B2 Coil Dosing test. The dosing pump of the coffee
pack action should be clearly audible.
Place a cup under the coffee outlet and clean the
trough afterwards.
LED test. Verify that every LED is properly
functioning.
Heating element/relay test. When actuated the
relay will produce an audible ‘click’.
Peltier test. Measure the in/output voltages over the
related pins/connectors. (When the Peltier element
is activated, a change of fan operation is audible)
The Peltier element will switch off for 3 seconds
after it has been activated.
Valve test. The rear outlet valve (coffee) should
open for 1 second. Place a cup under the coffee
outlet.
Valve test. The front outlet valve (hot water) should
open for 1 second. Place a cup under the hot water
outlet.
Valve test. The water inlet valve should open for 1
second. When actuated the valve will produce an
audible ‘click’.
It is possible that too much water flows
into the boiler due to repeated inlet valve
testing. This may result in overflowing!
Allow time to reset.
