This article will be reviewing some of the common problems associated with a pressure washer and the solutions to them.

Common Problems Associated With the pressure washer and solutions

Troubleshooting your gadget or device before it develops a fault or while a fault is still minor will go a long way to save cost and prevent complete damage. These faults are usually common to a pressure washer. They include,

1. Engine issues

One common problem with gas or diesel engines is contaminated fuel which is often from dirty fuel or fuel containing water. For an engine to operate properly and without hassle, it requires clean and fresh. Always use clean containers or vessels when putting fuel in the engine of your pressure washer.

A dirty air filter could also cause issues for the engine of the pressure washer. If the air filter is dirty, air cannot get to the carburetor. As a result, the engine does not operate as efficiently as it should. It is advisable to check the air filter periodically and clean any dirt found around it.

2. Nozzle pressure

Low nozzle pressure causes the pressure washer to not function properly. Oftentimes, low nozzle pressure in the pressure washer results from a clogged nozzle or a poorly fitted nozzle. To prevent this, always check if the nozzle is properly fit or clogged before using your pressure washer.

3. Surge problems

If you notice a low water surge, it is best to check your water supply. If the source of water supply isn’t providing enough water needed by the pump, there will be a low surge of water. Therefore, before using your pressure washer, always check the water supply.

4. Excessive pressure

Too much of everything they say is bad. In as much as low nozzle pressure could cause an issue for your pressure washer, excess nozzle pressure could also be an issue. This is often caused when a small-sized nozzle is used. Using the proper nozzle size will easily fix these problems.

5. Pressure washer unloader issues

Sometimes, leakages and low pressure are caused by pressure washer unloader issues. To fix this, change the pressure washer unloader preferably to one that can accommodate more gallons per minute.

6. Leakages

Water leakages are not always a bad thing. It is mostly caused by a thermal relief valve that was installed to prevent the pump from overheating. The water in the pressure washer gets caught in the pump and freshwater cannot come in. To remove the trapped water, pull the trigger periodically (1 – 2 mins).


When your pressure washer has similar issues to the Ines listed above, quickly check and troubleshoot before taking it to a repairer.
