I have brought a ebder 5 plus after I had an ender 3 Pro. I was printing fine on it for months no issues what so ever, until a few months ago. No filament was coming out no matter how many times I cleaned the tube, the hot end and the nozzle. In the end I brought a whole new tube and hot end and now it's printing. The problem is when it prints the infill doesn't seem as strong as it did and the print seems to come apart half way through printing. I have tried on smaller parts I.E. stand for my TCG graded cards and they come out fine the problem is when i start printing bigger parts. All the settings are the same on it all. I can send photos if it helps.
