My coffee machine has recently stopped frothing milk when attaching the milk container to the coupling carafe. It will send water through the milk contain I select clean but if the nozzle is to froth, it stalls at ‘milk preparation underway’. So, it will pump water to clean the container but not steam to suck / froth milk.
It will dispense hot water using a different attachment connected to the coupling carafe.
It will still dispense coffee via the main nozzle for the machine.
I’m confident I can take it apart, I just don’t know which bit I need to replace.
From the delonghi website, it looks like the primary replacement parts are:
solenoid valve
tco irt
regulator
pump
motor
heating element
coupling carafe
All help appreciated. Thanks.
