In the event of soiling, the milk flask sensing function cannot work properly.
Clean the milk flask thoroughly. Proceed as follows:
Please clean the stainless steel flask with hot water after use to remove any residual milk.
Rinse the handle under running water and then clean it thoroughly with a clean damp cloth to remove any milk residue.
If the milk pipework in the lid is clogged, clean it under running water using the cleaning brush. Insert the brush into the milk pipework. Move the cleaning brush back and forth as far as it will go until all milk residue has been removed.
Pay particular attention to the handle, the intake tube, and the thin metal rod between the tubes when cleaning. Rinse the tubes under cold running water. Then leave the tubes to dry.
Also check whether the gold contact on the right in the door (milk jug opening) is clean. Clean it if this is not the case.
Do not fill the stainless steel milk flask up to the neck of the flask; instead, fill it to max. 1/2" to 1" (2 cm to 3 cm) underneath this.
