Ok thanks for that ive got it now.
Looking at this model its more then likely going to be a faulty ice maker unit itself at fault here. As if its not making ice its nearly always the ice maker unit itself.
If you wanted you can try a defrost first. As sometimes the water line inside the freezer at the back can ice up and stops the water going to the ice maker. For this you need to empty the freezer and leave it off for 24 hours with the freezer door open and then turn back on and see how it goes from there.
To be honest its quite rare this is the fault but worth a try if you want just in case.
Other then that it will need a new ice maker unit itself. You can either fit yourself or get an enginner in.
Fitting it isn't that bad. Its just 3 screws holding the ice maker to the side. Loosen them and lift the ice maker off and disconnect the wiring block.
Then you can swap it over to the new one.
Other then that if you get an engineer in they will sort it. But as I said its nearly always the ice maker itself at fault.
If you have anymore info just get back to me.
