Customer Question

I have a: KENMORE ELITE DISHWASHER-model # 665.12789K311. I have been on here before and was advised to replace the following parts: control board (twice), circulation pump, fill valve, float switch and lever. All of the replacement repairs went well. However minutes into the wash cycle,the wash light will flash on and off never progressing through the rest of the cycle. I did let it go to see what would happen and water starts to seep out the door. What is the issue? What is the solution?

When the unit is leaking is the bottom sump full of water and overflowing?

And you say you have replaced the control board (twice) have you replaced the console/keypad assembly? or just the electronic control board.

Customer: replied 2 months ago.
Just the electronic control board...don't know if sump is full or not...just a little leaking around door. The only way to drain completely is to touch the drain button on the key pad. The keypad works fine
Expert:  Whrlp Master Tech replied 2 months ago.

ok when it starts to leak you will need to open the door and look down in the bottom sump area to see if it is full and overflowing.

And it is the WASH light that blinks and not the clean light correct? need to make sure!!

Customer: replied 2 months ago.
OK...now I know what you mean...Yes the bottom of dishwasher is full of water...And since it is in the wash cycle, it is the washing light that flashes
Expert:  Whrlp Master Tech replied 2 months ago.

ok and since the sump is full of water if you press cancel once the unit will go ahead and drain all the water out correct?

Customer: replied 2 months ago.
correct
Expert:  Whrlp Master Tech replied 2 months ago.

ok and when you start the dishwasher as normal after the unit fills with water (first 2 min) do you hear the wash pump circulating the water in the unit?

Customer: replied 2 months ago.
but as the wash lights begins to flash on and off it sounds like to me it stops then back on
Expert:  Whrlp Master Tech replied 2 months ago.

ok can you give me the circulation pump part number that you replaced please?

Customer: replied 2 months ago.
Tyler Z. from this website had me order part # WPW10314568 Pump and # W10813313 control board
Expert:  Whrlp Master Tech replied 2 months ago.

ok those are the correct parts for this model number of unit!

When it stops and comes back on is the coming back on the display or the entire unit?

Or better questions when it comes back on do you hear the circulation pump motor running?

Customer: replied 2 months ago.
well sounds like to me the entire unit. but the machine is so quite its hard to really tell.yes you hear it swish again
Expert:  Whrlp Master Tech replied 2 months ago.

ok and when it does come back on and then stops again your not touching the unit at all correct?

And when it shuts off the entire console goes blank correct?

Customer: replied 2 months ago.
correct and correct...the last time I tried to wash, I pulled codes like Tyler told me and it pulled the code for the float switch, which is what I replaced with the lever.
Expert:  Whrlp Master Tech replied 2 months ago.

ok if it is going blank and when it comes back on it just starts right back up on it`s own you do not have to do anything correct? and does it seem to start back up in the same place that it stopped in?

Customer: replied 2 months ago.
correct and yes....it never progresses through the entire wash because after about an hour (which is way to long on a quick wash) or I notice water starting to leak out the door not from underneath I tap the cancel button to fully drain
Expert:  Whrlp Master Tech replied 2 months ago.

ok and have you opened the junction box under the unit on the right front corner to make sure that you do not have a loose electrical connection?

Customer: replied 2 months ago.
everything is fine
Customer: replied 2 months ago.
No loose wire nuts and everything protected with the waterproof wrapping and back in the metal case
Expert:  Whrlp Master Tech replied 2 months ago.

ok so then the next step is to test the voltage to the control board while the unit is running and when it shuts off.

Test on the P4 connector test P4-1 White to the P4-2 black and when it shuts off see if you are still getting the 120 volts A/C to the control board.

Customer: replied 2 months ago.
Ok..
I will have to wait until my husband gets home from work for that one...he is the licensed electrician..I will update when he tests it.
Expert:  Whrlp Master Tech replied 2 months ago.

ok if you do loose it then the issue has to be between the junction box and the control board .

if your not loosing the 120 volts then check the door switch and door switch connections on P9 terminal on the control board.

Customer: replied 2 months ago.
We are losing the power in the wash step. I've checked the connections from the junction box to control panel and see no issues. One thing that I did notice is that when we skip to the drain step we aren't losing the power during this entire step. It would only stand to reason that we should loose power if there was an issue with the incoming power. Could there be an issue with the control panel just on the wash cycle alone? And if so is it something that could be replaced.
Thanks
Expert:  Whrlp Master Tech replied 2 months ago.

the water circulating motor is entirely different from the drain motor.

The circulation pump motor pulls more amperage+ power then the drain pump motor.

And you have already replaced the control board and still have the same issue, so very unlikely it is a issue with the control board ,I still suspect a loose connection to the control board ,so it will be either one of the door switches or on the thermal fuse on the control board.
