settings being altered whilst food is
cooking. Once activated, the sensor
lock prevents the sensors working a
few seconds after a programme has
been started.
– On
The sensor lock is activated. Touch
the sensor next to OK for at least
6seconds to use the functions again.
The sensor lock is then deactivated
for a short period.
– Off
The sensor lock is not active. All
sensors react to touch as normal.
Water hardness
The steam oven is set ex-works for Hard
water. It must be adjusted to local water
hardness to ensure trouble-free
operation and to ensure that descaling
is carried out at the correct interval. The
harder the water, the more often it will
need to be descaled.
