My Pressure Washer is leaking from the body of the machine

Quick Answer

If your pressure washer is leaking from the main body of the unit, this is usually caused by an internal seal failure or a crack in the housing. In many cases, it can also be due to a seal becoming dislodged around the motor or pump assembly, which allows water to escape from underneath the machine.

In most situations, this type of issue will require inspection and may result in a replacement unit.

Before You Start

Before checking the machine, make sure:

• The pressure washer is switched off and unplugged or battery removed
• The water supply is disconnected
• The trigger has been pulled to release any remaining pressure

Always:

• Place the machine on a dry, flat surface
• Avoid operating the unit if water is leaking from the base
• Keep electrical components away from water exposure

Important: Do not continue using the machine if water is leaking from the body, as this can indicate internal damage.

Common Causes of Body Leaks

Leaks from the main unit are typically caused by one of the following:

• A cracked internal housing or pump casing
• A displaced or damaged internal seal
• A seal failure around the motor or pump assembly
• Excess pressure damage caused by blockage or incorrect use

What You Should Check

If it is safe to do so, you can visually inspect:

1. The underside of the machine

Look for visible water pooling or dripping from vents or seams.

2. The housing seams

Check for cracks, gaps, or signs of separation in the casing.

3. Recent usage conditions

Consider whether:

• The machine was exposed to freezing temperatures
• It was used with blocked nozzles
• It was run without adequate water supply

These factors can increase internal pressure and cause seal failure.

Important Information

If water is leaking directly from the body of the machine:

• It is not typically a user-serviceable issue
• Internal seals or pump components may be damaged
• Continued use may cause further internal failure

In most cases, the product will need to be assessed and may require replacement depending on warranty status.
