5 Common Problems with Pressure Washers

March 25, 2021

Pressure washers are helpful tools to have for so many different outdoor projects. From cleaning your siding to deep cleaning, the deck, a pressure washer makes it easier than ever. Pressure washers are definitely an investment though; they don’t come cheap! When you invest in a good pressure washer and then it starts to have problems, it’s frustrating, to say the least. Let’s discuss the 5 most common problems with pressure washers that you should look out for.

  1.   Low Pressure

The whole point of a pressure washer is to have high-pressure water for the task at hand. If your pressure washer starts struggling to have the high pressure you’re used to, it’s most likely because there’s dirt in the pump. Find out what size nozzle your pressure washer takes and replace that piece. Most of the time, that quick and simple repair will get it back to the high pressure that you’re used to!

  1.   Leaking Water

If your pressure washer is leaking water, stop using it until you can fix the problem. There are multiple seals throughout the interior of the pressure washer and if any one of the seals starts to go bad, water will leak. It becomes a process of elimination to find out which seal is leaking and replace it.

  1.   Pulsating

If your pressure washer is pulsating, you need to clean your inlet and discharge valve. After 5 to 6 uses, the inlet and discharge valve will get clogged up from debris that comes off during the power washing process. Clean the inlet and discharge valve every 5 to 6 uses, and after each use that involves a wood surface, to avoid pulsating.

  1.   Running Harder Than Normal

If your pressure washer is running hard, it could be because the water you’re using is too hot. If you have a hot and cold valve outside, make sure to only use the cold. If you only have a cold valve and the problem is still happening, it could be because the sun heated up the water in the hose. Let the cold water run for a few minutes and then try again. If the issue persists, you likely have a deeper mechanical issue to blame.

  1.   Pump Overheating and Cavitation

A pump that’s overheating has probably spent too much time in the by-pass. Pump cavitation will happen if there isn’t enough water being supplied to the pressure washer per minute. Read the specifications of your pressure washer to determine how many gallons of water per minute it needs to run properly.
