with a voltmeter when the "ON/OFF" switch is in
the "ON" position (upper)  and start switch pressed.
Connect  the  brewer  to  the  power  source.  The
indication must be:
a) 120 volts ac for two wire 120 volt models and
three wire 120/240 volt models.
b) 200 to 230 volts ac for two wire 200 volt or 230
volt models.

6.

Disconnect the brewer from the power source.

7.

Reconnect  the  three  pin  connector  from  main
wiring harness to the timer.

If voltage is present as described, proceed to #7
If voltage is not present as described, refer to Wiring
Diagrams and check the brewer wiring harness.

7.

Disconnect the black and white wires from the
solenoid.

8.

Check  the  voltage  across  the  black  and  white
wires with a voltmeter when the "ON/OFF" switch
is in the "ON" position (upper) and the "START"
switch is pressed to the "START" position (lower)
and released. Connect the brewer to the power
source. The indication must be:
a) 120 volts ac for approximately 20 seconds for
two wire 120 volt models and three wire 120/240
volt models.
b)  200  to  230  volts  ac  for  approximately  20
seconds for two wire 200 volt or 230 volt models.

If voltage is present as described, the brew timer is
operating properly. Reset the timer dial as required,
to obtain the desired brew volume.
If voltage is not present as described, replace the
timer.

Removal and Replacement (Dial Timer):
1.

Disconnect  the  timer  socket  from  the  brewer
wiring  harness  and  the  timer  leads  from  the
solenoid valve.

2.

Remove the one #8-32 screw securing timer to
component bracket.
