Troubleshooting Dump Insert Performance: Common Issues & Fixes


An EZ-Dumper® insert is built to last. With rugged steel or stainless construction and a hydraulic lift rated for 6,000 lbs, it’s engineered for years of dependable service. But like any hard-working equipment, issues can arise over time. From electrical problems to slow lifting performance, knowing how to troubleshoot your dump insert helps you get back on the job quickly.


This guide explores the most common dump insert issues, what causes them, and practical solutions you can use. We’ll also cover when it’s time to contact your authorized EZ-Dumper® dealer for parts or professional service.

Why Troubleshooting Matters

When your insert isn’t working as expected, it can halt productivity. Landscapers can’t afford downtime in spring, snow removal crews need reliability during storms, and contractors lose money every hour equipment sits idle. Many issues, however, are simple to identify and resolve. By understanding how the hydraulic, electrical, and structural systems work together, operators can often restore performance with just a few checks.

The Three Key Systems

Every EZ-Dumper® insert relies on three systems:


  • Hydraulic system powered by the Monarch pump
  • Electrical system connected to your truck battery
  • Structural components like pivots, bed, and tailgate


Most issues fall into one of these areas. Identifying the root cause is the first step to an effective fix.

Common Problems and Fixes

Common Problems and FixesHere are the most frequent performance issues owners encounter, along with likely causes and solutions:

Problem Likely Cause Fix
Insert won’t lift Low battery charge, faulty wiring, or pump issue Check truck battery, clean terminals, inspect wiring to pump
Slow lifting or lowering Low hydraulic fluid, worn seals, or clogged lines Top off fluid, inspect for leaks, replace seals if needed
Insert won’t lower smoothly Air in hydraulic system or valve issue Bleed system, inspect pump and valves
Uneven dumping Pivot points dry or obstructed Grease fittings, clear debris from under bed
Tailgate not opening properly Latch or hinge jammed, bent hardware Inspect and clean latch, replace damaged parts
Electrical remote not working Loose wiring or corroded connection Reconnect wiring, clean contacts, replace if necessary
Excessive rust on steel insert Coating damaged, exposure to salt or moisture Clean, repaint with rust-inhibiting paint, consider stainless model

These fixes address the majority of common issues. More complex failures should be diagnosed by an authorized dealer.

Hydraulic Troubleshooting

Hydraulics are the heart of every dump insert. If the bed is moving slowly or not at all, start with the hydraulic fluid level. Low fluid can cause sluggish performance, while dirty or contaminated fluid may clog valves. Regularly check the reservoir, replace fluid on schedule, and keep an eye out for leaks around hoses or fittings.


Seals and cylinders also play a role. If you notice fluid seeping or the insert fails to hold its raised position, a worn seal may be the cause. Replacing seals promptly prevents further wear on the hydraulic pump.

Electrical Troubleshooting

Because EZ-Dumper® inserts run off your truck’s 12V battery, electrical issues can stop performance instantly. If the insert doesn’t respond to the remote, check the simplest point first: the battery charge. Weak batteries often cause sluggish or failed lifts.


Next, inspect the wiring between your truck and the hydraulic pump. Corroded terminals or loose connections are common culprits. Cleaning terminals with a wire brush and tightening clamps often resolves these problems. For persistent issues, a dealer can test the wiring harness and replace damaged components.

Structural Troubleshooting

The insert’s steel or stainless construction is designed for durability, but high use and harsh materials can still cause wear. Uneven dumping may signal dry pivots easily solved by applying grease through the insert’s built-in fittings. A tailgate that won’t open or close smoothly could indicate bent hardware or debris buildup. Cleaning, lubricating, or replacing worn parts keeps the system operating as intended.


For steel inserts, surface rust may appear if the powder coating is damaged. Treating affected areas early with rust-inhibiting paint prevents further spread. Stainless steel models resist corrosion naturally but still benefit from regular cleaning, especially after exposure to road salt.

When to Contact a Dealer

While many issues can be resolved with routine checks, some situations require professional service. If the pump makes unusual noises, if hydraulic performance doesn’t improve after topping fluid, or if electrical issues persist despite cleaning connections, it’s time to call your dealer.


Authorized dealers stock OEM EZ-Dumper® parts and provide service that keeps your insert performing at its best. Trying to force repairs without the right expertise can cause more damage or void your warranty.
