P046-UK_5.jpgIf you turn on the pump and hear clicking, or it runs on only one direction you're going to have to replace parts on your pump.

The question is which part? Use this guide to troubleshoot a hydraulic pump. If your pump isn't working it could be the motor, solenoid, coil, or a combination.

Get your pump up and running with the PIERCE troubleshooting and hydraulic pump testing guide. Find common issues accompanied by step-by-step instructions on testing the pump's solenoid, coil, and motor.

Symptom: Pump only runs in one direction. It could be the remote or coil.

For instructions on testing your coil read our article "How do I Test a Coil?"

Symptom: Pump does not run at all. It could be motor or solenoid or power to the pump

For instructions on testing your solenoid read our article "How to Test your Pump Solenoid"

Symptom: Pump motor doesn’t turn and you hear a click. It could be your motor or solenoid. The only way to diagnose the motor is to test it.

For instructions on how to test your hydraulic pump motor read our articles:

"How to Test a Single Post Hydraulic Pump Motor."

These instructions will get you to the next step of fixing your hydraulic pump.
