Low Water Pressure
Is the pressure weak? The water source might be low. Use a stronger water supply. Check for kinks in the hose. A partially blocked hose hurts pressure. Clean the inlet filter again.

Engine Won’t Start
Is the engine dead? Check the fuel level. Add fresh gasoline. Make sure the fuel valve is open. Prime the engine if needed. Check the spark plug. It might be dirty or loose. Clean or replace the plug. Ensure the choke is set correctly. For electric models, check power. The outlet must work.
Engine Stalls Or Runs Rough

Leaks From The Unit

Air In The System
Air trapped inside is common. You need to purge it. Turn on the water supply. Squeeze the trigger on the spray gun. Let the water run freely. Hold the trigger for about 30 seconds. This flushes out trapped air. Repeat if needed. Air prevents proper pressure. It causes weak spray. Get the air out.

Clogged Nozzles

Worn O-rings And Seals
O-rings and seals wear out. They prevent leaks. Leaks mean lost pressure. Check all connections. Look for drips. Replace any damaged rings. Ensure they fit snugly. This restores the seal. Pressure should return.
Unloader Valve Adjustment

Internal Pump Damage
Internal pump damage is serious. The pump creates pressure. If it is damaged, no spray. You might hear strange noises. Look for leaks from the pump. This issue needs professional help. Repair or replacement is likely. Your washer may need a new pump.
