Frequently Asked Questions
•What is the resistance value I should expect from a good leak sensor when dry?
When dry, a functional leak sensor should exhibit very high resistance, ideally an open circuit (infinite resistance) as measured with a multimeter.
•How do I test the wiring harness to the leak sensor?
With the dishwasher unplugged, use a multimeter to check for continuity between the connector pins and their respective points on the control board. Also, check for shorts to ground. Any breaks or shorts indicate a wiring problem.
•If the sensor and wiring are good, is the control board the likely culprit?
Yes, if the leak sensor and wiring are verified to be functional, the control board is the most probable cause. The control board may not be interpreting the sensor data correctly, or the internal circuitry related to the sensor input may be damaged.
