REMEDY
Repair or replace leaky valve
BUNN paper filters should be used
for proper extraction
Check sprayhead
The brew cycle should be started
only with an empty server under
the funnel.
Adjust the brew volume, calibrate
sprayhead and bypass as required
to achieve the desired volume for
each brew cycle
The mounting screws on the so-
lenoids must be tight or they will
vibrate during operation
Plumbing lines should not be resting
on the countertop.
The brewer must be connected to a
cold water line. Water pressure to
the brewer must not be higher than
90 psi (620 kPa). Install a regulator
if necessary to lower the working
pressure to approximately 50 psi
(345 kPa).
Remove and clean lime off tank
heaters.
