Delonghi Magnifica - pump stops after 10 seconds with fault lights My Delonghi Magnifica ECAM22.110.B Bean-to-Cup machine just stopped working. The symptoms are:


Machine starts as normal
Grinder runs and pump runs for exactly 10 seconds then cuts out
Water from steam nozzle also runs for exactly 10 seconds and then cuts out
On the machine, the "water" light is illuminated and the "fault" and "grounds" lights are flashing
Given that this fault showed with hot water from the steam nozzle, I was guessing a pump or flow sensor fault. It turned out to be the flow sensor.

To repair:


Unplug the coffee machine from the mains
Remove the back panel, see here for instructions
Locate the flow sensor:





Unplug the electrical connection
Disconnect the two tubes (noting which goes where)
Remove the flow sensor
Carefully twist the top and bottom to open it
Rinse to remove any particles - mine had some coffee grounds in it which were probably jamming the mechanism
Carefully reassemble the sensor and reattach it
Replace the covers
