Water dispenses when icemaker fills

Water comes out of the water dispenser when the icemaker fills with water. Also, water continuous to dispense after releasing the paddle with a noise coming from inside the fridge. It sounds like it’s coming from the tubing from behind the drawers. I have replaced the water valve and water filter already. Flushed the water line a couple of times already. I tested the valves already and they seem to stop dispensing water as soon as the paddle is released. But when connected to all the water lines, the problem persist. I read something about replacing the diodes but I have trouble finding the parts.
