PULSING
Ryobi · Ryobi RY142300 2300 PSI Brushless Electric Pressure Washer
The water pressure cycles between high and low (pulsing or surging) during operation. This is one of the most common pressure washer issues. Causes: Air in the pump or water supply line — squeeze and hold the spray gun trigger with the high-pressure hose disconnected from the spray gun to purge air. The nozzle is partially clogged — remove and clean the nozzle tip, or try a different nozzle. The unloader valve is sticking — the unloader valve recirculates water back to the inlet when the trigger is released. If it sticks partially open during use, pressure will pulse. Tap the unloader valve housing gently to free it. If pulsing occurs only when the trigger is partially squeezed, this is normal — the unloader valve is cycling. Always squeeze the trigger fully or release it fully. The inlet water supply may have insufficient flow — ensure the garden hose delivers at least 2 GPM. A kinked supply hose restricts flow and causes pulsing.
