Most Common Reasons Of Dewalt Pressure Washer Pump Not Working

Most Common Reasons Of Dewalt Pressure Washer Pump Not Working

1. No Water Flow

Cause:
The most common reason for a Dewalt pressure washer pump not working is no water flow. This can be caused by a number of things, including:

A blocked inlet filter:
The inlet filter is located at the front of the pressure washer and prevents dirt and debris from entering the pump. If the filter is clogged, it will restrict water flow and cause the pump to overheat.

A faulty water inlet valve:
The water inlet valve controls the flow of water into the pump. If the valve is stuck open or closed, it will prevent water from flowing into the pump and cause the pump to overheat.

A faulty pressure switch:
The pressure switch controls the flow of water to the pump. If the switch is faulty, it will not allow the pump to build pressure and the pump will not work.

Solution:
To fix a no water flow problem, you will need to identify the cause of the problem and take the necessary steps to fix it.

If the inlet filter is clogged, remove the filter and clean it with a brush or a garden hose:

2. Low Pressure

Cause:
Another common problem with Dewalt pressure washers is low pressure. This can be caused by a number of things, including:

A clogged outlet filter:
The outlet filter is located at the back of the pressure washer and prevents dirt and debris from entering the spray gun. If the filter is clogged, it will restrict water flow and cause the pressure to drop.

A faulty pressure regulator:
The pressure regulator controls the pressure of the water coming out of the spray gun. If the regulator is faulty, it will not allow the pressure to build up and the pressure will drop.

A faulty pump:
If the pump is damaged or worn out, it will not be able to generate enough pressure.

Solution:
To fix a low pressure problem, you will need to identify the cause of the problem and take the necessary steps to fix it.
