Pressure Washer Repair | DIY or Professional?

Depending on how you use your pressure washer, sometimes it can break down, lose a part or wear out some of its components.

If this happens, it does not mean that you should fork out your hard-earned cash for another pressure washer.

 
 

Investing in a new pressure washer is an expensive venture. Fortunately, you can bring your cleaning equipment back to life.

Does your pressure washer have a problem?

 

 

It is important to know how to diagnose your equipment.

Otherwise, it will be difficult to conduct a repair or call on a professional to fix the item. It will be helpful to understand the factors which influence the performance of your power washer. Lack of adequate power can lead to pressure drops and eventually poor performance.

It is, therefore, important to check that the power washer is connected to the appropriate power supply.

 
 
 

The second factor affecting the performance of your cleaning equipment is inadequate water flow.

Every pressure washer is designed for an optimal water flow. Usually, it is expressed in gallons per minute (GPM). Therefore,  check if your pressure washer is running at the correct GPM. This can save you the cost of calling a professional for a repair that you could have completed.

 
 

Dirt accumulation will impact the operation of your pressure washer.

The intake valve, regulator, pump valves, the unloader, the outlet hose, and nozzle are areas that attract grime. If the valves are clogged, they are likely to affect the performance of a pressure washer. Blocked nozzles affect the water flow and discharge pressure. This is a simple repair, which may be effected through flushing the equipment with water.

 
 

The flow of air into the pressure washer could cause more harm than a dirt blockage. If there is a large volume of air in the pressure washer, it can reduce the pump discharge pressure. In some cases, it can lead to pump cavitation.  Expel the air from the system through a bleed valve.

 

Other obstructions, apart from dirt or air, along the path of water can be troublesome for your pressure washer. They can include, but are not limited to, sand, crooked hoses, debris in the intake filter, and foreign material in the nozzle. All these can hamper the performance of the pressure washer.

 

If your pressure washer has mismatched components or parts, its operation may be affected. It is important that the parts in the machine fit the specifications in the manual. The most sensitive parts include the nozzle, gun, unloader and regulator. If there is a mismatch of the components above, it will most likely cause a problem.

Leaks also influence the performance of a pressure washer. If there are leakages along the water path, they will affect the overall water discharge pressure. Check the guns and hoses for water leakage. Furthermore, if the unloader valve is not adjusted correctly, it can also influence the pressure washer.

 

Do not use hot water on a machine model that is not designed to accommodate the higher temperature.

Also, if the oil is not regularly changed, as required in the gas-powered models, it can lead to problems. Refer to your operating manual for the oil specifications and replacement frequency.

 

If the drive belt is loose or there are worn components, the pressure washer will not function properly.

Now that you know the performance killers of a pressure washer, do you choose the DIY option or seek the assistance of a professional?

How to care for your pressure washer

 

Considering the cost of some pressure washer models and that of contracting repair services, you need to maintain it to ensure longevity.

Let’s look at some of the things which can extend the lifespan of your pressure washer.

First, before every use, make sure the o-rings are in good condition.

Properly tighten all nozzles. You should also ensure that the nozzles are clean.

 

Where you are using a gas-powered pressure washer, be sure to refill it with fresh gas, and use a fuel stabilizer.

Check your inlet water flow, pressure and temperature. As mentioned earlier, the correct inlet water flow is necessary for optimal machine performance.

 
 
 
 
 

When you finish using the pressure washer, always unplug it from the power terminal.

Then, clean up the detergent dispenser compartment (if applicable).

Wash the inside of the pressure washer to remove any accumulated dirt.

Before you store your machine, make sure it is completely dry to prevent mold growth.

Lastly, keep it in a place where it cannot be affected by extreme weather elements.
