Icemaker Matag Performa

My icemaker stopped working but the water on the door works. I have replaced the Puriclean filter, vacuumed out under the frig (which I do regularly) replaced the valve inlet (the major one) Used the dryer on the spout where the water comes into the icemaker…what I am seeing is when I disconnect the plastic water line the water does not move-it doesn’t run out nor does it move backwards…What is the next step…I was thinking maybe a new icemaker but which one do I use…it says use icemaker assessory kit
