Troubleshooting RV Leveling Jacks Won’t Extend

Now, it’s time to address the culprits behind the malfunctioning jack. Also, based on my experience, I will share some easy fixes with you. Let’s check them out:

Reason 01: Power Supply Issue

When using an automated system like HWH jacks, power gear supply problems can arise, leading to unresponsiveness or partial extension of the jacks. This is a safety feature to prevent mishaps during the lifting process. However, it has happened to me many times, and the good news is, there is an easy fix. First, I will guide you on how to identify this issue:

  • Push the power button and observe the jacks’ response.
  • Complete unresponsiveness signals a power supply issue.
  • Partial extension may indicate a different problem with the jacks.

If you detect any issue following this procedure, head to the below-guided steps.


Here’s what you need to do to fix the supply problem:

  • Step 1: Start by releasing air from HWH system as this helps depressurize the system, a necessary step in resetting the jacks.
  • Step 2: Afterward,hold down the auto-leveling button for 15 seconds as this will initiate the reset process quickly. Following this, allow a few minutes for the reset process to complete.
  • Step 3: As the reset process completes, attempt to use the HWH jacking system again. This will help you ensure that the system reboots and is ready for operation.

Reason 02: Mechanical Errors

Dealing with mechanical hiccups in any system is a common experience. Whether it’s due to routine wear and tear or factory mishaps, mechanical glitches are the primary cause behind HWH jacks thatwon’t extend. Identifying these issues is crucial, and if your jacks only extend partially or retract persistently after extension, it’s likely a mechanical error.

Reason 02: Mechanical Errors

A quick fix for mechanical errors is a system reset, which often resolves power supply and mechanical malfunctions causing extension issues. However, if the problem persists, seeking professional help might be necessary.

Moreover, keep in mind that these mechanical malfunctions are just a natural part of any machine’s life, and your RV’s leveling jacks are no exception.

Reason 03: Connector Malfunction

Dealing with mechanical errors, particularly connector malfunctions, in your HWH leveling system is a common challenge. The HWH system stores data about your RV’s dimensions to facilitate lifting, but occasional malfunctions can occur. So, if your HWH jacks only extend partially or keep retracting after extension, a mechanical error may be present.

The basic reason behind this often includes wear and tear or factory issues, making it difficult to extend the jacks. To overcome this issue, apply the fixes that I have outlined below based on my experience:


Here are a couple of easy fixes you should try:

  • First, inspect the wires inside your HWH jacks system for proper connections and any signs of damage.
  • If you find any wires to be loose, reattach them to the power source and if damaged, replace them.
