REMEDY
Inspect the tank assembly for ex-
cessive lime deposits. Delime as re-
quired.
Refer to Service - Brew Solenoid
Valves for testing procedures. See
pages 16 or 17
A seven-hole stainless steel spray-
head must be used for proper ex-
traction.
With the "TEA/OFF/COFFEE" Switch
in the "COFFEE" position, place an
empty brew funnel on an empty
decanter beneath the sprayhead.
Initiate brew cycle and check the
water temperature immediately be-
low the sprayhead with a thermom-
eter. The reading must not be less
than 5°F (3°C) below set tempera-
ture. Adjust the temperature setting
to increase the water temperature.
Refer to Adjustments and Optional
Settings. See page 7
®
BUNN paper filters must be used
for proper extraction.
The BUNN ® paper filter must be
centered in the funnel and the bed
of tea leaves or coffee grounds lev-
eled by shaking gently.
The brew funnel should be cleaned
thoroughly before each brew cycle
to lesson the chance of tea leaf par-
ticles clogging the funnel tip.
