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.
- Check for debris or blockages in the leveling jacks. Remove any debris or blockages and try activating the system again.
- Check for power to the leveling jacks. If there is no power, check the fuse panel and ensure the fuse for the leveling jacks is not blown.
Control Unit Is Not Turning On
If the control unit is not turning on when you activate the HWH leveling system, you can do a few things to troubleshoot it.
- Check for power to the control unit. If the power does not come on, check the fuse panel for any open fuses and try resetting them.
If there is power to the leveling jack and control unit, but it is not turning on, there may be a problem with the motor or gearbox.
Examine Your Car
Before replacing any parts, it is good to visually inspect the leveling jacks and control unit.
It will help you determine if there is any apparent damage or malfunction.
If you find damage or malfunction, you may need to replace the leveling jacks or control unit.
However, if the problem is not apparent, you may be able to fix it by simply cleaning the parts or lubricating them.
Cleaning The Leveling Jacks And Control Unit
If you cannot find any apparent damage or malfunction, you may be able to fix the problem by simply cleaning the leveling jacks and control unit.
- Start by disconnecting the power to the HWH leveling system.
- Next, use a brush to clean any dirt, debris, or corrosion from the leveling jacks and control unit.
- Once you have cleaned the parts, reconnect the power and try activating the system again.
Lubricating the Leveling Jacks and Control Unit
If cleaning the leveling jacks and control unit does not fix the problem, you may need to lubricate them.
Get Help From Machine Instructions
If you are still having trouble troubleshooting the HWH leveling system, you may need help from the owner’s manual.
The owner’s manual will provide more detailed instructions on troubleshooting the system and replacing any parts that may malfunction.
If you cannot find the owner’s manual, you can usually find it online. Search for the make and model of your RV, followed by “owner’s manual.”
Try To Manually Retract Jack
When the leveling jacks are not retracting, you won’t be able to move the RV securely, and you’ll be stuck at your campground or RV park.
There are various reasons why an RV’s leveling jacks may not retract.
HWH systems are the most prevalent type of hydraulic leveling jack on RVs.
These systems usually come with manual control that allows you to pull the jacks back to get your RV to a repair shop.
It generally entails manually prying the jacks out using a tool.

If the HWH leveling system is not working and you have already checked for power and debris, you may want to retract the jack manually. You can do it with a ratchet strap.
- Loosen the port on the top of the jack motor.
- Remove the rubber plug.
- Next, attach the ratchet strap to the bolt and tighten it.
- Now, slowly retract the jack by turning the handle on the ratchet strap.
