TROUBLE SHOOTING CONTINUED:
POSSIBLE CAUSE
13. Defective brew timer
(WC-604)
14. Defective dump valve
or coil

WIRING DIAGRAM

Make sure the timer is receiving 110 to 120 volts at terminals B and A.
Measure the voltage across terminals 6 and A on the timer when it has
been activated. There should be 110 to 120V going to the dump valve. If
not, then the timer is faulty. Replace timer.
If the timer is functioning properly (step 13); next check the dump valve.
Measure voltage across the two terminals of the valve coil. You should
read 110 to 120 volts. Check also for clogging or lime deposits. Clean
lime or clog if present. Replace valve or coil.
