By pressing any of the six buttons for drink selection the present error will be
reset as a result of the machine restarting. For example, this might rectify
errors caused by temporary disturbance in the machine´s water supply.
7.2 Error indicators
7.3 Resetting overfill protection
This only applies to machines that are
directly connected to a mains water supply.
The machine is equipped with an overfill protection from
the heater tank, which blocks the inlet valve (1, figure 24)
in case the heater tank is filled over a pre-determined level
of water.
The overfill protection’s primary purpose is to protect
against major water leakage, which can occur if the ma-
chine is permanently connected to a mains water supply
and the water level sensor does not function correctly.
The overfill protection can be triggered if the machine is
moved or transported with water in the heater tank. The
machine’s tanks must always be drained prior to transport.
