Power Washer has no pressure, any ideas - Psi Blue Max 2200 High Pressure Gas Power Washer

1. If you have an inlet chemical injection valve make sure that the hose is intact and that the valve is closed.
2. Purge all air from the line by holding the nozzle actuation lever open until all air has been purged. When you connect the water supply hose turn it on before connecting the high pressure hose and let the unit self purge to the pump outlet high pressure hose fitting. Then connect the high pressure hose.
3. You could have a stuck spring and ball inside the high pressure head of the pump. You can tip the unit on its' side and add a substantial amount of WD-40 to the water supply hose fitting in an attempt to free the springs and balls.
4. Try BRIEFLY running the unit without the hose connected to see if there is high pressure water ejected from the high pressure fitting.
5. Inlet water screen at hose connection is clogged (hose screen and rubber) Check screen for debris.
6. The water strainer is clogged. (Almost looks like an LPG regulator just after but in line of the supply hose connection to the pump)
