Scotsman MXG 328 Icemaker cubes not falling into bin

[nike123]

I have some strange problem with this Icemaker.


Cubes are piling in Ice tray.

I have descaled evrything. Icemaker is leveled perfectly. Tray is not that much sloped as appears at drawing above, but slope is present.
Cubes are off perfect shape.
Water hardnes is around 200 ppm.
What is interesting, everything is same as before and jet, problem has occured aparently out of noting.

Any tought of what could cause ice cubes jamming on slope?
My only logical tought is that somehow surface of ice tray slope is eroded by limescale sand and needs polishing. Or I did not removed all limescale from surface, even if it apears perfectly clean and smooth.

Now when I reverse film backward, problem has occured after i made adjustment on water regulating valve on previous call. It has been stuck open even at off cycle, and after flushing it by lifting with two screwdrivers, it started to close again in off cycle, and I made adjusment measuring with my CAT S60 termal camera at liquid refrigerant pipe exiting from heat exchanger. I adjusted at 41˚C.
Is that to hot, and that could influence cube in harvest cycle in such way that is less slipery?
That is temperature of subcooled liquid. Therfore saturation temperature is somewhat above that. Manual states 17 bar for condensation pressure.

have you checked tray is fitted correctly

[nike123]

Yes I have!

I have been again there and made correction of water valve from 19 Bar (44˚C CST) to 17 Bar (39˚C CST) as per manufacturer specification, but noting has changed.

Here is video of how cubes are piling!

I had this issue and there are little bleed holes at the back of the top tray that allows a flow of water from back of slide to front when harvesting so helping ice to move , these little bleed holes were blocked .

Can you adjust the slope of the tray?

[nike123]

Hi Chemi! It is not possible to adjust slope. Slope is defined by shape of plastic parts.

Hi Joe!
Did you saw video I posted? I think that water is flowing correctly. If you still think that is probably incorrect, please advice. Thanks for your input.

[joe-ice]

The pump stops in harvest and the top tray refills with water , at the back of that tray there are bleed holes that allow a stream of water to flow down along the ice chute to carry the cubes out , you can see it represenented in the top diagram as an opening at the back of tray , in my case these bleed holes were blocked and gave same symptoms as you have now.

Thanks brother! That is precious!
I will definitely check that, and post findings.

Happy new year my friend.
I never mix good whisky with ice...

[nike123]

Thanks Chemi for that manual. After I downloaded it I founded same in my Scotsman folder! Who would taught that!

I never used ice since I started to work with Icemakers!

Happy new year to all my fellow fridgies! And I definitively recomend Whisky without rocks!
