Anytime one of the cooling tubes is blocked it forces the cold air from the freezer through the open cooling tube or tubes so you will have spot freeze ups. Suggest you use a flexible wire like a guitar string to attemp to clear the blockage. If you heat the wire with a hair dryer, it will make the job faster.
As far as the unit resetting itself, it could be a preset condition. If the sensor are telling the control board one thing and you are trying to change settings, then the preset conditions could be over riding your commands. Get the cooling tubes cleared and see if things go back to normal.
The water dispenser - could be you have a leak in the water line running into the door or it could be the water depenser itself. Not enough data to tell - suggest you localize the leak. Sometimes flour will tell you where the leak starts.
