Blocked Hose:

A blocked hose due to massive usage over a long time. Cleaning out any blockages from the hose can quickly sort out the issue for you.

Half tap issue:

The water might not be turned on at full force, or your tap supplies less water than required for the pressure washer to run at total capacity.

Inlet Filter:

The water inlet filter might be blocked by debris and fungus, which must be cleaned. Clearing out any debris from the water filter will be enough to increase the pressure.

The trigger gun and nozzle might be blocked from inside, so they should be clean to operate the pressure washer at full force.

You would have to open your pressure washer and have a detailed check to proceed further. It is always recommended to call an expert for this task.

However, you can do it by yourself if you know how machines work. Ensure that the pressure washer is turned off and disconnected from the power supply.

There are possibilities that a pressure washer is fluctuating from high to low pressure due to the air trapped in the pump.

Afterward, turn on the water source and allow the water to pass through the pump for at least 30 seconds.

Reconnect all the components and try using the machine again.
