Our dishwasher is giving us an error code. Code "uo". This appears after about 30 seconds of filling. What is this code telling us?
ANSWER Hello John,
The UO error code indicates the Vent open. While in the wash cycle the main control board does not receive signal from the vent assembly that the vent plunger is closed. The plunger status is sensed with an optical sensor in the vent. Check the wiring between the vent assembly and the main control board. If the wiring is correct then replace the vent assembly 5304467317. If the error still exist then replace main control 154757002.
