Lippert electronic leveling system
I have a 2014 ACE 29.2 motorhome. The right front hydro hose blew out at the leveling jack. You could see that it was not fully seated before they crimped on the fitting. In any case I had a local ...

LCI systems need to be purged.
The basic purge procedure to bleed the LCI Hydraulic Systems is performed without the use of any tools. The system's own function purges the air from the hydraulic lines and cylinders by simply running the pump. These simple steps will apply to Hydraulic Landing Gear (HLG), Hydraulic Stabilizer Jacks (HSJ), Class A Motorized Vehicles Leveling Jacks (LJ) and Hydraulic Slideouts (S/O). 1. Start with all hydraulic components in the fully retracted position, meaning all jacks, landing gear stabilizers and slide outs brought back inside the coach as if it were ready to travel. 2. Find the hydraulic pump location and note the amount of fluid currently in the reservoir. The fluid level should be about 1/4” from the top of the reservoir and no more than 1/2” from the top. NOTE: When checking the fluid level after ensuring all hydraulic components are retracted, note if there are any bubbles, froth or foam on top of the fluid. This is an indication that air has been pushed back to the reservoir when the hydraulic components were retracted in the last cycle. Wait 15-20 minutes for the foam to dissipate before beginning the purge process. 3. If there is no froth or foam in the reservoir and the fluid is not within 1/2” of the top, fill the reservoir to within the level described in Step 2. 4. With the fluid level full and no foam in the reservoir, begin cycling the hydraulic system: CLASS A - Extend LJ fully, taking the coach off the tires. If the unit has hydraulic S/O, extend all S/O. Once all LJ and S/O are extended, immediately retract all S/O and then all LJ. Doug
