Page 20
REMEDY
Make sure sprayhead is present
and holes are clear and unob-
structed.
The BUNN ® paper filter must be
centered in the funnel and the bed
of grounds leveled by shaking gen-
tly.
Disconnect the brewer from the
power source. Remove the warmer
plate and turn upside down to ex-
pose the warmer terminals. Re-
move the two wires. Check for
continuity across the two warmer
terminals. If continuity is not
present, replace the warmer ele-
ment (See page 30). If continuity
is present, reconnect the wires to
the warmer element. Check for
voltage at the warmer terminals.
Turn the warmer switch "ON". The
indicator light will come on. Volt-
age should be present at the ter-
minals. If not, disconnect power
supply and check wiring and
switch.
