Water buildup inside my gold series refrigerator

As far as the icing up sounds like your cross over have ice. Unplug and defrost even on frost free. Should solve both problems

need to clear the drain tube has bend/buildup or debris in it if access to an air compressor in the inside pan where drain line hooks up blow line out to lower pan

Usually there is a drain hose from the freezer to a holding area (like a pan or container) where the water stays until it evaporates. Could be that the drain hose has become disconnected and the liquid is leaking down the inside of the appliance onto the floor instead of being directly into the holding pan.

...

Could be a few things. One could be a bad evaporator fan motor in the freezer section. The fan motor will only come on when the light switch is closed so make sure you hold down the light switch when you check it. Could be a defrost timer or defrost bimetal. You will know because you will have ice buildup on the back wall inside the freezer. Also could be icebuildup in the return air duct. They are located under the drawers in the refrigerator.

Is your fridge compartment temperature in the region of 2 ~ 6 C range. Is your fridge food not going bad. Then dispensor water should be cool. Cool water tank is normally hidden inside fridge compartment. Lowest temp is around 2 ~ 6 C range.

If you keep on taking water rapidly then there is no time for the cooling tank to cool. You are just pushing house water through the water dispensor.

Water valves leak like a leaking faucet sometimes. They just will not close all the way allowing water to bypass the valve and either drip at dispenser or drip and make a mess in freezer. Your model takes a=> 2219592 Water Valve - Dual Outlet

Change the dual water control valve and I believe this will solve this problem, Thanks Sea Breeze

if it is just affecting the upper rack i doubt it is just a plugged spray arm (though i could be wrong). more likely than not you have a blockage on the intake of your spray pump motor. a series of bones, toothpicks, foreign material, etc could be blocking the entrance of the pump causing it to starve for water so to speak.
you will more than likely need to remove the lower rack and spray arm to be able to disassemble the strainer and gain access to the sump.
a complete model number would help bunches to.. alas

On the back of the door directly behind the flapper door , you will see an access cover ... take it off and adjust the tension

Clean out the coils at the very bottom of the refrigerator from all of that lint/dust buildup it makes your system inefficient

Its the clogged defrost drain. I have the same problem. I just cant find the drain
