Hi,Welcome to Just Answer, My name isXXXXX will be helping you with your appliance issue today.
Can you get us the full model number?
Thanks in advance. Here is what I am able to share.
(1) Affinity 4.4 tub, white
(2) I have some model and seriel #'s but I think they are the bottom storage units
I can't find anything on the other manuals or on the washer.
Yes that is it, your problem is the control board interface, part number one on this diagram, it will need to be replaced, this requires quite a bit of labor and you need to be careful not to break any of the plastic parts on the control assembly because this can be very expensive to replace, if you feel you are not able to do this I would definitely call for service and have somebody replace it for you, the part is $108.49, I tell you this so you will know how much the part is so when you call a technician they don't overcharge you, this happens quite a bit so beware of the price so you do run into this, if you think you can replace this yourself you can order the part at the following blue link,
