Remedy
A clean sprayhead should be used to
properly wet the bed of ground cof-
fee in the funnel.
The BUNN
®
paper filter should be
centered in the funnel and the bed of
ground coffee leveled by gentle shak-
ing.
Empty the server, remove its cover,
and place the server on the warmer.
Place empty funnel over the server
entrance, with ON/OFF switch in the
"ON" position press the start switch
and release it. Check the water tem-
perature immediately below the
sprayhead with a thermometer. The
reading should not be less than
195˚F(91˚C).
The nut on back of the solenoid
must be tight or it will vibrate during
operation
Plumbing lines should not be rest-
ing on the counter top.
(A) The brewer must be connected
to a cold water line.
(B) 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 heat-
ers.
Check for low voltage
