You have a bad check valve which is part of the valve. Replace it.
agreed. we had hydraulic slides and jacks on a previous motorhome. for each slide and pair of jacks there were two solenoid valves.. in/out and up/down. you likely have a leaky "out" valve on your slide.
If it would be more convenient you could even add another check valve in line. In other words, if the check valve is part of another component just add another. Can't hurt.
Can't do that on HWH systems. The solenoid is NOT a Check Valve. It just opens and closes as fluid has to run BOTH ways. Doug
