What to do if Blue Clean 1120 pump does not reach working pressure?

If your Blue Clean Pressure Washer pump isn't reaching working pressure, several factors could be the cause. First, the nozzle might be worn and need replacement. Second, the water filter could be fouled, requiring cleaning. Third, the water supply might be insufficient, so ensure the supply tap is fully open. Fourth, air might be getting sucked into the system; check the tightness of hose fittings. Fifth, there might be air in the pump; switch off the appliance and repeatedly depress and release the gun trigger until the water flows steadily, then switch the appliance back on. Sixth, the adjustable nozzle may not be correctly positioned; set it to the (+) setting. Finally, if water is being drawn from an open container at a height exceeding 0.5 m, reduce the suction height.
