Hello, Thank you for using this service, I will be helping you with your problem today

can you count the blinks and tell me how many ? is it seven blinks. is it blinking fast or slow ?
Customer: replied 5 years ago.
It is blinking 7 slow blinks pause 7 slow blinks
okay , this means your water isn't heating up correctly , check the heating element in the bottom of the tub. does it look burnt or discolored anywhere around it ?
Customer: replied 5 years ago.
no the heating element looks fine.
okay, heres what the manuals say.

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.

Check If...

Heater circuit problem:

Open heater.

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

dry circuit.

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

Excessive foaming

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.



To invoke the Diagnostics Cycle, perform

the following key presses or actions in less than

6 seconds while in standby:

Heated Dry

➙ Normal ➙ Heated Dry ➙ Normal

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



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

display test:

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

38°C (100°F).


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
