The green clean light is flashing. It will not go off even when we press cancel. The wash cycle was not completed. The model # is 665.17283400.

Cycle thru the wash settings. Do all the lights work for the different settings?

The Start/Resume light is flashing

This flashing light indicates that your cycle or start-up was interrupted.
Possible causes: The door opened during the cycle, or the power was interrupted.
To resume operation: Make sure the door is closed, and press Start/Resume.

The Clean light is flashing

You should call for service if the Clean light is flashing and the machine is inoperable. It is normal if the Clean light stays on after the cycle is complete. The Clean light is an indication that the dishwasher has been run and that the dishes inside it are clean. Once the door is opened after the cycle is complete, the light will shut off.

The lights are rapidly flashing

Any key that gets stuck will rapidly flash. Press the key a few times in order to release it or press Cancel.

The Rinse Only light is rapidly flashing

If multiple keys are stuck, the Rinse Only light will flash. Press each key, one at a time, to release the stuck keys, or press cancel.

It is in a delay wash mode.
Disconnect power for 60 seconds.
Re-connect power.
Press the Cancel button.
Press the regular wash cycle and start the dw.

Press STOP/CANCEL to clear the display and completely cancel the cycle

flashes if the washer loses power during a running cycle. The washer does not flash "PF" when it is first plugged in.
Press START to continue the cycle from the moment that power was lost

You can remove the top of the printer to remove and clean the pad or reset the printer and continue without cleaning.

These are the instructions which worked for me on my Canon pixma ip470 and has work on many other Canon models:

1) Close the print head cover, and turn off the printer. While pressing the Resume/Cancel button, press the Power button. (Do not release the buttons. The LED lights in green to indicate that a function is selectable.)

2) While holding the Power button, release the Resume/Cancel button. (Do not release the Power button.)

3) While holding the Power button, press the Resume/Cancel button three times, and then release the Power and Resume/Cancel buttons. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.) During initialization, the LED blinks in green.

4) When the LED stops blinking and lights in green, press the Resume/Cancel button the 4 times. (Each time the Resume/Cancel button is pressed, the LED lights alternately in either orange or green, starting with orange.)

5) Press the Power button. The LED lights in green, and the
selected function is performed. (When the operation completes, the printer returns to the menu selection mode automatically.)

6) Power off then back on and test.

Press these buttons in succession, within 5 seconds: high temp wash, air dry, high temp wash, air dry. If the sequence is entered properly, all of the control panel LED's will illuminate simultaneously. Once this happens, press the cancel button twice. Now you should run a complete cycle again. If the dishwasher actually has a problem, it will fault again (means the unit isn't heating properly). If not, it's business as usual.

You will have to reset the console. To do this, close the door and press these buttons in sequence...

-high temp wash
-heated dry
-high temp wash
-heated dry

...all the lights will turn on briefly and the machine will start a diagnostic cycle. You can press cancel or let the diagnostic cyle finish (1-2 minutes).
You should now be able to run the dishwasher as normal.

If the clean light flashes 7 times, pauses, then repeats...

When the dishwasher doesn't sense a water temperature increase, it will stop working and lock the functions (clean light flashes 7 times, all buttons are non responsive). It does this as a safety in case the element is broken and feeding electrical current into the water.

To resolve this you will have to reset the console. Do this by closing the door and press these buttons in sequence...

-high temp wash
-heated dry
-high temp wash
-heated dry

...all the lights will turn on briefly and the machine will start a diagnostic cycle. You can press cancel or let the diagnostic cyle finish (1-2 minutes).
You should now be able to run the dishwasher as normal.

If the issue returns, you could have a problem with the heating circuit (ie. element, thermostat or wiring). It rarely happens but it could also be the door switch not engaging properly when the door is closed (slightly bend the door latch down making sure it doesn't hit the door when you close it).

I actually had to change the steps a little and this is what I did:

press heated dry
press normal wash
press heated dry again
press normal wash again
wait a few seconds
all the lights should come on
press cancel (should hear pump)
hit cancel again

Started a cycle and began washing.....Thx

call sears, 1-800-4MY-HOME. They have a trouble-shooting department that will get rid of this problem. It is caused by water temperature being wrong at the start of the cycle.... blah, blah, blah. The representative will tell you to push a certain set of buttons in a certain order and that unlocks the dishwasher.

Sorry I don't know the sequence
