Official Pressure washer parts

A power washer is a handy tool to have if you need to deep-clean an outdoor surface. They are effective at cleaning just about anything, including graffiti and dirt. With proper care, your power washer can last for years, but surprise issues do occur. You may find that the pressure isn't as high as it used to be. Your machine could also be shaking heavily or leaking water when it's running.

DIY tips to repair your power washer

  1. Check the water supply: Never let the water supply run too low. If water supply flow isn’t high enough, it will create a shaking feeling and affect your pressure levels. Fixing this may be as simple as opening the water supply faucet to provide the power washer more water.
  2. Check for leaks: Low pressure is often the cause of a leak in the supply hose or its connection. This is the first thing you should check when experiencing pressure issues.
  3. Check the air filter: If your motor is sputtering or not running correctly, it could be the result of bad air coming in via the intake. Routinely check your air filter, making sure it’s clean at all times.
  4. Change the nozzle: Sometimes, the water pressure coming from the power washer is too high. If this the case, switch out your current nozzle for a different one.

After you've pursued all of these troubleshooting methods, you may find that your pressure washer still doesn't seem to be working correctly. This could mean a faulty part is to blame.

Four power washer parts you may need for repairs

  1. Chemical injection valve: The chemical injection valve is responsible for mixing the cleaning detergent with the water before it is ejected from the hose. A wrench set is needed to install the new valve. Disconnect the spark plug before the replacement.
  2. Recoil starter: The pull rope is retracted by a spring in the recoil starter, so if the spring goes out, the rope won’t recoil when you release its handle.
  3. Unloader valve: The unloader valve recirculates water within the machine when the spray isn't on. If it is stuck closed, hot water will leak out on the ground through the pressure relief valve when the washer isn't spraying, meaning the unloader valve needs to be replaced.
  4. Hose: If you can no longer properly tighten the water hose, it may cause a leak or cause low-pressure spray.
