Hello
SERVICE DIAGNOSTICS CYCLEs
1. To invoke the Diagnostics Cycle,
perform the following key presses in less than
6 seconds while in standby:
Heated Dry ➙ Normal ➙ Heated Dry ➙ Normal
Alternative entry method if user interface is not
functional: Unplug thermistor or OWI sensor
2 times while user interface is unplugged (no IDs
or keys present).
* To rapid advance one interval at a time, press
the Start/Resume key.
* Invoking Service Diagnostics clears all status
and last ran information from memory and
restores defaults; It also forces the next cycle to
be a sensor calibration cycle.
Calibration cycles begin with a “sensor check”
to determine whether the dishwasher has an
OWI soil sensor or not. If the control detects an
OWI, it forces two rinses to occur prior to Final
Rinse (to assure clear water), then calibrates the
OWI during the final rinse.
NOTE 2. Turn on all LEDs immediately upon
receiving entry sequence (even if door open) and
throughout this first interval as a display test.
NOTE 3. On numeric time display models,
display the following software information after
the initial display test:
* Interval 18 – Dishwasher control platform
number (“d3” Raptor/Tall Tub, “d2” Cheetah/
Briva, “d1” Rush/Tall Tub, “d0” New Gen).
* Interval 17 – Software generation number
(incremented for each release of software to
production).
4. Thermistor (temperature sensor)
checks:
* Turn Clean LED on if thermistor is in its normal
temperature range of 17°C–71°C (62°F–160°F).
* Turn sanitized LED on if thermistor is above
37°C (100°F).
NOTE 5. OWI (optical soil sensor) checks:
* Check OWI sensor for the presence of clear
water during the 5 sec. pause in interval 13 and
turn on the Clean LED in interval 12 if clear water
detected.
* Check OWI sensor for the presence of air
during the last 5 sec. of Drain interval 3 and turn
on the Clean LED in interval 2 if air detected.
* Check OWI sensor for presence of bulk soil in
the water during pause interval 10; execute max.
allowed APFs and turn on Clean LED in interval 9
if bulk soil detected.
6. Heater relay must lag wash motor
relay by 1.5 sec. at start-up of heated wash
intervals to avoid simultaneous heater and
motor in-rush current.
