Troubleshooting Procedures
3. Electronic control board
1. Strainer/flow control (.750 GPM)
2. Improper water pressure
3. Brew Valve
4. Dilution Valve
5. Lime buildup
Perform the above procedure for
testing triacs. If the voltage mea-
sured is very low or zero, then sub-
stitute a control board known to be
in good working order.
(A) Direction of flow arrow must be
pointing towards the brewer.
(B) Remove the strainer/flow con-
trol 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-
ing Individual Components
on page
36. Turn the valve on for 30 seconds
and collect the water dispensed from
the sprayhead. Repeat the test sev-
eral times to confirm a consistent
volume of dispensed water. If not
consistent, check the valve, tubing
and sprayhead for lime buildup.
(A) If dilution is being used on the
inconsistent brewing recipe, test the
Dilution Valve. Refer to
Testing Indi-
vidual Components
on page 36. Turn
the valve on for 30 seconds and
collect the water collected from the
dilution opening. Repeat the test
several times to confirm a consis-
tent volume of dispensed water. If
not consistent, check the valve, tub-
ing and dilution opening for lime
buildup.
(B) Remove the dilution strainer/
flow controland check for obstruc-
tions. Clear or replace.
Inspect for lime buildup that could
block the tank, tank fittings, tubing,
valves and sprayhead.
Spitting or unusual steaming from
sprayhead or air vents. (Water too
hot) (cont.)
Inconsistent beverage level in server.
