HWH 610 jack stuck in travel position

Last month we had a HWH 610 system installed on our Sunseeker class C motorhome. We are less than a week into our summer trip having used the leveling system maybe three or four times total and the front left jack is not descending into a vertical position with the other three. This one jack is stuck in the travel position. Images below.

I have left a message with the dealer but it is the weekend.

I've been searching online and found lots of threads about jacks being stuck DOWN but nothing about being stuck UP.

Any suggestions?

I cannot see the actuator mounting from your picture. In the position that you've taken the picture, the actuator is above the hyd cylinder - it connects to the spring wire that you can see mounted at the pivot point at the top of the hyd cylinder. This little actuator cylinder is responsible for pushing the leveler down and into the vertical position. The mounting point for the actuator has either broken or the actuator cylinder itself has failed.

In either case you still use this for the weekend or until you get it back to the installing dealer. As the other levelers are coming down use a large prybar or piece of wood of some sort to help flip this leveler to the vertical position and it will continue to operate normally.

Hello plate; sorry to hear about your problems with HWH jack.

I would check the electrical connections for the HWH. I would also use a volt meter and I would first check the voltage at working jack solenoid while it is extending. I would than check the voltage at the nonworking jack solenoid to see if it is getting power. If it is than it is possibly the solenoid. If no power it could be a connection or possibly the circuit board.

I hope this helps.

Do not auto level...it may not work anyway if it sees it now down.

Ours is old so may be different...

The kick down is a single circuit so all are on common pipe.

Likely broken mount or failed cylinder.

Hwh should be of help now during work week.

Have helper activate system while you observe from below to see and listen

spray some lube on the pivot point for that jack. there may be an buildup of paint in there. hwh dips the jacks rather than paint them. its an epa thing. can you swing it down by hand? if so, that the problem.

Thank you, azpete, that is doing the trick. It has taken a couple three sprays and wrestles and since only once has it stuck.

I tried today to see it stick, but it worked great. Watch here...

Thanks again for the great advice!
