REMEDY
Refill valve – Disconnect the brewer
from the power source and remove
wires from refill valve coil. Check
for continuity across the terminals
of the solenoid coil. If continuity is
not present, replace the refill valve.
If continuity is present, the coil may
be stuck closed. Shut water off to
brewer. Press the ON/OFF switch to
turn off the brewer. Open the faucet
and drain water down in the tank
until flow stops or slows to a trickle.
Attach a voltmeter to the terminals
of the refill solenoid. Connect the
brewer to the power source. Press
the ON/OFF switch to turn the brewer
on. Within five seconds, voltage
should be present at the solenoid
terminals. If voltage is not present,
refer to the wiring schematic and
check the wiring harness.
Substitute a control board known
to be in good working order.
ON/OFF switch must be ON for the
refill circuit to operate. Turn ON.
