Control is programmed to stop running and not allow any further
cycles if it detects a water heating problem (no temperature
increase detected in heated Main Wash cycle or in 3 consecutive
cycles on the latest software version). Control blinks the Clean
LED 7 times repeatedly and disables the Start/Resume key until
Running Diagnostics clears the control and allows it
to operate again.
The water heating condition
must be corrected or the control will stop
running again. See potential causes below.
Heater circuit problem:
Wire disconnected, open connection or component
in heater circuit.
Faulty heater drive circuit on control.
1. Check operation of heater in Diagnostics cycle.
2. Unplug dishwasher or disconnect power.
3. Check resistance of heater and all components
and connections in the water heating circuit or heat
Door switch not making contact consistently:
Misaligned door latch assembly (which can be
aggravated by high door closure force keeping
strike plate from fully seating).
Faulty door switch (high resistance).
Loose or missing installation anchor screws,
causing tank to shift in cut-out.
Neutral switch on plastic tub models is only in series with
the heater; other loads are not affected.
1. Unplug dishwasher or disconnect power.
2. Measure resistance of door switch contacts while
checking mechanical operation of latch assembly.
Confirm switches not loose from assembly. Check
strike plate and door closure.
Wash pump not pumping water past the heater efficiently.
Foreign object in pump
Clogged pump screen or broken chopper screen
Loose electrical connection in motor circuit. Give me a few to look up the info on the diagnostic . I'll be back shortly.
sorry I didn't get your message until this morning.heres the diagnostic procedure.
SERVICE DIAGNOSTICS CYCLE NOTES
To invoke the Diagnostics Cycle, perform
the following key presses or actions in less than
6 seconds while in standby:
➙ Normal ➙ Heated Dry ➙ Normal
To rapid advance one interval at a time, press the
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 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
Turn on all LEDs immediately upon
receiving entry sequence (even if door open) and
throughout this first interval as a display test.
On numeric time display models, display
the following software information after the initial
Interval 18 - Dishwasher control platform number
("d3" Raptor/Tall Tub, "d2" Cheetah/Briva, "d1"
Rush/Tall Tub, "d0" New Gen).
Interval 17, 16, 15 - Software generation number
(incremented for each release of software to
If flow meter is operating correctly the
control will turn on the Clean LED when flow meter
counts 3 or more pulses anytime during these
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
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 8; execute max. allowed
APFs and turn on Clean LED in interval 7 if bulk soil
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.
I will be back sometime this afternoon. I have to go out of town, let me know what you come up with. thanks, Bryan
