Open the door and hold the door switch closed with one hand. Find the button the the icemaker I circled below.
Push this button for about 5 seconds while holding the door switch in. Let me know if it activates and requests water or not.
I fixed it while I was waiting... By!
Ok. If it stops again just let me know. Getting it to request and fill is not a cure. Seeing if it dumps several times will determine if it is fixed or not. I will check back periodically to see if you have posted. There will be a link in your email to this question if you need to come back.
