Why is the water jet weak on my Makita HW1200?
- L
  Lynn RasmussenJul 27, 2025
  A weak or non-existent water jet on your Makita Pressure Washer can be caused by several factors: * No water supply: Make sure the faucet is fully open. If you're using a suction hose, ensure it's properly primed with water. * Poor water supply: Open the faucet completely. * Poor water hose connection: Check the connections between the water hose, the faucet, and the pressure washer's inlet. * Clogged hose, filter, or nozzle: Clear any blockages in these components. * Air blocking the water flow: Turn the switch off, then back on while squeezing the trigger. * Damaged or worn nozzle: Replace the nozzle. * Pump or valve malfunction: Contact an authorized service center for repairs.
