All of a sudden the POWERWASHER lost pressure. Engine runs fine. Only a few years old and used sparingly by home owner I ran it with hose attached and removed gun ad hide. Nothing came out

Possible causes for a Simpson PS325 power washer losing pressure while the engine runs fine include:

1. Clogged or worn nozzle.
2. Air in the pump.
3. Inlet water supply is insufficient or blocked.
4. Worn pump seals or valves.
5. Unloader valve malfunction.
6. Dirty water filter.
7. Hose or wand leaks.

Check each of these components to identify and fix the issue.
