Fault

Possible cause

Troubleshooting

Food dries out

(for "keeping warm")

Vapour valve does not close completely.

Moisture must remain in the appliance when food is being kept warm. If the vapour

valve does not close completely, the air in the cooking compartment will become

too dry and the food will dry out.

►

Check the function of the vapour valve. (Page 109)

►

Replace vapour valve if defective. (Page 180)

►

Replace defective vapour valve motor. (Page 181)
