Why is the pressure pulsating on my Bosch GHP 5-13 C Pressure Washer?
- A
  Angela ShannonAug 26, 2025
  If the pressure is pulsating in your Bosch Pressure Washer, consider these potential causes: * Air in the inlet water supply hose or pump: Run the pressure washer with the spray handle open and the nozzle at low pressure until the pressure stabilizes. * Inadequate water supply: Ensure the water supply meets the specifications, with a minimum hose diameter of 1/2" or 13 mm. * Blocked water filter: Clean the water filter. * Squeezed water supply hoses: Straighten any kinked hoses. * Overly long high-pressure hose: Remove any extension hoses and try again, keeping in mind that the maximum extension hose length is 7 meters.

Why is the pressure too low, but steady on my Bosch GHP 5-13 C Pressure Washer?
- C
  Catherine BrownAug 30, 2025
  If the pressure is too low but steady on your Bosch Pressure Washer, it could be due to a worn nozzle that needs to be changed. Another possibility is that certain accessories naturally deliver lower pressure; in this case, activate the trigger five times in quick succession.
