switch on for several seconds after the slide stops moving so hopefully the debris is moved from the valve. My 08 bed is hydraulic. Link to comment Share on other sites More sharing options...
Jdw12345 Posted February 28, 2023 Share Posted February 28, 2023 My 05 Monaco Dynasty is hydraulic on the passenger side and electric on the driver side. Link to comment Share on other sites More sharing options...

Thank you for that info, I will tell him, he is in AR I am in FL. I’ve been passing along all replies to him. This morning he said his passenger BR slide has moved in about 1” and the drivers slide has not. Edited February 28, 2023 by tmw188 Link to comment Share on other sites More sharing options...
Solution Old Dog Posted March 1, 2023 Solution Share Posted March 1, 2023 The problem is caused by dirt or contamination getting between the needle and seat of the soleniod vavle allowing a slow leak by. In addition to running the pump in both directions, first drop as largest rare earth magnet that will fit down into the hydraulic tank. It picks up the praticulant before it gets in the needle valves. Don't run the pump more then 15 seconds in a two minute period to prevent over heating the motor. In case you have replace a soleniod vavle, they go for about $400 and you just unplug it and thread it off. Hard part is relieving the pressure before removal. On my type of slide if it creeps in the it's extend soleniod for the slide. Slides are numbered g for 1 - Driverside front, counterclockwise to 2, 3, 4. And generator HWH has instructions for identifying soleniods. Slideouts and bleeding procedure. CLEAN EVERYTHING BEFORE WORKING ON THE HYDRAULIC SYSTEM or all the old dirt and oil will get in there. Engine scrubber and a toilet brush work good. Hope the helps Link to comment Share on other sites More sharing options...
tmw188 Posted March 1, 2023 Author Share Posted March 1, 2023 Thanks Old Dog for that explanation and suggestions I will pass it on, and believe too it is the solenoid and with this additional info he should have enough to pursue it and get it repaired.
