Lelit Bianca: Adjusting the Pump Pressure

Below you will find instructions on how to increase or decrease the pump pressure on the Lelit Bianca Espresso Machine. (Difficulty ☕☕)

Tools Needed:

  • Flathead screwdriver
  • Backflush Blank
  • Portafilter

1. Remove the water tank and the drip tray from the machine as you will be tilting it to the left side (You do not need to remove the panels).


2. Next, tip the machine over onto its left side to access the adjustment knob on the rotary pump.


3. Using a flat head screwdriver, turn clockwise to increase the pressure and counterclockwise to decrease pressure. Place the machine back onto its feet and test using a backflush blank.

4. We are looking to land between 9 and 11 bars of pressure on the pump pressure gauge.
