Do this first before running the diagnostics:
■Make sure the rinse aid is full. The machine can't dry the dishes without it.
■Start the machine on a normal wash cycle, tub empty and no soap. Listen for the fill cycle to end then open the door and check the water level.
■Close the door and let it wash for about one minute. Open the door and check for suds on the water. If there's suds cut back on the amount of soap you use. Close the door and let it finish the wash cycle.
■Listen for the drain pump/motor to turn on. Before the fill starts open the door and see if all the water is drained out. Make sure the drain hose loops higher than the bottom of the sink before the connection to the drain or disposer.
To invoke the Diagnostics Cycle, perform the following while in standby:
■ Press Start key to wake up control panel.
■ Press any 3 keys in the sequence 1-2-3-1-2-3-1-2-3 with no more than 1 second between key presses.
■ The Service Diagnostics Cycle will start when the door is closed.
■ Invoking Service Diagnostics Cycle clears all status and last run information from memory and restores defaults. It also forces the next cycle to be a sensor calibration cycle.
■ Drain and wash motors will pulsate on and off.
■ Last Run cycles and options returned to default.
■ Last Run Delay returns to the lowest delay increment.
■ Calibration cycle may force an extra rinse to occur prior to final rinse (to assure clear water), then calibrates the OWI and the fill amount during the final rinse.
■ Operating state returns to Standby upon completing or terminating the Service Diagnostics Cycle.
■ The Diagnostic Cycle has 27 intervals and starts in interval 27 and ends on interval 1. The total time is about 25 minutes.
■ Interval 27 turns all the LED's on as a display check. Interval 26 turns off all LEDs during pause prior to displaying error codes.
■ Intervals 25 - 24 - 23 - 22 are for error codes, newest to oldest.
■ NOTE: Some models have replaced "CLEAN" with "COMPLETED"
The Clean (or Completed) LED will flash the error codes in two parts. The Clean LED will first flash the function code, pause for 2 seconds then flash the problem code, pause for 5 seconds then repeat three times unless advanced by Start key.
■ If there are no errors, Clean or Completed LED will stay on solid for 5 seconds.
■ Interval 21 is a 10 second pause and the Hi-Temp LED will be blinking. Press the Hi-Temp key to clear customer history and error codes.
■ Intervals 20 to 3 is the service diagnostic cycle.
■ Intervals 2 and 1 are for any error codes found during the service test.
