What is the most common problem with pressure washers?

A clogged nozzle is often the main cause of low water pressure in pressure washers. Over time, dirt and debris build up in the nozzle and restrict the flow of pressurized water. A laundry service expert can clean the nozzle with a brush or introduce compressed air through the nozzle to solve this problem. One of the most common causes of power problems is clogged air filters.

The air filter is responsible for removing dirt and dust from the air before it enters the engine and, if clogged, can restrict airflow and cause the engine to lose power or not start at all. If the pressure washer doesn't start or doesn't keep working, there are 21 possible causes. Most of them are related to an incorrect configuration (for example, the fuel valve is not fully open), but it depends on whether it runs on gasoline or electricity. If the pressure washer doesn't generate all the pressure, there are 13 possible causes.

Most are related to poor water flow (for example, the nozzle has some dirt stuck inside), but it depends on whether there is no pressure or if it is pulsating (high and then low). A worn nozzle produces a lower pressure because there is less resistance to water flow. A pump generates flow, not pressure. The size of the nozzle hole determines the flow resistance and, therefore, the pressure created.

As the nozzle wears, the hole size increases, resulting in less resistance. Often, pressure-related problems are not due to the pump, but to the subsequent components. If you have low blood pressure, they can only be due to two things. The thing is that the pressure washer has the wrong nozzle size or its nozzle is worn out. To solve this problem, be sure to use the correct size nozzles.

A leaking pressure washer could be a sign that the seal is worn out. There are several seals all over the pressure washer. And a faulty seal is enough to create a leak. If there were no relief valve, pressure would build up inside the system (when not in use), so when the trigger was pulled, the engine would stall or a weak part, probably the O-ring of the pressure hose, would explode. Gas-charged shock absorbers use a chamber that responds to pressure fluctuations, absorbing pressure peaks.

The purpose of troubleshooting the pressure washer is to diagnose the problem and find a solution to fix it, so that the pressure washer can work properly. However, we have an article that offers more advanced pressure washing tips to unlock the most effective and efficient cleaning process possible. He has also worked as a commercial pressure washer in a processing plant for 3 years and has been using commercial and residential pressure washers for more than 15 years.
