  If the electric motor of your Unitor Pressure Washer suddenly stops and the motor protection switch trips, it could be due to several reasons. First, check for poor water supply and eliminate the cause before restarting the machine using the ON/OFF switch. A burnt fuse can also cause this issue; replace it, but if it burns again or the motor is noisy, seek assistance from a qualified service. Finally, ensure that the power supply provides the correct voltage.

  There are several reasons why the electric motor of your Unitor Pressure Washer might not start. First, ensure the machine is properly connected to the power supply. Second, check the fuse and replace it if it's burnt; if it burns again, contact a qualified service. Third, make sure the water supply is sufficient, as a tripped low water cut-out can prevent the motor from starting. Fourth, verify that the EMERGENCY STOP switch is unlocked by slightly turning it clockwise. Finally, ensure the phase is correctly mounted according to the electric wiring diagram.

  If you're experiencing vibrations on the high-pressure hose and spray pistol of your Unitor Pressure Washer, it could be due to air in the unit or pump valves sticking/dirty. To resolve air in the unit, bleed it by opening the pressure regulating handle and pistol until continuous pressure is reached. If the pump valves are sticking or dirty, remove, clean, and reinstall them.
