TROUBLESHOOTING (cont’d)
SYMPTOM 3. Flush valve will not close.
Condition/Procedure
Mode Switch is in SERVICE
position:
Foreign object prevents the ush
valve from closing and the safety
circuit locked ush valve in open
position:
Check the voltage output to
the ush valve motor at
pins 9 and 10 on the control
module as follows:
Corrective Action
• Return switch to the “Normal” position.
• Reset the control circuit by putting the Mode Switch in the SERVICE
position temporarily, then returning to the NORMAL position. If the
ush valve did not close, go to next step.
• Pull the control module out as far as the control cables will allow.
• Disconnect either the orange or green wire from the Closed Limit
Switch.
• With DC voltmeter test leads across pins 9 and 10, ip the Mode
Switch between the SERVICE and NORMAL positions. If voltage is
present for about two seconds in the NORMAL position, the ush
valve motor or related wiring is defective.
• If voltage is not present, replace the control module.
SYMPTOM 4. Water will not enter toilet bowl during a ush and when the ush handle is raised
or the ush switch is pushed to “Add Water”.
Procedure
Check the “WATER VALVE”
status light while pushing the
"Flush" switch on the control
panel:
Corrective Action
• If the “WATER VALVE” status light comes on, the water valve lter
screen may be plugged with debris, or the water valve or its related
wiring is defective.
• If the “WATER VALVE” status light remains off, replace the control
module.
• If voltage is not present, replace the control module.
SYMPTOM 5. Flush valve will not open when Mode Switch is in the “Service” position but opens
during a normal ush cycle.
Corrective Action
• Replace control module.
