Descale; Appliance Cleaning Tips - Thermador Professional Series Use And Care Manual

Descale

You will need to descale the steam oven at regular
intervals. Once you have set your water hardness level
(see page 60), the steam oven display will automatically
inform you when descaling is needed.
Water hardness
1 – softened Unlimited, no message
2 – soft 400 hours
3 – medium 200 hours
4 – hard 100 hours
5 – very hard 70 hours
If the number of hours of operation is exceeded, the
"descale needed" message will be displayed each time
when a new heating mode is selected. Select enter to
continue. After the descaling operation is finished, the
operation hour counter will be reset and the message will
no longer be displayed.
You can start descale only when the oven is set to off and
is completely cooled down. Once descaling begins, it
should not be interrupted. It is very important that all rinse
cycles are completed.
NOTE: Descaling requires 3 start/stop cycles to complete
its operation.

Appliance cleaning tips

9 CAUTION
Avoid cleaning any part of the range while it is hot.
• The porcelain enamel finish is acid resistant, but not
acid proof. Acidic foods, such as citrus juices,
tomatoes, rhubarb, vinegar, alcohol or milk, should be
wiped up and not allowed to bake onto the porcelain
during the next use.
• The heating elements in the oven do not require
cleaning. The elements burn themselves clean when
the oven is in use.
When cleaning this appliance:
• Use the mildest cleaning procedure that will do the
job efficiently and effectively. Some cleaners of the
same type are harsher than others. Try on a small
inconspicuous area first.
• Always rub metal finishes in the direction of the polish
lines for maximum effectiveness and to avoid marring
the surface.
• Use only clean soft cloths, sponges, paper towels,
fibrous brushes, plastic, non-metal or steel wool soap
pads for cleaning and scouring, as recommended on
the chart.
• Most exterior parts of this appliance can be cleaned
with hot sudsy water (except the various items
specifically identified otherwise). When rinsing is
required, rinse thoroughly.
• Always wipe dry immediately to avoid water marks.
• DO NOT USE CHLORINE BASED CLEANERS.
