HWH Levelling jack not extending

Problem found, it was quite simple, just replace the fuse. Connection must have gotten wet, poor location right be hind the grill. Should be some kind of deflector installed, but that may cut air flow to the engine. Will spray to water proof a little better.

Thx for the tips, had not idea there were fuses for each solenoid.

Doug,
I'll try your suggestions, it does appear that the red indicator light for the LF jack in the control box is out which might indicate a blown fuse. Haven't removed the cover yet, too windy here with some dust blowing, so it may be a few days. I'll post when problem is found. THX Art

If your HWH control box and solenoids are easily accessible, swap the solenoid from one of the other positions with the left front solenoid. If the problem follows the solenoid, you have isolated the problem.

As Bill/Diana suggested, download the manual and trouble shooting guide for your system and make good use of them in trouble shooting your situation too.

Do NOT swap solenoids. The o rings are damaged when pulling the solenoids. ALL you have to do is manually OPEN the bad jack solenoid and activate the pump. IF the jack extends your manual operation is OK. Then connect a voltmeter to the supply 2 wire harness to that solenoid. With the pump activated you should have 12 volts. If NOT, then you have either that solenoid fuse blown or a wiring problem. IF you DO have 12 volts and the jack extends with it manually open, your solenoid is BAD. Replace it. Doug

Jacks are HWH brand. I have checked the fluid level.
Question: is the fluid level checked with the dip stick screwed all the way down or just sitting on top?
Thx Art

Click here to view various HWH manuals. Find your model number and then you can read all sorts of important information.

Hope this helps.

no expert on Itascas but my Lippert jacks were acting up because the fluid was low. It uses any automatic transmission fluid.
Hopefully you can search here or goggle your model and see what brand of jack is used or find it in your manual.
