If you are experiencing problems with your HWH leveling system, don’t worry – you’re not alone.
Many RVers have found themselves in the same situation, and luckily, there is a solution.
This article will provide a complete guide on troubleshooting your HWH leveling system.
What Is HWH Leveling System?
The HWH leveling system is a hydraulic-powered leveling system used in recreational vehicles. It comprises two main components – the leveling jacks and the control unit.
The leveling jacks raise and lower the RV while the control unit activates and deactivates the system.
How Does HWH Leveling System Work?
The HWH leveling system uses hydraulic pressure to raise and lower the RV.
When the system is activated, the control unit sends a signal to the leveling jacks, which causes them to extend or retract.
It raises or lowers the RV, depending on how they are extended.
How Do I Troubleshoot My HWH Leveling System?
If you are experiencing problems with your HWH leveling system, you can do a few things to troubleshoot it.
Simple Tests Must Be Performed
Before you start troubleshooting, there are some simple tests that you must perform.
These tests will help you determine if the problem is with the leveling jacks or the control unit.
Test the leveling jacks by manually extending and retracting them. If they extend and retract correctly, the problem is with the control unit.
Test the control unit by turning it on and off. If it turns on and off correctly, the problem is with the leveling jacks.
Leveling Jacks Are Not Extending/Retracting
If the leveling jacks do not extend or retract when you activate the HWH leveling system, you can do a few things to troubleshoot.
