Lelit Bianca: Replacing Water Reservoir Tubing and Sensor Wire

In this article, you'll see the step-by-step process for replacing the reservoir tubing and sensor wire for the Lelit Bianca espresso machine. (Difficulty ☕)

Tools needed:

  • Flathead screwdriver
  • #2 Phillips screwdriver
  • 2.5mm allen key

1. Turn the machine off and allow it to cool down.

2. After removing the water reservoir and top grate, remove the spring-loaded screw at the top of the unit.20210106_121231

3. Unplug the power cord and sensor wire, and then remove the second spring-loaded screw at the bottom.


4. Underneath the machine, unplug the sensor wire and the waterline tubing. A towel may be handy as there will be some residual water that will leak out of the waterline.


5. Now that the water reservoir holder can be removed from the machine, unscrew the two phillips screws at the bottom of the reservoir holder.


6. On the bottom of the reservoir holder, remove the other two phillips screws. This allows the bottom portion of the reservoir holder to be separated from the top part. 


7. With the bottom portion of the water reservoir holder removed, use a 2.5mm allen key to remove this single screw.


8. Separate the bottom portion, these two tabs can be pushed forward to allow it to come apart.


9. Now that you have access to the hose, work the hose off of the inlet (it will be snug, but it's on by a simple barbed fitting so with some effort it will slide off). At this point, the old tubing can be removed, and the new one can be fed in and plugged in. You'll need 5mm ID X 8mm OD silicone tubing, compatible tubing should be available at any plumbing supply store.
