TOILET OPERATION CORRECTIVE PROCEDURES
Symptom: Toilet will not flush and water will not enter toilet bowl.
• LED 13 (+5V) off :
Check toilet fuse or circuit breaker.
Check for loose or defective wiring between Control Module and DC power source. Check for reverse polarity.
If all of above check OK, replace Control Module.
• LED 13 on:
Input voltage must be 10V DC or higher.
Check for error codes at LED 10 and LED 11. If showing error, reset Control Module using Mode Switch. If not showing error or Control Module does not reset, go to next step.
• Check following status lights on Control Module:
LED 3 (Valve Closed): If not on, Closed Limit Switch is out of alignment or defective, or related wiring is defective.
LED 9 (Hold Tank Full): If on, replace Control Module.
•Push Flush Handle down (in "Flush" position) – status light LED 6 (Flush) must light up. Then, release Flush Handle, and status light LED 6 should turn off.
If LED 6 did not follow the commands of the Flush Handle, the Flush Switch or related wiring is defective.
If LED 6 did follow the commands of the Flush Handle, go to the next step.

•Mode Switch in "Service" position. Return the switch to the "Normal" position.
•Foreign object prevented the Flush Ball from closing and safety circuit locked the Flush Ball in the open position. Reset the Control Module by putting the Mode Switch in the "Service" position temporarily, then set in "Normal" position. The Flush Ball should close after 2 seconds. If Flush Ball does not close, go to next step.
•Check for error code at LED 11 (Do Not Flush). If showing error, the Closed or Open Limit Switch is out of adjustment or defective, or related wiring is loose or defective.
