Test Procedure.

1.Disconnect the brewer from the power source.

2.Disconnect the polarized, three pin connector from the brewer wiring harness and rotate the brew timer dial fully counterclockwise.

3.With a voltmeter, check the voltage across sockets P2 & P3 (white and white/red wires) of the female connector when the "ON/OFF" switch is in the "ON" position (upper). 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 240 volts ac on two wire 200 volt or 240 volt models.

4.Disconnect the brewer from the power source.

If voltage is present as described, proceed to #5. If voltage is not present as described, refer to the Wiring Diagrams and check the brewer wiring harness.

5.Check the voltage across the sockets P1 & P2 (blue and white wires) of the female connector 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 240 volts ac for two wire 200 volt or 240 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 #8

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

8.Disconnect the black and white wires from the solenoid.

9.With a voltmeter, check the voltage across the black and white wires when the "ON/OFF" switch is in the "ON" position (upper) and the "START" switch is pressed to the "START" position 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 240 volts ac for approximately 20 sec- onds for two wire 200 volt or 240 volt models.
