Wagner Gas pressure washers

Official Wagner gas pressure washer parts

Wagner pressure washers provide you with the cleaning power you need for outdoor projects. Powerful engines on Wagner gas pressure washers drive pumps to deliver the pressurized spray you need to clean decks and driveways. When your Wagner gas pressure washer isn't working well, find the parts you need to fix the problem at Sears PartsDirect.

What to do when the engine won't start on your Wagner gas pressure washer

When the engine doesn't start, first make sure the rocker switch that controls the engine is in the On position. Next, check the fuel; the engine won't start if the engine is out of fuel or if the fuel is stale or contaminated with water. Replace the fuel in the gas tank if the fuel is older than 3 months.

Bad fuel can contaminate the carburetor. Clean or replace the carburetor if it's gummed up from using stale fuel.

The engine may also need a good tune-up so it will start easily. A tune-up includes changing the oil, changing the spark plug, replacing the air filter, checking the ignition system and adjusting the throttle and choke controls.

A bad recoil starter can prevent the engine from starting. If the engine doesn't spin when you pull the starter rope, you'll likely need to replace the recoil starter.

What causes a Wagner gas pressure washer to spray too hard

A failed unloader valve can cause high pressure at the nozzle. The unloader valve recirculates water to the pump inlet when the pump is running but the spray wand isn't in use. If the unloader valve sticks shut, outlet water pressure builds up until you trigger the spray wand or the pressure relief valve trips to release excess pressure. Replace the unloader valve if excessive pressure builds when the spray wand isn't in use.

Some pressure washers have a pressure regulator that limits the water pressure. A defective pressure regulator can cause high pressure at the nozzle. Replace the pressure regulator if it doesn't regulate outlet water pressure properly.
