Care and maintenance

Descaling

Whenever steam is produced, irrespective of the

hardness of the local water supply (i.e. the

limescale content of the water), limescale is

deposited inside the steam generator.

The time interval between descaling depends on

the hardness of the water and frequency of use. If

steaming 4×30 minutes per week, the appliance

must be descaled (depending on water hardness)

roughly as follows:

Water hardness

Descale after about

Very soft

18 months

Medium

9 months

Very hard

6 months

The appliance automatically detects when

descaling is necessary and when this happens the

Descale light stays on. If the Descaling procedure

is not performed, some cooking cycles after the

Descale light starts to flash. If once again the

Descaling procedure is not performed, some

cooking cycles after the oven functioning is

blocked, the Descale light stays on and the display

shows “CAL” blinking.

IMPORTANT NOTE: Failure to descale the

appliance will likely impair the functioning of or

cause damage to the appliance.

Suitable descaling solutions

For descaling, use and adequate descaling

solution.

Warning! Do not use vinegar or vinegar-based

products as they can cause damage to the

oven’s internal circuit.

Traditional descaling solutions are not appropriate

because they can contain foaming agents.
