Manitowoc ice maker

I have a Manitowoc ECS 018 AL ice maker that i am looking at, it should make 16 nuggets a go, it wasn't making much if any ice.

I have cleaned out the spray heads, descaled it, cleaned the condenser. It seemed to be losing too much water from spray down the bin drain during ice making, water level would drop till there was none to pump and it would harvest some very poor excusses for ice cubes.
Found when the back panel was put back on it pushed the evap forward, which stopped the fingers from shutting again after harvest so sorted this out, then realised it wasn't spray causing the level to drop but the water was running out round the drain bung in the water reservoir, fixed that.

Finally i'm getting to my question, when it goes to harvest, water overflows the reservoir and into the ice bin melting in the process a lot of the ice thats in there. On the top of the tube that goes in the bung in the reservoir is a grey plastic cap with a 3/16" hole drilled in it, should this cap be there???? it seems to slow the draining so it overflows... (I'm wondering if it was fitted in the past by a tech thinking that was where the water was leaking from)

I've never seen one of these before let alone one working correctly so am hopfull for some advice.

Cheers Jon

Thank you Pecmsg,

On page 26 it shows the overflow tube i was wondering about, on the machine i am working on there was a gray plastic cap with a hole in it on top of the overflow pipe, i thought originally it was a factory fitment, but on closes inspection the hole isn't central and it just has the look of a made on site modification.
What i was wondering was has anyone who has worked on this model seen this cap or know if it should be there or not. I haven't seen it on any of the diagrams or parts list i have found.

I have run it last night without the cap and it seems to work much better.

Judging by the condition of the coldstore i was originally called in to look at i wouldn't be at all surprised if the cap wasn't a bodge done by the previous company.

Cheers Jon :)

Throw the gray plug away as you have found and fixed the problem. This is a Mickey Mouse ice mach. and has a very simple process. The water curtain is a critical part and the other place water leaks from the system that is often overlooked
