A pressure washer is a powerful tool that can be used for a variety of tasks, from cleaning driveways and sidewalks to removing paint from walls. However, when the pump on a pressure washer stops working, it can be a major inconvenience. Not only can it prevent you from completing your projects, but it can also be dangerous if you attempt to use the pressure washer without the pump working properly.

This guide will help you troubleshoot the common issue of a pressure washer pump not working. By following the steps in this guide, you can quickly diagnose and resolve the problem, so you can get back to using your pressure washer as soon as possible.

Most Common Reasons Pump Not Working On Pressure Washer

Most Common Reasons

1. No Water Inlet

The most common reason for a pressure washer pump not working is that there is no water flowing into the pump. This can be caused by a number of things, including:

A kinked or blocked hose
A closed water valve
A faulty water inlet valve
A clogged water filter

2. Clogged Inlet Screen

The inlet screen on a pressure washer pump prevents dirt and debris from entering the pump. If this screen becomes clogged, it can restrict the flow of water to the pump, causing it to overheat and malfunction.

3. Faulty Pressure Switch

The pressure switch on a pressure washer controls the flow of water to the pump. If the pressure switch is faulty, it can cause the pump to overheat and malfunction.

4. Blocked Discharge Hose

The discharge hose on a pressure washer carries the water from the pump to the nozzle. If this hose becomes blocked, it can prevent the water from flowing out of the pump, causing it to overheat and malfunction.

5. Faulty Pump

In rare cases, the pump itself may be faulty. This can be caused by a number of things, including:

A worn-out impeller
A damaged shaft
A faulty valve

If you suspect that the pump is faulty, it should be replaced by a qualified technician.

How to Troubleshoot: Pump Not Working on Pressure Washer

Your pressure washer is a valuable tool for cleaning your home, car, and other outdoor surfaces. But what happens when the pump stops working? This can be a frustrating problem, but it’s usually easy to fix. In this blog post, we’ll walk you through the steps of troubleshooting a pressure washer pump that’s not working.

Step 1: Check the power

The first thing you need to do is check to make sure that the pressure washer is plugged in and turned on. If it’s not, plug it in and turn it on.

Step 2: Check the water supply

Next, you need to check to make sure that there’s water flowing to the pressure washer. To do this, turn on the water supply to the pressure washer and check to see if water is flowing out of the hose. If no water is flowing, there may be a problem with the water supply line.

Step 3: Check the pressure switch

The pressure switch is a valve that controls the flow of water to the pump. If the pressure switch is stuck open, it will prevent the pump from building up pressure. To check the pressure switch, turn on the pressure washer and listen for the sound of the pump. If you don’t hear the pump running, the pressure switch may be stuck open.

To fix a stuck open pressure switch, you can try to gently pry it open with a screwdriver. If that doesn’t work, you may need to replace the pressure switch.

Step 4: Check the pump

If the pressure switch is not stuck open, the next thing you need to check is the pump itself. To do this, remove the air filter from the pump and look inside. If you see any debris or damage, the pump may need to be repaired or replaced.

Step 5: Check the hoses

Finally, you need to check the hoses to make sure that they’re not kinked or damaged. If the hoses are kinked or damaged, they will prevent the pressure washer from working properly.

Conclusion

By following these steps, you can troubleshoot a pressure washer pump that’s not working. If you’re unable to fix the problem yourself, you can always take your pressure washer to a qualified repair shop.
