Honda pressure washer troubleshooting

In order to provide a long service life of Honda pressure washers, you must follow the rules of operation and repair them in a timely manner. Below we represent Honda troubleshooting table. It identifies the main faults of Honda pressure washers and reveals their nature. Thus, the performance loss associated with “no pressure” problem takes place rather often. Other problems of not working equipment happen as well. Our table will tell, how you should proceed in their cases.

Continued on next page.Air in hose.Turn off the engine, then the water source. Disconnect the water source from the pump inlet and turn the water source on to remove all the air from the hose. When a steady stream of water is present, turn the water source off. Re-connect water source to pump inlet and turn on water source. Squeeze trigger to remove remaining air.
No or low pressure (initial use).Choke in the “CHOKE" Position.Move choke to the “NO CHOKE” position.
High pressure hose is too long.Use high pressure hose under 100 feet (30m).
Will not draw chemicals.Spray wand not in low pressure.See How to Use Spray Wand section.
Chemical filter is clogged.Clean filter.
Chemical screen not in cleaning solution.Make sure end of chemical hose is fully submerged into cleaning solution.
Chemical is too thick.Dilute chemical. Chemical should be the same consistency as water.
Pressure hose is too long.Lengthen water supply hose instead of high pressure hose.
