Problem: Water Not Flowing From Sprayhead. - Curtis GEM-120A Service Manual

GEMINI 120A
PROBLEM: WATER IN TANK DOES NOT GET HOT OR WATER TEMPERATURE TOO LOW
POSSIBLE CAUSE
10. Defective thermostat

PROBLEM: WATER NOT FLOWING FROM SPRAYHEAD.

POSSIBLE CAUSE
11. Water level is too low
in heating tank
12. Defective brew switch
(item #41)
13. Defective timer (item #2).
14. Burned out dump valve
coil (item #34)
Thermostat may be cutting off before the water temperature reaches
operating temperature. Do not try to reset the thermostat. Replace it.
Check water level in tank. If water is not flowing into the tank, re-
view steps 1 thru 4, previous page.
Check the continuity between terminals 5B and 4B when the BREW
switch is pressed. If there is no continuity, replace the switch.
Make sure the timer is receiving 110 to 120 volts. You can verify
this by taking a reading with your meter at the end of the YELLOW
wire on terminal 5B of the ON/OFF switch and at terminal N of the
timer. When the timer is activated by the brew switch, you should
read 110 to 120 volts across terminals NO and N of the timer. The
RED wire on terminal NO supplies power to open the dump valve.
If no voltage is present, replace the timer.
If the timer works when the brew switch is pressed, then check the
dump valve using a voltmeter on the terminals. If it shows 110 to
120 volts but no water flows through the valve, clean out the valve
or replace the coil.
