Pressure Washer Maintenance Tips to Keep Your Machine Running

If you’re in the pressure washing business, your equipment is the backbone of your company. Average machines can cost anywhere from $250-$6,000, so that’s reason enough to want to protect your investment! To ensure your equipment keeps running as it should, here are some pressure washer maintenance tips to keep your equipment tip-top!

How can I keep my pressure washing equipment running longer?

Like a car needs regular maintenance, so does your pressure washing equipment. Filters need cleaning, oil needs changing, and worn seals need replacing. We’ll review the basic upkeep to extend the life of your equipment.

Begin With a Basic Inspection

Start by looking at your oil ﬁlter, spark plugs, and air ﬁlter. Replace any if they look dirty or worn. You probably won’t need to replace your air ﬁlter that often since the equipment is used in a clean environment.

Check your oil next. If it’s dirty, drain through the drain hose at the end and replace it. Then check your fuel ﬁlter for particles and replace it if needed.

You should have an hourly maintenance schedule afﬁxed to each power washing machine with suggested tasks. Follow all of them except the oil changes.

We recommend changing your oil more frequently. Most of these engines run full throttle, and oil needs replacing around every 40 hours of use or once every two weeks.

Pump Maintenance and Inspection

Inspect your pump for leaks or drips that indicate a seal needs replacing. The only other thing to check on your pump is the oil. You won’t need to change it often. It requires changing after the ﬁrst 50 hours and then every 500 hours. Since no combustion occurs in the pump engine, the oil doesn’t break down. You’ll probably only need to change it 1-2 times yearly.

Check for Leaks

When looking for leaks, pay close attention to the intake side. A leak there will lower the pressure and cause your pump to cavitate (intense vibrating). Take care of it immediately before it damages the inside of your pump.

If you’re drawing from a tank and not a pressure hose, pressurize using the pressure hose from the tank, and leaks will show. Sometimes it’s just a loose ﬁtting or a worn-out o-ring.

Clean Your Water Filter

If your water ﬁlter is dirty, replace it, but don’t stop there. You must clean your tank to prevent sediment from clogging your ﬁlter again. Sediment from construction meters and water quality all affect how fast your ﬁlter clogs.

Check Your Battery

Keep your battery terminals clean. Corrosion is common and easy to clean with battery protection spray. If your battery has lost charge during storage, it may have drained and need a new charge.

Examine the Burner

Replace the oil ﬁlter in the burner and change the fuel nozzle, and remember to clean and adjust the electrodes. They may need a descaling if you work with hard water. That’s about all you need to do with the burner.

Inspect Your Nozzles

Water is powerful and can lead to nozzles wearing out. You won’t know you have a problem unless you check your pressure. A quick coupler gauge easily measures your PSI. Remember that the closer the pump is connected, the more accurate your reading will be. If you attach it after the burner, you’ll lose about 100-300 PSI, so account for that. A pump valve cap allows you to connect the gauge straight to the Head of the pump for accuracy.

Visually inspect all your nozzles. Residential use should get anywhere from half to an entire season of use. Check your pressure nozzle, fan tip, and extended-range nozzles. Quick couplers all have o-rings. Standard sizes are ¼”, ⅜,” and ½.” Replace each one, ensuring they are seated correctly, including the downstream injectors.
