This is typically an overheating or electrical supply issue.
- Tripped circuit breaker: The unit draws 13 Amps. Allow it to cool, then restart. Do not run it on the same circuit as other high-draw appliances.
- Supply voltage below minimum: Verify that only the pressure washer is running on this circuit. A voltage drop under load will cause shutdown.
- Inadequate water supply: Not enough inlet water causes the pump to overheat. Turn water on fully. Check garden hose for kinks, leaks, or blockage.
- Pump sucking air: This leads to overheating. Ensure all hose connections are tight and the water source is fully open.
If the problem continues, the thermal overload protector is cycling. Check water supply and electrical circuit load. Let the unit cool completely between cycles. Never leave the product running unattended.
