3.With a voltmeter check the voltage across sockets P2 and P3 (black and red wire) of the female connector on the main wiring harness when the "ON/OFF" switch is in the "ON" (upper) position. Connect the brewer to the power source. The indication must be 230 volts ac.
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 diagram and check the brewer wiring harness.
5.With a voltmeter check the voltage across the sockets P1 and P2 (blue and black wires) of the female connector on the main harness when the "ON/OFF" switch is in the "ON" (upper) position and the start switch pressed. Connect the brewer to the power source. The indication must be 230 volts ac.
6.Disconnect the brewer from the power source.
7.Reconnect the three pin connector from the main wiring harness to the connector on the timer.
If voltage is present as described, proceed to #8.
If voltage is not present as described, refer to the wiring diagram and check the brewer wiring harness.
8.Disconnect the black and white wires to the swing arm switch and pump leads.
9.With a voltmeter check the voltage across the black and white wires when the "ON/OFF" switch is in the "ON" (upper) position and the start switch
pressed to the start position and released. Connect the brewer to the power source. The indication must be 230 volts ac.
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:
1.Disconnect the male connector on the timer from the female connector on the main wiring harness.
2.Disconnect the timer leads from the swing arm switch lead and pump lead.
3.Disconnect the three pin connector from the HALF/ FULL batch selector switch to the three pin plug on the brew timer.
4.Remove the two
5.Position new timer on the component bracket and secure with two
6.Refer to Fig. 30 and reconnect the wires.
