Heating phase taking very long
The coffee machine heating phase takes a long time.
The appliance door was opened during the heating phase.
If the appliance door is opened during the heating phase, e.g., to fill the water container with fresh water, the heating elements switch off during that time. This means that the appliance does not heat up further. The appliance only heats up when the door is closed.
Close the appliance door during the heating phase.
For thorough and gentle cleaning of your coffee machine, we recommend Miele products which also care for your appliance at the same time.
