Hoshizaki KM-515 MAH Evaporator

[Icon KW]

Hi, I have a Hoshizaki KM-515 and the left evaporator is hardly making ice - just a thin layer on some areas. The right evaporator works normally with healthy cubes. The right copper tube has a frozen layer of condensation on it, and the left copper tube has liquid condensation on it, indicating, it's "NOT" as cold as the right side copper tube.

Also, the ice maker takes a LONG time to drop a batch, and then the second batch, it stops with the 3 beep alarm.

The machine is pretty clean and only a couple of years old. I've ran cleaner through it - no visible build up of scale and the lines/hoses are all clean. The float is also clean.

Could there be a blockage in the evaporator tubes?

Thanks for any advice.
