We are sorry to hear you are having difficulties with your pressure washer. Here are some troubleshooting steps that may help: 1. Clean Obstructed Nozzles: Soak all nozzles in a 50/50 mixture of warm water and white vinegar for about an hour. Then, use a nozzle cleaning tool or paper clip to remove any debris from the nozzle holes. Rinse with warm water your nozzles should now be clear and ready to use. 2. Remove Air from the Line / Bleed the Unit: Set up the unit as usual and avoid using an extension cord. Remove any nozzle from the wand. Ensure the GFCI on the power cord shows a green light. Turn on your garden hose but keep the pressure washer OFF. Squeeze the trigger for about 3 minutes to purge any air from the pump. Afterward, turn the unit on and reinstall a clean nozzle to continue using it. 3. Check Water Supply: Make sure the water source is fully opened and provides at least 45 PSI. There should be at least 10' of unrestricted hose between the faucet and the unit kinks or restrictions can reduce performance. This product includes a three-year warranty from the date of purchase.
