Brewing unit idle current Even when the brewing unit is not run-
ning, it must consume a minimal
amount of current. If it does not, there
is a fault. This may be due to the brew-
ing unit, the power board or the wiring.
► Check the brewing unit for blockages.
► If the fault persists, contact your service partner.
Brewing unit timeout The brewing unit does not have a
switch for the "home position". The po-
sition of the brewing cylinder is detect-
ed by measuring the current value. The
following peak values are detected: up-
per and lower position
The following timeout is defined: if no
current peak is detected within 10 sec-
onds of a brewing unit movement, a
brewing unit timeout is indicated.
► Contact your service partner.
Water flow error While a coffee product is being dis-
pensed, the flow meter performs fewer
than the defined number of minimum
rotations. It is likely there is a blockage
or partial blockage somewhere in the
water system.
► Check the level of the drinking water tank or the
condition of the mains water supply.
► Check the internal or external drinking water tank
(saturation of the filter reduces the water flow).
► Check whether the upper plunger is blocked or
partially congested.
► Check the grinding setting.
If the grinding setting is too fine, this can inhibit or
completely block the water flow.
► If the fault persists, contact your service partner.
