REMEDY
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 15. 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 bypass is being used on the incon-
sistent brew, test the bypass valve.
Refer to test outputs on page 15.
Turn the valve on for 30 seconds and
collect the water collected from the
funnel. Repeat the test several times
to confirm a consistent volume of
dispensed water. If not consistent,
check the valve, tubing and fittings
for lime buildup.
Inspect for lime buildup that could
block the tank, tank fittings, tubing,
valves and sprayhead.
Adjust the brew volume, calibrate
sprayhead and bypass as required
to achieve the desired volume for
each brew cycle.
