I'm trying to find a solution for a frequent failure in a glass still in the factory I work in and I haven't been able yet. I'm posting it here to see if some of you can help me.
The still had a problem with a leakage in one of the valves, I'm pretty sure it's the fill valve. We sent it to be repaired because it's difficult for us to buy a new spare valve for now. The leakage was fixed, but now it stops after some minutes of work, with the Power and Clean LEDs flashing, and drains the boiler. The manual says it happens because the thermistor got exposed and the constant level device lost the water level. We checked the valve, the tubes, everything—I think—but couldn't find anything strange and it keeps failing.
I saw that the orifice that allows the fill flow to pass when the valve opens is really small, thus causing a really small flow. But I think that's the way it always worked. Could it be a faulty thermistor? Or definitely an obstructed tube that we've missed?
It's been two weeks now and it's difficult to keep the processes going like this.
