How to Repair a Pressure Washer

Designed to emit a high-pressure stream of water and cleaner to remove dirt and debris from the exterior of buildings and walkways, pressure washers make quick work of grimy surfaces when kept in peak operating condition. Over time, improper storage or lack of seasonal maintenance can cause issues that owners need to repair in order to return the electric or petrol-powered tool to operable condition and allow it to perform its dirt removing duties as intended. A bit of research into the proper repair methods and helpful tools allows owners to complete the work successfully in the span of a few hours, whether they buy the tools and replacement components at a local home improvement centre or online at eBay.

Diagnosing Pressure Washer Problems

With frequent use, pressure washer operators may notice small problems that magnify in a hurry without proper care. Two of the main problems that cause these machines to function incorrectly are blocked inlet filters with lack of soap spray and leaking oil or accumulating pools of oil.

To make repairs that last, owners should gather a few simple materials together, including hand tools and replacement parts. They should also find a suitable surface on which to work.

Repairing a Pressure Washer

Before commencing repairs, spread a large sheet of plastic material or a tarp over a hard, flat work surface to prevent water from pooling everywhere and reduce scratches or oil spills.

Cleaning a Clogged Inlet Screen Filter

Located inside the coupler that pipes the water into the reserve tank, through the pump, and out to the hose, the inlet screen filter protects the pump from contaminants in the water. When water spray pressure decreases, cleaning this clog takes only minutes. To begin, remove the coupler from the pressure washer by unscrewing it with a few twists and visually examine the mesh screen for large debris such as dirt, soap film, or paper. If present, remove the debris with a toothpick or scrub the screen with a toothbrush under a flow of hot water from the tap, and then wipe it with a clean cloth or a few sheets of paper towelling before reattaching it.

Remedying Overflowing Oil

During the course of operation, the level of oil and air mix in the motor area of the pressure washer rises and falls during the spray cycles to keep everything lubricated and running smoothly. From time to time, operators may notice a pool of oil underneath the washer or a slight leak. The main cause is usually too much oil in the reservoir. To take care of this problem quickly, insert the nozzle end of the vacuum suction pump and follow the manufacturer's directions to operate it.

Drain as much oil as possible, set the pump aside for later cleanup, and check the level of oil remaining in the washer using the pressure washer dipstick. The ideal oil level hovers at half a tank, so add or remove non-detergent 30-weight oil to achieve the proper level. This allows the machine to operate at peak reservoir capacity and prevents overflowing and splashing while the unit operates in work mode.
