TROUBLESHOOTING (cont.)
PROBLEM PROBABLE CAUSE REMEDY
Inconsistent beverage level in
server/dispenser
Direction of flow arrow must be
pointing towards the brewer. Re-
move the strainer and check for
obstructions. Clear or replace.
Check operating water pressure to
the brewer. It must be between 20
and 90 psi (138 and 620 kPa).
Test the brew valve. Refer to test
outputs on page 56. Turn the valve
on for 30 seconds and collect the
water dispensed from the spray-
head. Repeat the test several times
to confirm a consistent volume of
dispensed water. If not consistent,
check the valve, tubing and spray-
head for lime buildup.
If dilution is being used on the in-
consistent brewing recipe, test the
dilution value. Refer to test outputs
on page 56. Turn the valve on for
30 seconds and collect the water
collected from the nozzle. Repeat
the test several times to confirm
a consistent volume of dispensed
water. If not consistent, check the
valve, tubing and nozzle for lime
buildup.
Inspect for lime buildup that could
block the tank, tank fittings, tubing,
valves and sprayhead.
Adjust the brew volume as required
to achieve the recommended vol-
ume for each brew cycle.
