Descaling
Whenever steam is produced, irrespective of the hardness of
the local water supply (the lime scale content of the water),
lime scale is deposited in the boiler. The oven automatically
recognizes when descaling is necessary.
• <Descale now> appears in the text display.
The time interval between descaling depends on the hardness
of the water and frequency of use. If steaming four times per
week at 30 minutes each time, the oven must be descaled—
depending on water hardness—roughly as follows.
We recommend you descale the oven whenever the warning
appears in the text display. Failure to descale the oven will
likely impair the functioning of or cause damage to the oven.
The oven can be descaled with the oven door open or closed.
The oven must be turned off.
NOTE: When descaling, only use the descaler especially
developed for this oven. You may order this from Viking
Range Corporation. With this special descaler, you can
achieve gentle and professional descaling for your oven.
Standard descaling solutions are not suitable as they may
contain foam additives or be ineffective.

Changing the Water Filter
Over time the water filter can get clogged with fine particles
of dirt and lime scale, which are found naturally in water. If the
water filter is blocked, not enough water is being pumped
into the boiler. In this case, <Refill water> and <and press
Enter> appears in the text display even though the water tank
is full.
1. Remove the water tank.
The swing arm rises.
2. Press the swing arm at the
back. The swing arm comes
down again.
3. Hold the swing arm in
one hand. Remove the
water filter with the other
hand. Carefully press the
new water filter onto the
swing arm.
