My bet is you blew a fuse on the control board. Finding that can be
fun too. I had one under the dash and the one I've got now is mounted
to the ceiling of the storage compartment and protected with a sliding
plexiglass panel. If yours is the automatic self leveling type system
that is probably where yours is too, since they mount the level sensor
in the same area also protected by the same panel. Mine wasn't even
plugged into the control board when I got it home.

Take care and Happy Campin...

The control board thingie with the plexiglass and the tank are behind the slide. We checked all the fuses there and they are good. If there is another place for a fuse, I don't know where. The fluid was checked when we put it on the pad for the winter. I can't imagine it having disappeared. The control pad inside the coach lights up and the dinger dings on the dashboard.

There are fuses all over the place like under the dash and inside the motor place in the front. How can I possibly know which one of these fuses would be related to the jacks?

Hi Janet,
Did the jacks retract when you manually turned the Tee Handles on the
solenoids? If not then you may have a stuck shuttle valve. That valve
switches back and forth between pressure and return flow and controls
the flow for all other solenoids. If that is the case, and you cannot
manually retract the jacks, you need to get in touch with HWH for sure.
It should still be under warranty. If not it's CSP time again... But
it's not a real huge job. If you take it out to them they will likely
fix it for free.

haven't tried yet. We decided to wait until Mondy and give HWH another call. I may try the Ts but I'm wearing a nice shirt today and didn't want to get it all dirty under the motorhome. Barry wasn't up to crawling under it either. CSP won't make a service call. They only pay for service calls for fifth wheels. If I need that I'll have to call Coachnet. Do you think Coachnet would be able to fix them?

Where to find the other fuse. That fuse is probably ok if the panel
lights but here is how to find it, you never know. Find your books from
Tiffin. In there should be one small book named Tiffin Motor Homes
Electrical Schematics or some such. Mine is a small book, maybe 5 X 7.
In it, will be schematics for all the electrical systems, both 12V and
120V. Look in the index and find Battery Circuit Regular Gas. If you
look at that page you will see the HWH pump and motor. The pump and
motor is wired directly from the house batteries as shown in the
drawing. I don't remember for sure and it's dark out so I'm not going
to look :), but the cable I believe goes to a solenoid on the
pump/motor. That solenoid is controlled by the control box/board
through a 5 AMP fuse. The wire going to the solenoid comes out of the
relay panel on the control/box next to the fuses. On the big wire going
from the batteries to the pump/motor you should have 12V on that wire
all the time. You should only have 12V on the wire coming from the
control box and going to the solenoid on the pump when you extend the
jacks, that will make the pump run.

Woa! I appreciate the help, but you must remember you are talking to the electrically challenged. I have a little box thingie with wires in it that is supposed to check wires. Is that what I use?

In the section marked Extra Fuse Panel look at the drawing for Extra
Fuse Panel for Ignition and you will see a fuse marked JACKS. That fuse
must be good in order for the system to work. In my coach the Extra
Fuse Panel for Ignition is accessed in a small compartment on the
outside of the coach directly under the driver, but mine is a diesel.
In your gas coach I don't know where they put it. But that's the panel
you have to find. There should be two panels close together. On the
panels you should find the fuses marked for the items listed in the
drawing in the book. Should be a fuse for your camera, your power
mirrors and jacks on that fuse block, maybe others too.

I'll try to find the diagram and the fuses

If that fuse is OK, and the fuses on the HWH board are OK, I think
there are 7 of them on the 610 system, and you have power going from the
battery to the solenoid on the motor/pump then the jacks should extend
when the button is pushed.

they are extended. I want them to retract. They won't retract.

For them to retract you press the retract button and that switches the
four solenoids and the fluid is forced back into the tank by the springs
on the jacks feet. Each jack has it's own fuse on the control box and
there is a master dump fuse on the control box. If the solenoids are
not switching but the jacks retract manually you have a problem with the
control box or the wiring. If they will always extend but won't
retract, my guess is the control box. BTDT as they say.

I don't have a "retract" button. There is a "store" button that does the retracting.
Something you may not know. You should never use the OFF button on the
control panel when storing the jacks, nor turn the key off. It takes a
long time, several minutes for the store process to complete. If you
stop it without letting it complete on it's own it can cause problems.
Both with the jacks not being completely retracted and in the
electronics. At least that's what I was told, by a HWH tech several
years ago. I start the store process then go and finish up everything
outside. If it still hasn't completed storing when I get ready to start
the engine, once I start the engine I hit the store button again. You
can drive as long as the green travel light is on even if it hasn't
finished storing.

We always keep it on "store" otherwise the dinger on the dash board goes off. The instructions say to keep it on "store" when traveling.

Probably a lot more then you wanted to know. But HWH is going to ask
you to check ALL the fuses, that means pulling each one and looking at
it and using a tester. You will be ahead of the game if you do that
before hand, plus you will impress the technician.... :)

Thanks again, Rich. I really appreciate all of the time and effort you have given to my problem.
