Pressure Washer Maintenance: Tips to Keep Your Power Cleaner Running Its Best

Pressure washers are a great way to take care of jobs that would otherwise be too big or dirty for you to tackle. So whether you pressure wash your deck, clean the garage floor, power-clean your driveway, or pressure wash your car. 

Pressure washer maintenance is essential to get the most out of this handy tool.
This blog post will discuss some tips on keeping pressure washers running their best and avoiding making common mistakes while using them.

Before Using a Pressure Washer

Before you begin your cleaning task, look for anything that might cause an issue with the equipment.

Step 1: Check the fuel level

Check the engine’s oil and fuel levels first, particularly if the machine has been sitting for an extended period. Then, replace the oil or petrol if necessary, as directed by the manufacturer.

Check the air pressure of your inflatable tires: Make sure it’s at the correct level or within 15 and 25 PSI of the displayed reading.

Step 2: Check the debris screens

Check the water inlet screen, where you connect the garden hose. Clean any blockage with water if there are any. If it is damaged, replace it.

Step 3: Inspection of Hoses and Couplings

Inspect the pressure washer’s hoses. Look for any cracks or leaks, and replace them if necessary. Also, check that the hose connections are tight.

Step 4: Inspect the detergent system.

If the detergent siphoning tube is clogged, clean it out. Check the detergent system’s filter as well, if there is one.

Steps 5: Prepare the Garden Hose

If you have a long garden hose, coil it up and place it near the pressure washer. It will help keep your workspace tidy and organized.

Step 6: Turn the Pressure Washer On

Ensure that your pressure washer is turned on and off using the safety valve located at its main body. It is also a good idea to have someone nearby in case of an emergency.

Once you have completed your cleaning task, take a few minutes to clean up the pressure washer. It will help keep it in good condition and make it easier to store.

Cleaning a Pressure Washer

After you have finished using the pressure washer, clean all the soap suds off with water.

Cleaning the Pressure Washer’s Engine

Allow the pressure washer to cool down after turning it off. Then, take off the detergent siphoning hose and clean the screen with water to remove any residue leftover from your cleaning task.

Cleaning the Nozzles

Check the nozzles and remove any debris. Then, use a brush or needle to clear them of any blockages.

Cleaning the Gun

Remove the gun and spray it down with water. Then, wipe it dry with a cloth.

Cleaning the Pump

Disconnect the water hose from your pressure washer. Take off any debris screens and clean them with a brush. Then, pour a small amount of engine oil into the pump’s front and back chambers.

These are located at its base or side where the hoses are connected. Reconnect the water hose and turn on the pressure washer for a few minutes to allow the oil to circulate.

Turn off the pressure washer and wipe away any excess oil.

Steps to Cleaning Your Pressure Washer’s Exterior

  • Take off all the parts that you can, such as the gun and sprayer, then clean them with a brush or cloth dipped in water.
  • Wipe down the exterior of the pressure washer with a damp cloth or brush. Never use abrasives to clean your machine to damage the surface finish.

Protecting and Storing Your Pressure Washer

  • After you have finished cleaning your pressure washer, make sure to protect it from the elements.
  • If you are not going to use your pressure washer for an extended period, store it in a dry place.
  • Cover the equipment with a tarp or blanket.
  • Do not store the machine with its fuel tank empty, as this can cause problems in future use. Check your owner’s manual for the proper fuel levels.
  • Replace any damaged or missing parts before storing your pressure washer.

Why Perform Routine Maintenance?

  1. To avoid breakdowns,
  2. To avoid spending a lot of money on repairs,
  3. To keep you secure,
  4. To ensure that it functions correctly,
  5. To assure that it can endure hundreds of hours of usage.

Pressure Washer Maintenance Schedule

The Maintenance Schedule is split into timeframes ranging from:

  • Before each usage
  • After 200 hours of use, or
  • Every two years.

Engine Maintenance for Gas-Powered Pressure Washers

Pressure washer maintenance is key to keeping your power cleaner running its best. Maintenance needs vary between pressure washers, but gasoline-powered models generally require more than electric models.

  • If you are using a gasoline-powered pressure washer, check the engine oil level about once every three to five hours of use.
  • Check the air filter and replace it if it is dirty.
  • Replace the spark plug every 100 hours of use or annually, whichever comes first.
  • Keep a container of clean water nearby to extinguish any sparks that may occur.
  • Never smoke while working on or near the pressure washer.

Pressure Washer Maintenance Tips

  • The most important part of pressure washer maintenance is to read your owner’s manual. It will outline the specific needs of your machine and provide safety procedures.
  • When cleaning the engine, use a degreaser to break down any grease or oil deposits.
  • Be sure to wear safety goggles and gloves when working on your pressure washer.
  • Store any flammable liquids, such as gasoline, in a safe place away from the machine.
  • Avoid cleaning the engine while it is running.
  • Never attempt to repair your pressure washer if you are unfamiliar with its parts or how it works. Take it to a professional if you have any questions or concerns.
  • For electric models, unplug the machine before cleaning.

Wrap Up

Pressure washer maintenance is key to keeping your power cleaner running its best. Maintenance needs vary between pressure washers, but gasoline-powered models generally require more than electric models.
