What is your question about the switch? not very clear as to what you are asking.

Check to see how long it stays in the freeze cycle. normally it takes a least 20 minutes to make a batch. If less than that, you are probably loosing water causing an early harvest and almost no ice.

most of the time it is the water pump is going bad. It squeals real loud.

This is a "defrost too long" code. Look for bad thermistor or low refrigerant charge first as these are the easiest and most likely place to start.

Look for a small button on the control board. just press it to reset.

I have found that if the pump runs in the wash cycle but not in the ice making postion, the switch is bad. strange but I have had this happen multiple times.

First thing to check is the float switch. If stuck, it can cause it not to run.

If you are referring to the ice not clearing the evaporator plates, usually the defrost cycle is too short. Check that by watching the machine and when it goes into the harvest mode, see if all the ice comes off. If not, lengthen the cycle.

Not real clear of your question but most machines have the control box in the compressor compartment. It has a switch that shows: Wash, Off, Ice. Your incoming electrical is on the rear of the machine. Hope this helps ya.

if your are referring to a harvest cycle not clearing the plates, there may not be enough heat to clear the plates or the defrost cycle is too short. Usually the first thing to check. start there my friend.

3 beeps means freeze cycle too long. usually it's a stuck float or a water valve leaking most all the time. A low refrigerant level, weak compressor, bad TXV, or a leaking hot gas valve are usually secondary issues but not very common. In rare cases, the evaporator plates can separate from the refrigeration tubes. look at evap plates at the bottom and top and see if they are bowed or odd shaped.

Replacing TXV

First question, why do you need to charge the system? Second is it a remote unit or self contained. Third do you have a set of refrigeration gauges? The best wau is to weigh the proper charge into the machine through the gauges. That varies depending if you are air cooled, water cooled or remote.

The valve that you turn to clean the area in between the plates has a small micro switch. This prevents the compressor from running in cleaning cycle. If the compressor is running, there is another issue.

Is it making ice? Frost on this line is not that uncommon as it is colder than the air around it. Make sure you have good water flow over the evap plates. machine may just need a good chemical cleaning.

REC means recovery. It is trying to make temp and is not. Could be frozen up evap, no fan running, door not closing, issues with the refrigeration system.

with not model or serial numbers, I can only suggest that it may very well be the "bin stat". This is a thermostat that has a sensing bulb that is in the bin and senses the ice when it touches it to shut down the machine. If this is bad, no power goes to the control board. Try jumping this out with a jumper wire and see if the machine comes on.

first, freeze cycle too short because you are loosing water. Water may be leaking thru the dump valve. Look at drain while machine is running and see of alot of water is draining. The dump valve spring may be week or there is trash in the dump valve preventing it from seating properly. drain water first before pulling dump valve apart.

Usually a condition of low water in the tank. Other condition is the float switch is set wrong. Could have clogged water filters causing low water condition.
