Solution
Connect hoses of the water
u
circuit or brewing unit
correctly.
Check everything and replace if
u
necessary.
Connect microswitch correctly.
u
Check water inlet valve.
u
Check filter.
u
Check water flow to brewing
u
group.
Check electrical circuit until the
u
flowmeter.
Check NTC of the
u
corresponding coffee boiler.
Measured value: 10 kΩ at 25
°C.
Check electrical circuit of the
u
NTC.
Check brewing unit for water
u
leakage.
Hoses from the 3rd channel
u
"outlet" not connected to
module; cracks in the hose;
check all hose connections.
When after cold start rinsing:
u
Clean coffee outlet.
