Why is the pump leaking water on my LAVAZZA LB 4712?
- S
  Stacy CarrilloSep 5, 2025
  If the pump on your LAVAZZA Coffee Maker is leaking water, it could be due to a poor mechanical seal of the shaft or the o-Ring. Check the pump and take any corrective actions. Loose inlet and outlet connections can also cause leaks; tighten the connectors. Additionally, check if the hexagonal nut of the pressure relief valve or the filter are loose, and tighten them. Finally, a defective gasket or o-Ring of the pressure relief valve of the filter can cause leaks; replace the gasket and the o-Ring, being careful not to change the calibration of the valve.

  If the pressure gauge on your LAVAZZA Coffee Maker indicates an unacceptable pressure, the pressure gauge itself might be defective and need replacement. Alternatively, the boiler calibration could be incorrect, requiring adjustment. Also, the power-pump calibration might be incorrect and need adjustment.
