Remedy
B.O.M. sprayhead #01082.0002 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 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" (upper) position press the start switch and release it. Check the wa- ter temperature 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 op- eration
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 the tank heater.
Check for low voltage.
