What to do if my Kärcher Pressure Washer unit does not come up to pressure?

If your Kärcher Pressure Washer isn't building pressure, several factors could be at play. First, ensure the water hose is properly connected, as the pump might be sucking in air. Also, check and clean the strainer at the pump inlet, as it might be blocked. You may also need to switch off the unit, retract the handgun lever, and switch on the unit with opened handgun, repeating the procedure if necessary. Additionally, make sure the water tap is open. Check and seal any leaks. Dismantle and clean the strainer. Finally, fill up the cleaning agent container or set the cleaning agent valve to '0'.
