Problem
Beverage overflows decanter.
Weak beverage.
Brewer is making unusual noises.
Probable Cause
1. Beverage left in decanter
1. Type of paper filters
2. Coffee
3. Sprayhead
4. Funnel loading
5. Water temperature
1. Solenoid Valve
2. Plumbing lines
3. Water supply
Remedy
The brew cycle should be started
only with an empty decanter under
the funnel.
BUNN® paper filters should be used
for proper extraction.
A sufficient quantity of fine or drip
grind coffee should be used for
proper extraction.
B.O.M. sprayhead #01082.0000
should be used to properly wet the
bed of ground coffee in the funnel.
The BUNN® paper filter should be
centered in the funnel and the bed
of coffee leveled by gentle shaking.
Place a funnel over an empty de-
canter on the warmer beneath the
sprayhead. Place the On/Off brew
station warmer switch in the upper
position, press the start switch, and
check the water temperature imme-
diately below the sprayhead with an
accurate thermometer. The reading
should not be less than 195° F. Ad-
just the control thermostat slightly
clockwise to increase the water tem-
perature.
The nut on top of the solenoid valve
must be tight or it will vibrate dur-
ing operation.
Plumbing lines should not rest 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 ap-
proximately 50 psi (345 kPa).
