HWH jack manifold on Allegro Bay

[NoSnowInAZ]

Does anyone know where the manifold for the HWH series 200 jack system is located on a 2002 Tiffin Allegro Bay?
Problem: one jack is retracting slightly (not all the way). Have been told to find the valve for that jack which might be located at the manifold.
Someone also said I could be the solenoid for that jack.
Any ideas? Nearest tech is $300 in travel charge away.
Thanks!
BTW: had an accident two years ago in which done of the hydraulic system was replaced.

there is a kit you can order. the part number is RAP1635. this is a plunger and guide kit. it has four plungers in the kit.
those is the needles of the valves. this is not guaranteed to fix your problem, since the seat of the valve might be damaged.
you can remove the whole joystick assembly, send it in to be repaired if you want.
contact hwh by email for a rga.

It looks as though my response and Doug's response were posted at the same time. Sorry 'bout that.
Glad to get the solution. Would love to find access to a video on how to check the valves.
Thank you for your assistance.

as doug explained, the joystick assembly is the manifold.
the 200 hwh system had the valves built into the joystick assembly. that is the so called manifold. if you download a service manual for your system, you can see how the valves are incorporated into the assembly.

Thanjs

The question was ANSWERED by my post above your last response. Doug

A 200 system has NO manifold. The 100 (4 lever) and the 200(single lever Joystick), the Joystick control IS the manifold and there is a needle valve in the Joystick for each jack. So, if one jack slightly retracts and you are POSITIVE there are no external fluid leaks, then the usually course if to R&R the Joystick which includes the needle valves. But, you can remove the top stick cover and you will see each valve top and you can remove the offending valve hoping that there is some trash that is causing the bypass leakage. BUT, that is rarely the case, your valves are just worn out. Go to HWH's website and look up the 200 system manual and it will show a good detailed drawing and troubleshooting for it. Doug

Had the same problem.
Lower the jacks and as HWH recommends, spray with wd40 then try to retract. If so, use WD-40 to Clean the shafts about every other use.

Thanks for the response but the one jack retracts when I don't want it to - they all retract fine when I want them to

I would think that the Jack in question needs New Springs !

Can You lever it up ? Or can it be jacked up easily?

If it can be pushed easily into the retracted position a new set of Springs should cure the problem.

Been there done that!

BTW : tech at tiffin couldn't even tell me if it has a manifold. Not happy
