Manitowoc Refrigerators - Recent Questions, Troubleshooting & Support

Over filling may be the cause of the problem, water solenoid valve not working, bad float switch, bad timer. If all other sequence check out ok, then I would be looking at the water valve power and capability to shut water off.

Those are expensive machines. I would call a qualified service tech that knows how to work on them.

TXV?

Most likely that is a drain line and should be routed outside v

The seals are defective, either replace the valve or rebuild it with new seals.

Would suggest you contact the factory or search on-line. A B570 is only an insulated storage bin. The door hinges are the only moving parts.

Most common issue for this is an improperly adjusted thickness probe. Locate the screw at the top of the probe and turn it clockwise about 1/2 turn. Wait for the next harvest to determine if it needs more adjustment.

There are a few possibilities. First, water could be leaking out of the sump. You don't note the actual model, so this could be due to a scaled-up dump valve, or a poorly set float valve, depending on the model and age of machine. Check the outlet of the drain line as it's producing. If water is being drained out during production, locate the source and deal with it. If it's being fed hot water, this will occur, as well. Beyond this, you'll need a tech to determine the reason. Most common would be starving txv or improper refrigerant charge.
