5. Water Temperature
6. Low Brew Water Volume
1. Funnel Loading
1. Solenoid(s)
2. Plumbing Lines
3. Water Supply
4. Tank Heater
REMEDY
The BUNN® paper filter must be
centered in the funnel and the bed
of tea leaves leveled by gentle shak-
ing.
Place an empty funnel on an empty
dispenser beneath the sprayhead.
Initiate a brew cycle and check the
water temperature immediately be-
low the sprayhead with a thermom-
eter. The reading should not be less
than 200
°F (93°C). Adjust the con-
trol thermostat to increase the wa-
