Troubleshooting your pressure washer

Hotsy hot water pressure washer troubleshooting

If your mobile pressure washer is acting up, don’t rush off to the nearest pressure washer repair shop. You don’t have to be a professional to troubleshoot the issue. In many cases, there’s probably a simple solution. Here are some of the most common pressure washer problems and how to fix them.

The nozzle or spray gun doesn’t work

Your pressure washer’s nozzles and spray guns can fail due to a variety of reasons. However, you can try to get them working again by checking the following:

  • Ensure the nozzle and spray gun connections are tight
  • Check the nozzle, spray gun and inlet screens for clogs
  • Check the O-rings and replace them if they’re damaged or dirty
  • Unfurl the pressure washer hose reel and check the hose for twists, kinks and leaks
  • Ensure you’re using the correct wand size for your machine

The engine won’t start

If you have a gasoline-powered pressure washer that won’t start, there are a few things you can do. However, ensure the ignition is off before investigating the issue. You can try the following to get it back up and running:

  • Run water through the system to remove air from the hose
  • Clean or replace the air filter
  • Check the oil level and top it up or change it, if necessary
  • Replace the fuel if it’s more than 30 days old
  • Ensure the spark plugs are connected
  • Turn off the choke

You’re experiencing low or undulating water pressure

Low water pressure can make it difficult to clean things. Therefore, if the water stream from your pressure washer is weak, check the following:

  • Ensure the spray gun is the correct size and installed properly
  • Make sure the nozzle isn’t in the low PSI position
  • Check your spray gun, nozzle and hose for any leaks or clogs

Always check the unloader valve

The unloader valve on your pressure washer prevents pressure from building up inside the pump when you aren’t using it. If the engine keeps shutting off or you notice low water pressure, the unloader valve may be damaged. Additionally, using a pressure washer with a broken unloader valve is unsafe and could seriously damage your machine. Therefore, you must get the issue fixed as soon as possible.

How to prevent problems with your pressure washer

Investing in regular pressure washer maintenance will keep your unit running smoothly and prevent small problems from becoming expensive repairs. Moreover, make sure you purchase pressure washer parts and accessories from a reputable and authorized dealer.
