Troubleshooting Your EZ-Dumper® Insert: Common Problems and How to Fix Them

EZ-Dumper® inserts are built to perform under heavy workloads and tough conditions. Whether you’re hauling mulch, gravel, debris, or snow, each insert is engineered for long-term reliability. But over time, like any mechanical system, your insert may experience a hiccup a power issue, a weak lift, or a failure to operate at all.
If that sounds familiar, you’re not alone. Every hardworking unit will eventually require inspection or maintenance. The good news is that many common issues have straightforward solutions you can troubleshoot yourself safely and efficiently.
In this blog, we’ll walk through the most frequent dump insert problems and offer practical guidance for identifying and resolving the issue. We’ll also explain when it’s time to call your EZ-Dumper® dealer or a qualified service tech.
Start Here: Follow Safety First
Before beginning any inspection or troubleshooting, take the proper safety precautions. Always:
- Park on level ground
- Disconnect the truck battery if working on electrical components
- Use approved safety props before working under a raised bed
- Wear gloves and eye protection around hydraulic systems
Never attempt to bypass safety features or operate the insert with exposed wiring or leaking fluid. If you’re unsure at any point, stop and consult the EZ-Dumper® Owner’s Manual or your local dealer.
Problem #1: The Dump Insert Won’t Lift
One of the most common complaints is that the dump insert doesn’t raise when the remote button is pressed. Here are the areas to check first:
1. Battery Connection
EZ-Dumper® inserts operate using a 12V double-acting hydraulic pump powered by the truck battery. If the battery is weak, dead, or disconnected, the pump won’t function.
- Check that the battery is fully charged
- Inspect the terminals for corrosion or loose cables
- Verify the fuse or breaker in the power line is intact
2. Remote Control Switch
The handheld remote is used to control the “up” and “down” motion. If the switch is faulty, loose, or internally corroded, it may prevent operation.
- Confirm the remote is plugged in securely
- Inspect the cord for visible damage
- Replace the switch if it’s unresponsive despite power
3. Hydraulic Pump Motor
If power is reaching the pump but there’s no motor activity (no sound, no movement), the motor may be burned out or the internal solenoid could be faulty.
- Test for power at the motor terminals
- Listen for any motor noise when the switch is pressed
- Consult a dealer if you suspect internal pump damage
Problem #2: The Insert Lifts Slowly or Unevenly
If your dump bed lifts but feels weak or rises unevenly, it may be related to the hydraulic system.
1. Low Hydraulic Fluid
EZ-Dumper® systems require the right level of clean hydraulic fluid. If levels are low or the fluid is contaminated, lifting will be compromised.
- Check the fluid reservoir with the bed lowered
- Refill using the manufacturer-recommended fluid (per your Owner’s Manual)
- Look for signs of leaking around the cylinder or fittings
2. Air in the System
If you recently serviced the hydraulics or topped off the fluid, air pockets may remain in the lines.
- Cycle the dump bed fully up and down 2–3 times
- Listen for hissing or sputtering
- Recheck the fluid level and top off if needed
3. Worn or Damaged Cylinder
Hydraulic cylinders that are dented, pitted, or leaking can affect performance.
- Inspect the cylinder body and seals
- Check mounting points for movement or uneven force
- Contact a dealer if replacement is needed
Problem #3: The Insert Won’t Lower
If your insert lifts fine but won’t return to the down position, this may indicate an issue with the “power down” function or hydraulic restriction.
- Make sure the remote switch is functioning in both directions
- Check that the Monarch pump solenoids are responding correctly
- Ensure the hydraulic hoses are not kinked or obstructed
Some double-acting systems rely on solenoids to open the return valve. If this valve sticks, the fluid cannot flow back into the reservoir, preventing descent.
Problem #4: The Tailgate Won’t Open or Close
EZ-Dumper® inserts come standard with a removable, double-acting tailgate. If yours won’t swing open or is stuck closed:
- Check for debris or buildup near the hinges
- Inspect latch pins for wear or damage
- Confirm the tailgate is installed in the correct orientation (spreader vs. dump mode)
Rust or damage around the pivot points can restrict movement. Cleaning, lubrication, or part replacement may be needed depending on severity.
Problem #5: Unusual Noises or Jerky Movement
If you hear knocking, whining, or grinding during dump operation or if movement seems erratic don’t ignore it.
Possible causes include:
- Low or contaminated hydraulic fluid
- Loose cylinder mount bolts
- Air in the system
- Misalignment of the insert in the truck bed
Stop operation and inspect the unit thoroughly. Jerky or noisy operation can lead to component failure if not resolved quickly.
