  If the pressure from your Bosch Pressure Washer is pulsating, here's what you can do: * Run the pressure washer with the spray handle open and the nozzle at low pressure until you achieve a consistent working pressure. This will remove any air in the inlet water supply. * Ensure your water supply meets the specifications, with a minimum hose diameter of 1/2" or 13 mm. * Clean the water filter. * Straighten any kinks in the water supply hoses. * If you're using a high-pressure extension hose, remove it and retry. The maximum length for an extension hose is 7 meters.

  If your Bosch Pressure Washer motor stops, several issues could be the cause. First, check the fuse and replace it if it's faulty. Next, ensure the mains voltage corresponds to the specifications on the model tag. Lastly, the motor protector might have been activated. If so, allow the pressure washer to cool down for 15 minutes before restarting.

  Pulsating pressure in your Bosch Pressure Washer can be caused by several factors. It could be due to 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 the pressure stabilizes. Also, check that the water supply meets the specifications, with a minimum hose diameter of 1/2" or 13 mm. Clean the water filter if it's blocked, straighten any kinks in the water supply hoses, and if using a high-pressure extension hose, remove it and retry, ensuring it doesn't exceed 7 m.

  If the pressure on your Bosch Pressure Washer is too low but steady, the nozzle may be worn. Try changing the nozzle. Another possibility is a worn start/stop valve. Try activating the trigger five times in quick succession.

Why is no detergent taken in by my Bosch AQT 35-12+ Pressure Washer?
- J
  Jeffrey KruegerSep 6, 2025
  If your Bosch Pressure Washer isn't taking in detergent, make sure the adjustable nozzle isn't on a high-pressure setting. Attach the High-Pressure Foam nozzle or select the foam setting on the 3-in-1 nozzle. If the detergent is too dense, dilute it with water. If you're using a high-pressure hose extension, fit the original hose.
