Hi.. let me see if I can help... normally

the water pump runs continuously only during the freeze cycle..

the water inlet valve operates only during the harvest cycle.

The compressor wont operate if the bin control tstat is open or if the high pressure control is open..

The first thing to check is the bin probe.. if you have a multimeter, with the machine unplugged, remove the leads from the probe body or where it connects to the control and check for continuity... if you have continuity... it is closed and is telling the control to make ice... if it open.. ie no continuity...then the probe is bad..

That probe is the main part that tells the machine to make ice...

if the probe is good then we are looking at the main control board.

let me know what you find so I can help further.
