circuit
Reset the coffee grinder settings by moving the
knob to a higher number. (Always do this with the
grinder running). Push the tank to make sure it is
securely engaged, bleed any remaining air from
the circuit (press “hot water”). Check the
connection and replace the flow meter if
necessary. Check the permanent filter below the
water tank to make sure there is nothing
obstructing the flow of water; clean and replace
as necessary. Check the generator by
disconnecting the inlet water pipe and starting the
pump (in test procedure) to remove the air
pocket.
