What a Lippert leveling system reset does

A Lippert leveling system reset clears error codes and restarts the control module that manages your RV's automatic leveling jacks. When your system displays an error message, won't respond to button commands, or gets stuck partway through leveling, a reset often fixes the problem without requiring a technician visit. The reset process takes a few minutes and uses controls you already have in your RV.

The system uses hydraulic jacks at each corner of your RV to level the vehicle when you're parked. The control module — a small computer box — tells those jacks when to extend or retract. If the module gets confused by a sensor glitch, power surge, or communication error, it stops responding. A reset tells the module to forget the error and start fresh.

Key Takeaways

  • A reset clears error codes from your Lippert control module and restores normal leveling function in most cases.
  • The most common reset method is to turn off the main power switch, wait 30 seconds, and turn it back on.
  • If your system has a dedicated reset button, pressing it for 10 to 15 seconds will perform a full reset without cutting power.
  • After a reset, test the leveling system on flat ground before relying on it to level your RV at a campsite.
  • If the same error returns when ready after a reset, the problem is likely a sensor or hydraulic issue that needs professional diagnosis.

Locating your control module and power switch

The Lippert control module is usually mounted inside a cabinet or under a bed in your RV — check your owner's manual for the exact location, as placement varies by model and year. The module is a rectangular box roughly the size of a car battery, with wiring connected to it. Near the module or elsewhere in your RV, you'll find the main power switch for the leveling system; this is often labeled "Leveling" or "Hydraulic" and may be a rocker switch or a breaker-style switch.

If you cannot find the module or switch, your owner's manual will show a wiring diagram with their locations. Many RV owners keep this manual in a cabinet near the driver's seat or in a storage compartment. If you've lost the manual, Lippert's website allows you to search by your RV's model and year, and many RV forums have users who can point you to the right location for your specific rig.

The standard reset procedure

Turn off the main power switch for the leveling system and leave it off for at least 30 seconds. This gives the control module time to discharge and clear its memory. After 30 seconds, turn the power switch back on. The module will restart, and any error codes stored in its memory will be erased.

Once power is restored, wait another 10 to 15 seconds before pressing any leveling buttons. The module needs a moment to initialize. Then press the "Level" or "Auto" button to test the system. The jacks should begin extending or retracting smoothly, and the control panel should display normal operation without error messages.

Using a dedicated reset button if your system has one

Some Lippert systems include a physical reset button on the control module itself. This button is usually red or black and may be recessed slightly into the module's face. If your system has one, you can use it instead of cutting power to the whole system.

Press and hold the reset button for 10 to 15 seconds, then release. The module will restart without losing power, which can be faster and safer than flipping the main switch. After releasing the button, wait 10 to 15 seconds for the module to reinitialize, then test the leveling system as you would after a power-based reset.

Testing the system after a reset

Before you rely on your leveling system at a campsite, test it on flat, level ground where a malfunction won't cause your RV to tip or shift. Park on a level surface, turn on the system, and press the "Level" or "Auto" button. Watch and listen as the jacks extend and retract. All four jacks should move smoothly, and the control panel should show no error codes.

If the system levels normally and the error is gone, the reset worked. If the same error code reappears when ready, or if one or more jacks don't move, the problem is likely a faulty sensor, a hydraulic leak, or a wiring issue — all of which require professional service. Do not attempt to level your RV at a campsite if the system is not functioning correctly, as an uneven RV can cause structural stress and safety hazards.

Common error codes and what they mean

Lippert systems display error codes as numbers or letters on the control panel. A code like "E1" or "E2" usually points to a sensor that isn't communicating with the module — often fixed by a reset. Codes related to pressure or hydraulic function (sometimes shown as "P" codes) suggest a leak or pump problem that a reset won't fix. Codes indicating a jack that won't move or moves too slowly may be a motor or valve issue.

Write down the exact error code before you reset, so you can tell a technician what you saw if the problem persists. If the code returns after a reset, that information helps the technician narrow down whether the issue is electrical, hydraulic, or mechanical.

When a reset won't solve the problem

A reset clears temporary glitches but cannot fix hardware failures. If your system won't respond to buttons at all, if one jack moves but others don't, or if you hear a grinding noise or smell hydraulic fluid, the problem is physical damage or a failing component. A reset will not restore function in these cases.

Similarly, if the error code returns within a few minutes of a successful reset, the underlying cause is still present. This pattern usually means a sensor is failing intermittently, a wire is loose, or the hydraulic system is losing pressure. At this point, contact an RV service center or Lippert's customer support line to arrange a professional inspection. Attempting further resets will only delay the repair.

Frequently Asked Questions

Will resetting my leveling system erase other RV settings?

No. The leveling system reset affects only the leveling control module, not your RV's other systems like the water heater, refrigerator, or slide-out controls. Those systems have their own separate power and control circuits.

How often can I safely reset the leveling system?

You can reset it as often as needed without damaging the module. However, if you find yourself resetting it multiple times per trip, that's a sign of a deeper problem that needs professional attention rather than repeated resets.

What if I can't find the power switch or reset button?

Check your RV's owner's manual first — it will show the exact location for your model. If you don't have the manual, contact Lippert customer support with your RV's year and model, or post the question in an RV forum with your RV's details. Other owners of the same model can usually point you to the right spot.

Can I reset the system while parked on uneven ground?

Yes, you can perform the reset itself on uneven ground. However, do not test the leveling function until you're on level ground, because testing on a slope may cause the jacks to move in unexpected ways or give you a false reading of whether the system is working correctly.

Should I reset the system before calling for service?

Yes. A reset is a safe first step and often solves the problem without a service call. If the error returns right away or the system still won't work after a reset, then contact a technician — you'll have already ruled out a straightforward glitch, which saves time and money.
