  If your Bosch Pressure Washer's motor refuses to start, there are several potential causes and solutions: * Ensure the plug is properly connected. * Try a different mains socket in case the current one is faulty. * Replace the fuse if it's faulty or blown. * Try using the pressure washer without an extension cable in case the cable is damaged. * Allow the motor to cool for 15 minutes if the motor protector has activated. * If frozen, wait for the pump, water supply hose, or accessory to thaw.

Why is the pressure pulsating in my Bosch AQT 33-10?
- P
  Paul MasseyAug 19, 2025
  Pulsating pressure in your Bosch Pressure Washer can be due to several reasons: * There may be air in the inlet water supply hose or pump. To resolve this, run the pressure washer with the spray handle open and the nozzle at low pressure until a regular working pressure is achieved. * The water supply may be inadequate. Ensure the water supply meets the specifications, with a minimum hose diameter of 1/2" or 13 mm. * The water filter could be blocked. Clean the water filter. * The water supply hoses might be squeezed. Straighten out any kinked hoses. * The high-pressure hose might be too long. Remove any extension hoses (max. 7 m) and retry.
