Why is the pressure pulsating on my Bosch AQT 42-13 Pressure Washer and how to fix it?

If your Bosch Pressure Washer experiences pressure pulsation, it could be due to several reasons: * There might 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 regular working pressure is achieved. * The water supply may be inadequate. Ensure it meets the specifications, with a minimum hose diameter of 1/2" or 13 mm. * The water filter could be blocked, requiring cleaning. * Check for and straighten any kinks in the water supply hoses. * If using a high-pressure extension hose, remove it and retry, ensuring it doesn't exceed the maximum length of 7 m.
