Fluctuating Pressure
Pressure goes up and down. This is annoying. The engine might be starving. Check the fuel line. Is it free of dirt? The carburetor needs adjustment. This part mixes fuel and air. A dirty spark plug causes problems. Clean or replace it. The unloader valve may stick. This valve controls pressure. Lubricate it if needed. The pump could also falter. Internal parts might be failing.
No Pressure At All
Absolutely no power. This is a big problem. First, check the water supply. Is water even getting in? The pump might be dry. Prime the pump correctly. Add water to the pump.

Wand Not Spraying
The wand might not spray. This can be frustrating. First, check the water supply. Ensure the hose is connected well. Turn on the water fully. Next, examine the wand’s trigger. Is it stuck or jammed? Try to free it gently. Look for kinks in the hose. A pinched hose restricts water. Sometimes the wand itself clogs. Remove the nozzle. Flush the wand opening. This can dislodge blockages. Test it again.
Incorrect Spray Pattern
The spray pattern might be wrong. It could be too wide. Or too narrow. This affects cleaning efficiency. Nozzles create different patterns. They have different spray angles.
