| Cause | Solution |
|---|---|
| Not enough inlet water supply. | Turn water on fully. Check garden hose for kinks, leaks or blockage. |
| Pump is sucking air. | Check that hoses and fittings are airtight. Turn "OFF" machine, and purge pump by squeezing trigger gun until a steady flow of water emerges through the nozzle. |
| Water inlet filter is clogged. | Remove filter and rinse in warm water. |
| Discharge nozzle is obstructed. | Blow out or remove debris with the needle clean out tool. |
| Calcified gun, hose or power nozzle. | Run distilled white vinegar through the detergent tank, or soak the calcified part with the vinegar. |
