Why doesn't my Michelin Pressure Washer pump reach working pressure?
- M
  Mrs. Andrea PetersAug 5, 2025
  If your Michelin Pressure Washer's pump isn't reaching working pressure, several factors could be at play. Firstly, a worn nozzle can be the culprit, requiring a replacement. Secondly, a fouled water filter restricts water flow, so cleaning it is essential. Thirdly, ensure the water supply pressure isn't low by fully opening the water supply tap. Fourthly, air being sucked into the system can impede pressure; check the tightness of hose fittings. Finally, air trapped in the pump can cause issues; to resolve this, switch off the appliance, repeatedly depress and release the gun trigger until a steady water flow emerges, then switch the appliance back on.

Why does the pressure drop during use with my Michelin Pressure Washer?

  Nicole MorrisAug 15, 2025
  If the pressure drops during use with your Michelin Pressure Washer, it could be due to several reasons. If you're using an external tank for water intake, try connecting the appliance to the mains water supply. Also, if the intake water is too hot, reduce the temperature. Check if the nozzle or filter is clogged and clean them if necessary.
