Water inlet
If, during a certain period, no water is recognised in the evaporator on filling, the supply of water is
discontinued and the clear text display will indicate “Fill up with water”. The following may be the cause
of a faulty water supply:
•
no water or too little water in the water tank
•
a faulty supply pump or hoses which are kinked or defect
•
a defect or scaled level sensor
5.4.2
Emptying
In the case of all of the operating modes, emptying is carried out automatically after the OFF button has
been pressed or after the cooking time has expired or after completion of steam dissipation, apart from
during pure hot air operation.
Firstly the water temperature in the evaporator is determined, and if this exceeds a certain level, water
is then pumped out of the water tank into the evaporator by means of the supply pump, up to level
recognition by the level sensor, plus a certain follow-on time. This procedure is carried out for the
purpose of thermal protection of the discharge pump. Pumping off the water with the discharge pump is
also regulated by means of level recognition by the level sensor and a certain follow-on time. Should
emptying of the evaporator not be carried out within this maximum period of time, two more attempts will
be made. Should it still not be possible to pump off water, the clear text display will indicate “contact F8
service” (emptying faulty).
An essential marginal condition for pumping off the water in the evaporator is a water temperature below
a certain level. Should it not be possible to cool the water in the evaporator down to this temperature –
because there is insufficient water in the water tank or because the water in the water tank is too warm
– the water will not be pumped off. It will only be pumped off when it has cooled itself down to this
temperature (this may well take more than 30 minutes!). The appliance is still ready for operation during
this period. During this cooling-down process, the clear text display will indicate “water is being pumped
off”.
Should, shortly before completion of steam operation, a completely full water tank be supplied with more
water, the water tank may become overfilled on pumping off.
