Service Diagnostics Cycle Notes
1 To invoke the Service Diagnostics cycle, perform the following while in Standby:
■ Press START/RESUME to wake up control panel.
■ Press any three 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.
■ To rapid advance one interval at a time, press the START/RESUME key. Rapid advance may skip sensor checks as some checks require two
complete intervals.
NOTE: While you are in the Diagnostic Cycle, the Start/Resume feature is turned off (for example, Auto Resume after door interrupts) and the Start/
Resume key becomes an individual advance key.
■ 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 nal rinse (to assure clear water), then calibrates the OWI and the ll amount during the
nal rinse.
■ A tone will play when Service Error 1 is displayed.
■ Operating state returns to Standby upon completing or terminating the Service Diagnostics cycle.
2
Turn on all LEDs immediately upon receiving entry sequence (even if door is open) and throughout this rst interval as a display test.
3 Diverter will be on continuously in interval 14. In all other diverter intervals, diverter will only be on until it reaches the intended position for that interval.
4 Press HI TEMP key in this interval to clear customer error history.
■ If Hi Temp key does not respond, the control panel is in Sleep Mode. Open and close the door to wake up the control panel and then press HI TEMP
to clear the customer error history.
5 Thermistor (temperature sensor) checks - turn clean LED on if thermistor is in its normal temperature range (32°F to 167°F [0°C to 75°C]). Turn sanitized
LED on if ll temperature is above 85°F (30°C).
6
OWI (optical soil sensor) checks:
■ Check OWI sensor for the presence of water during the 5-second pause in interval
16 and turn on the Clean LED in interval 15 if water is detected.
■ Check OWI sensor for presence of bulk soil during pause interval 13 and turn on the Clean LED in interval 12 if bulk soil is detected.
7
DC Fan Motor is on during upper rack washing intervals.
8
Turn off all LEDs during pause prior to displaying error codes.
9
Pause to allow for cold rst ll detection.
10
■ Lower spray arm (LSA) models identied by nger-shaped sensor in tub protruding from bottom left side of sump.
■ Check for LSA motor and sensor during interval 10 according to table below or look for error code F9E4 at end of service cycle.
Interval 10 (4 min lower wash): diagnostic details for LSA models
Minute #1:
LSA rotates CCW
Minute #2:
LSA rotates CW
Minute #3:
LSA rotates CCW
Minute #4:
LSA rotates CW
LSA motor and sensor status indication given during 3rd and
4th minute of interval.
Clean LED lit to indicate LSA
motor status good.
Clean LED lit to indicate LSA sensor status good.
NOTE: Inoperable LSA motor will also cause LSA sensor to indicate bad status. See 9-4 Error Code Table to diagnose.
■ Interval 3: LSA moves to Home position after drain is completed. Home position = LSA approximately 5° clockwise from 12 o’clock.
11 Sanitized LED turned on in this interval to indicate that the salt level reed switch is closed.
