Hotpoint Fridge Freezer Water,Ice Buidup Bottom

I had a similar issue lat year. Thankfully it didn't involve taking things apart like you had to endure. Mine had a removable plastic tube under the fridge with a trap curve. The defrosted water would drip into a pan underneath that was right under the coils and fan, causing it to evap off. The plastic tube was clogged causing the same problem inside that you had.

Being cool is a necessity in a clown world that is intent of burning lol cheers and good luck….

what an absolutely shitty design...
