FLOW METER
ERROR
Attention; Flow meter
error does not always
mean that the flow
meter is defect.
When the software
starts the espresso pump
the flow meter must
produce impulses.
Why the flow meter
impulses are not made
or do not arrive must be
investigated.
The espresso pump KW2 is
activated and takes water from the
air break, but the flow meter FL1
does not register water flow.
Check if the flow meter FL1 connector is
mounted correctly.
Check that the connector is not wet or
oxidized. See picture on the left.
Check after which recipe the error
occurs and check if one of below
mentioned dispensing valves are
involved with the problem: DV1 brewer,
DV2 mixer, DV4 hot water recipe.
Replace if necessary.
