•Remove the connector at the motor and take measurements as shown in the following table.
Recirc to Neutral | 10 - 12 Ω | RD to WH |
Drain to Neutral | 10 - 12 Ω | YL to WH |
Recirc to Drain | 20 - 25 Ω | RD to YL |
•If the resistance is much higher than shown, replace the pump motor.
•If the resistance at the pump motor is correct, there is an open circuit in the wiring between the motor and the motor controller. Repair or replace the lower wiring harness.
•If the pump motor windings and motor controller are OK, repair or replace the pump.
