Service Diagnostics Cycle
Service Diagnostics Cycle Notes:
Customer Cycle Operation
To q ui c k l y adv an c e thro u g h customer cycles, invoke the Rapid Advance
mode by pressing HIGH TEMP - HEATED DRY - HIGH TEMP - HEATED DRY,
after starting the cycle. Then, press START/RESUME to advance through
cycle intervals.
NOTE: Rapid Advance mode is automatically enabled in the Service
Diagnostics cycle but must be manually invoked in customer cycles.

1 To i nv o k e the Di a g nostics cy c l e , p e rfor m t h e f o llowing wh ile
in standby:
■ 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.
■ To r a p i d a dvance 1 in te rval a t a time, pre ss t h e S tart/Resu me k ey.
Rapid advance may skip sensor checks as some checks require
2complete 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 interval 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 Final
Rinse (to assure clear water), then calibrates the O.W.I. and the fill
amount during the final rinse.
■ Operating state returns to Standby upon completing or
terminating the Service Diagnostics Cycle.
■ Reference the “Service Diagnostics with Error Codes” section
for details.
2 Tur n on a ll LEDs i mm ed ia te ly upon receiving the entry sequence (even
if the door is open) for 5 seconds as a display test. Turn off all LEDs for
1 second prior to reporting customer error history.
3 Diverter will be on continuously in interval 14. In all other diverter
intervals, diverter will be on only until it reaches the intended position
for that interval.
4 Press HI TEMP key in this interval to clear 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 fill temperature is above 65°F (18.3°C).
6 OWI (optical soil sensor) checks:
■ Check OWI sensor for the presence of water during the 5-sec.
pause in interval 16 and turn on the Clean LED in interval 15 if
water 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 detected.
7 DC fan motor is On during upper rack washing intervals.
8 Tur n on S an itize d LED in t hi s in terva l to indicate that the salt level reed
switch is closed.
9 Tur n o n Clea n LED in th is i nt er va l to indicate that vent current
is detected.
