Why Should I Perform A Routine Maintenance Check?

Here are some of the top reasons why performing routine maintenance on your gas power washer is important:

It helps prevent unnecessary breakdowns and other inconveniences
You’ll be able to avoid expensive repairs
Regular pressure washer upkeep ensures the performance of your equipment is consistently well
It will also guarantee that your machine will be able to withstand hundreds of hours of use


Generally, gas-powered washers require extra maintenance in comparison to their electric counterparts. It’s a must to winterize these powerful machines first before putting away during the cold winter months. Nonetheless, it’s not as daunting as you may think.

Also, some maintenance requires your machine to be running. Hence, it’s vital to refer to the manufacturer’s manual for any specific guidelines suitable for the model of your equipment.

Importance Of Understanding The Parts Of Your Gas Pressure Washer

Before going right ahead with maintenance, familiarize yourself with the various components of your outdoor cleaning equipment. Although pressure washers do not come with the same parts, they do include basic components, including hose, relief valve, gun assembly, unloader, and a pump.

A hot water gas power washer comes with additional parts that cold water models don’t. This includes a float tank and a heating coil. So refer to your unit’s manual to have a clear idea of its diagrams and descriptions.

Meanwhile, some may need extra care and upkeep than others. For example, some of the most affordable washers out there are virtually disposable. They have a design where you don’t need to change their oil or even perform other kinds of routine maintenance. Thereby, once these units stopped working for some reason, you have little to no hope of bringing them back to life.

So if you want something that’s more maintenance-friendly, opt for high-quality washers from a reliable brand.

Maintenance Guide Before Each Use

Thankfully, there’s no need for gas pressure washer maintenance to be difficult. As long as you keep up with a few basic practices, your unit will run strong with minimal extra effort on your part.

So follow these simple steps before using your power washer to ensure it’s always in good working condition:

Step 1: Check your unit’s fuel levels and engine oil. If both fuel and oil are running low, make sure to top them off. Furthermore, check to see if the oil needs changing and only use oil as per the manufacturer’s recommendation. Do not forget to consult your washer’s manual for instructions.

Step 2: Make sure to check and keep the air pressure of the tires correspond to the value indicated on the tires or at least within 15 and 25 PSI.

Step 3: Inspect the water inlet and in-line screens if they are clogged or dirty. If so, flush using clear water if necessary. Also, see if there are any damages beyond repair. If this is the case, replace the water inlet with a new screen and rubber washer. For the in-line, you need to get a new O-ring and screen.

Step 4: Examine your high-pressure hose and replace if there are cuts, bulging, abrasions, or leaks and if there’s a damage or movement on the couplings. When shopping for a new hose, get one with its pressure rating that exceeds the maximum rating of your unit.

Step 5: Clean your gas power washer’s filter and detergent injection tube if clogged or dirty. Moreover, check for any tear or leaks and ensure that its fit on the barbed fitting is tight and secure. You also need to replace the siphon or tube if damaged.

Step 6: Examine the wand extension, spray gun, and spray tip to ensure that all connections are tight.

Step 7: Test spray the wand assembly if everything is operating properly. You may need to replace the O-rings of your gas pressure washer if there’s a leak on the connectors. Likewise, you need to clean nozzle orifices if there’s clogging.

Step 8: Flush out your garden hose of dirt and debris before attaching it to the pump inlet.

Step 4: Remove your garden hose. Also, disconnect the spray gun, wand extension, and the high-pressure hose. Afterward, drain any water left from the tools.

Things To Remember Before Storing Your Pressure Washer

Unlike commercial pressure washers, the engine life span of the residential type is limited. Nevertheless, applying these power washer storage tips can help extend the life of your unit:

Even if the crankcase oil had only a few hour’s worths of uses, drain it and refill with clean oil. Make sure what oil type and viscosity are recommended by the manufacturer.
Let the engine run for a few minutes so that all internal parts get coated with fresh oil and anti-corrosion additives. Doing so will provide your pressure washer with the best possible protection while not in use. Plus, it will be ready anytime you need it for the next cleaning season.
Always operate your gas pressure washer with fresh fuel mixed with fuel stabilizer first, whether it’s dry or full of gas. Allow its engine to run for several minutes to ensure the treated fuel supplies the carburetor. Drain its tank and let it run dry.
Another thing you need to do before storing your washer for the winter is to flush out its pump. Leaving the pump filled with water in a place with a freezing climate will damage the pump.
