I realize that you have tried, unsuccessfully, to reset the the dispenser board or even the refrigerator but here's some information that may help.
Here's is the [document|32023|mini manual] for your refrigerator model.
Enter the diagnostic test mode as shown in the manual and then exit it by selecting test mode 00 16 or simply exit the test mode by power cycling the refrigerator i.e. turn power off, wait ~1 minute and then turn it on again. This resets all the boards in the refrigerator.

If the dispenser is still no good, use the diagnostic tests to check for any fault codes stored (00 00) or to check the dispenser version test (00 18) to see if the [https://www.searspartsdirect.com/model/3kmpms1dbh-000432/ge-dfe28jmkles-bottom-mount-refrigerator-parts|dispenser control board] (part #193 dispenser door diagram) is communicating OK with control board or the dispenser self test (00 02).

If still no indication of what is wrong run all the tests pertaining to the dispenser functions to hopefully find out what's wrong.

If you do find a faulty part use the parts supplier's website to locate the part in the parts diagrams to find the part number for the part. Once you know the part number, search online using the ''part number only'' to find suppliers that suit you best.
You may want to have some towels and containers handy if the dispenser functions are still the same as you have described, when doing the tests ;-)
