What should I do if the car washer is not producing any pressure?

It is a common problem for a high pressure washer to have no pressure or unstable pressure during use, which will not only affect the cleaning effect, but may also cause damage to the equipment. Here are some common causes and solutions to help you quickly restore the normal operation of the high pressure washer.

 Common causes and solutions

1. Air is sucked into the high-pressure water pump or water inlet pipe

• Cause: Air enters the high-pressure water pump or water inlet pipe, which will cause unstable or intermittent pressure.

• Solution: Pull the trigger of the high-pressure water gun, lower the working pressure of the high-pressure cleaner and run it for a while until a stable pressure is generated.

2. Insufficient water supply

• Cause: Insufficient water source pressure or blockage of the water inlet pipe leads to insufficient water supply and failure to reach the pressure required by the equipment.

• Solution: Check whether the water source pressure is sufficient. If the water source pressure is insufficient, you can add a booster pump to increase the water pressure.

3. The water inlet filter is clogged

• Cause: The water inlet filter is clogged, resulting in poor water flow and reduced pressure.

• Solution: Clean the water inlet filter, remove the blockage, and ensure smooth water flow.

4. The high-pressure nozzle is worn or clogged

• Cause: The high-pressure nozzle is worn or clogged, resulting in scattered water flow and reduced pressure.

• Solution: Check whether the high-pressure nozzle is clogged or severely worn. If necessary, replace it with a new one.

5. Failure of the pressure regulating valve or relief valve

• Cause: The O-ring, spring and seat of the pressure regulating valve or relief valve are worn, or the valve is stuck, resulting in the inability to adjust the pressure normally.

• Solution: Check whether the O-ring, spring and seat of the pressure regulating valve and relief valve are worn or damaged. If necessary, replace the corresponding parts.

6. Damage to the internal sealing components of the high-pressure pump

• Cause: The sealing components (such as O-rings and water seals) inside the high-pressure pump are worn or damaged, resulting in water leakage and pressure drop.

• Solution: Check the sealing components inside the high-pressure pump and replace them in time if they are damaged.

7. The high-pressure pipe or filter device is kinked, bent or damaged

• Cause: The high-pressure pipe or filter device is kinked, bent or damaged, resulting in poor water flow and reduced pressure.

• Solution: Check the high-pressure pipe and filter device, and repair or replace the damaged parts.
