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 pump just makes a noise
(vibrate).
There is probably an air bubble in
the pump supply that prevents the
pump from taking water in.
As a result, there is no water flow,
which causes the flow meter not
produce impulses.
This can occur if the machine has
been in stock for a long period and
the machine is commissioned for the
first time.
Remove the back wall of the machine.
Locate the pump.
Remove the bypass hose from the brass
control valve (see red circle).
Let the air escape from the hose and
put the hose back on the control valve.
It may help to squeeze the supply hose
a few times. Perform these actions while
the pump is running.
Activate the pump in the Service menu
