Top Maintenance Tips For Your Pressure Washer's Power and Pump Components

Looking to keep your pressure washer in good working order? Here are some tips for keeping the power and pump components in top condition:

Dirt, grease, and grime can build up on the metal housing covering the washer's engine and pump components. This buildup over time reduces the power of your pressure washer to create high-pressure water under hot conditions. It also puts strain on the pump's bearings, seals, and o-rings which must perform well under extreme heat and pressure.

There are various pressure washer accessories that can be used to help improve the performance of your pressure washer. Some of the most common supplements include nozzles, wands, and spray guns.

Make sure you have a product such as Tufoil in your storage tank to ensure that all moving parts are correctly lubricated at all times. This will prevent rusting or corrosion, which can reduce performance or damage components if left unchecked.

1. Clean the pump regularly.

Remove any debris or buildup from the pump housing with a brush or garden hose. This will help keep the pump running smoothly.

Cleaning the pump regularly is an essential part of maintaining your pressure washer. Make sure to remove any buildup or debris from the pump housing with a brush or garden hose.

2. Wash out the detergent tanks regularly.

Regularly cleaning the detergent tanks will keep them from rusting and prevent the detergent from breaking down.

Washing out the detergent tanks with soap and water regularly will help prevent corrosion and ensure that your soap is still working at its best throughout your pressure washer's life.

3. Keep an eye on the hose and replace it as necessary.

Leaks can be costly to repair, so keeping an eye on hose condition is essential for saving money over time. Replacing worn hoses frequently may be more expensive upfront but cheaper than waiting until there are significant leaks or problems with your pump parts caused by deteriorated hoses.

4. Don't forget about the nozzle.

The nozzle that comes on the end of your hose is an integral part of your pressure washer and should be replaced if it becomes worn or damaged. Replacing a worn nozzle will ensure your pressure washer's performance is optimal.

Don't forget about the nozzles, which are an essential part of your washing power and potential to cause damage if misused. Keep them clean and replace them if they become worn or damaged for best results with your pressure washing needs.

5. Check the inlet water filter for obstructions.

The same goes for the chemical injector screen or nozzle if equipped with one. The spray tips should also be inspected to verify that they are not worn down or plugged up.

Inspect all hoses and fittings to ensure they are properly connected and functional with each use. Ensure there are no leaks at any fittings or connections between components of your power washer's system. The pump's intake fitting should also be checked to ensure it has not vibrated loose from its original location.

Also, inspect all hose couplings for evidence of damage, leaks, or other signs of wear and tear that can compromise their look for signs of wear, fraying, or charring, and replace if necessary. A damaged power cord can pose a safety hazard.

6. Lubricate the seals on the pump every few months.

Keeping the pump seals lubricated will help extend their life and keep them functioning optimally. Inspecting and replacing rubber O-rings should be done at least once a year or as needed to ensure your pressure washer's system is working correctly.

A little bit of oil can help keep the seals lubricated and prevent them from drying out and cracking.

7. Inspect the pressure hose regularly.

A damaged hose can lead to significant problems, so it is crucial to inspect the hose regularly for signs of wear or damage. Inspecting hoses regularly will help prevent leaks and other types of failure. Replacing badly worn hoses as needed will ensure your pressure washer remains in good overall condition.

8. Tighten all connections regularly

Make sure that all connections are tight at both ends before using them, including any nozzle quick-connections, water faucets, or garden hose couplings.

Tighten any loose connections at either end of your system before you use it again...even for something simple like washing your car with a pressure washer or spraying down some debris on your lawn!

Precautions/Safety Information:

Make sure to consult your owner's manual before performing any maintenance on your pressure washer, especially if you are unfamiliar with their parts or the system in general. The information here is intended as a guideline, not comprehensive instructions. When using a pressure washer, always wear appropriate safety equipment, including gloves, goggles, ear protection, etc.… If any power cords are frayed or damaged, get them replaced immediately; do not attempt an electrical repair yourself!


You should regularly maintain your pressure washer to ensure it continues working optimally and safely. Keeping up with the proper maintenance for your system will help extend its life and performance and prevent further costly repairs or malfunctions.
