Pressure Washer Repair Near You

Gas pressure washer pump and engine repair.

Gas pressure washers combine a small engine with a high-pressure piston pump, and either component can fail independently. Most pressure washer repairs involve one of two systems: the engine (carburetor, ignition, oil) or the pump (seals, pistons, unloader valve, spray gun). Identifying which system is the source of the problem is the first step in any pressure washer diagnosis.

Engine-side repairs on pressure washers follow the same patterns as any small engine: carburetor cleaning for units that won't start or run rough ($50–$90), oil changes and air filter replacement for maintenance ($20–$40), and ignition repair for no-start situations. Most residential pressure washers use Honda GC or GCV engines, Briggs & Stratton 875 or 950 series engines, or Kohler series engines — all widely serviced.

Pump-side repairs are different. The most common pump failures are worn piston seals (causing pressure loss), a failed unloader valve (causing pressure fluctuation or the pump to lock up), and a cracked pump head from freezing. Seal kits for Annovi Reverberi (AR), General Pump, and Cat Pump — the most common OEM pump brands — are widely available. A pump seal job typically runs $60–$120. A frozen and cracked pump may require full pump replacement ($100–$250 for the pump).

To extend pump life: never run the pump without water flowing through it (even for 30 seconds), flush the system before winter storage, and use pump protector/antifreeze before cold-weather storage. Frozen pump damage is the most preventable pressure washer repair and one of the most expensive.
