Why does my ARXP BOX5 160DTS Pressure Washer pump not reach working pressure?
- GGeorge GrantAug 11, 2025
If your ARXP Pressure Washer's pump isn't reaching working pressure, several factors could be at play. The nozzle might be worn and require replacement. The water filter could be dirty, so you should clean it. Ensure that the water supply is fully turned on. Check the tightness of hose fittings to prevent air from being sucked into the system. If there is 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. Also, if you're drawing water from an open container, make sure the suction height is not more than 0.5 meters; reduce it if necessary.
