This is a Q unit, maybe 600 lb. Water-cooled head, ten years old.
The operators say: we find it not running in the morning. Bine is not full. We switch it off. We fill it with water from a pitcher. We turn it back on and it runs fine - making ice.
It's on well water. Recently I have replaced the clogged water inlet valve, installed new water filters and rack, and installed a 10 micron pre-filter for well sediment.
The condenser water is unfiltered but the head pressure is always normal. And I have never found it off on the manual-reset HP control.
In the summer they had water pressure problems when lots of people were flushing toilets. But now it is winter, the bar is very slow, hardly anyone uses the toilets, the pressure is steady, and I increased their well pump pressure from 45 to 60 lbs. besides.
Last Thursday I was there and the unit was off on "excess harvest time". It's is spotlessly clean inside but did take it's time dropping ice - more than two minutes. I sprayed the cube molds with silicone and it then dropped the ice Very soon into defrost.
Is there anything else I can do to speed up the ice dropping?
Turning the switch off and then back on resets any board faults. But I just got off the phone with the manager and she claims that simply turning it off and then on agan does not refil or restart the machine.
They say they can only make it re-start to make ice by adding water to the sump by hand.
That makes no sense to me. As I understand it; the control board's water fill function works solely based on power to the machine and the water level sensor - when the level falls: the water valve opens. When the water level touches the sensor: the water valve closes.
What the hell can filling the sump from a pitcher have to do with that?
