Pressure washers are used primarily for industrial cleaning, and it’s important to know how to change pressure washer parts. These machines are perfect for removing substances such as dirt, dust, molds and chemical substances from any kind of surface. Chemical detergents can be added to the pressure washer’s water supply for intensive cleaning. Some pressure washers are also able to heat water, ideal for removing oil. Pressure washers can be powered by either electric or gas. Gas-powered pressure washers are able to deliver twice the maximum pressure of electric-powered pressure washers.

Gas-powered pressure washers also possess advantages with regards to mobility. Electric-powered pressure washers can only operate when plugged into an electric outlet. However, despite their advantages over electric, gas-powered pressure washers pose an environmental hazard because it releases gasoline fumes, especially in enclosed spaces. Pressure washers, like other types of machinery, are prone to breakdown, and need to be maintained regularly for optimum performance. In the event that a pressure washer malfunctions, one should know how to change pressure washer parts.

Step 1: Inspect the Crankcase and Pumping Section

This section includes the whole engine, and minor parts used for pressurizing water such as pistons, o-rings, plungers, pumps and filters. If the pressure washer displays problematic symptoms such as oil leakage, no water being produced or noisy operation, it’s important to check each part of the crankcase and pumping section for effective troubleshooting. An oil leak, for example, may be caused by old pistons, o-rings, or plungers. Such defective parts immediately be disposed of and replaced by brand-new parts.

Step 2: Make Sure the Trigger, Hose, and Nozzle are Secure

The trigger is responsible for injecting the highly pressurized water out of the storage area and unto the hose. The trigger is made up of valves which support an inlet suction device. The suction device draws water from the storage area and pushes it up to the hose. The water traverses the length of the hose, and then shoots out of the nozzle at high velocity. If the pressure washer does not produce water, there may be a problem with how the trigger is connected to the pump and storage area, or how the trigger is connected to the hose. Check for leaks in the hose and the nozzle as well. Re-assembling the trigger, hose, and nozzle system is recommended for troubleshooting inadequate or nonexistent water output. It is also important to check if the trigger’s valves are not stuck or clogged by dirt.

Step 3: Check if the Drive Belt and Bearings Need to be Replaced

These two parts located directly adjacent to the main engine break down easily if the pressure washer is poorly maintained. By opening the engine’s casing, one can extract the drive belt and bearings for check-up and replacement. Check for any foreign material buildup on the drive belt and bearings, and make sure they are properly oiled before re-attaching them to the engine.

Once the problematic parts have been identified and replaced, make sure the pressure washer parts are properly located and screwed tightly into place. Don’t forget to replace the outer coverings as well. Test the fixed pressure washer to ensure that all parts are properly installed and working optimally.
