Primary Source: Wiring.
Action: Check the valve harnesses are correctly fastened to the valves and
the motor control module or the pins are not bent backwards.
Secondary Source: Water Valves.
Action: Measure the resistance of the cold and hot valve coils.
Tertiary Source: Motor Control module.
Action: Replace the Motor Control module.
