5.6 Making ice-cubes
Recommended thermostat setting for ice making is position
between 3 and 5.
Fill the ice cube tray (two thirds of it) with cold water or with any
liquid suitable for freezing and insert the tray into the freezing
compartment. Dry the bottom of the tray, as it may stick to the
bottom of the freezing compartment.
The best method to get ice cubes out of the tray is to hold the
tray under cold tap water for a second, turn it around and slightly
bend it.
