your comment of ice melts to fast is directly related to the ice collected in the bin. 1. check ice formation. is unit level? 2. measure water temp/air temp.

Example caluculate 24 hr prodution
1.measure time of one complete cycle
sample:
Divide 24 hr/cycle time (1440 min)
time= 15min collected ice weight=5.5 lbs
1440/15 x5.5=96 96x5.5=528lbs per 24/hr.

Also check your water valve should be off during ice making mode. SMALL AMOUNT of water can cause no ice or low production levels at harvest.
room temp and bin condition at the bin boor can contribute to melting ice.

There are a couple of things to check. The machine must be level. You can remove the front cover and the plastic sheet that covers the plate where the ice is made. Check to see that the water is flowing from the manifold at the top of the plate. You may have to pop the hose off the end of that manifold to clean the water holes out. It must flow evenly over the plate. Probably the most common problem is the radiator coil there the fan draws air through is clogged up so that it can't dissapate heat properly. You should be able to feel a lot of hot air moving through the coils. The fan cycles on and off periodically to maintain a certain pressure in the freon. That is normal. Clean the fan coils and level the machine.

    the water flows evenly over the plate.
    The bin and ice machine is level.
    the problem is the ice seems to not be freezing hard enough too maintain volume. it melts too fast to fill my 250 lb.bin
    thanks for you suggestions though

Won't make ice


The bin should fill up and the machine shut off in 24-36 hours from time it is turned on. If not the condenser coil may be dirty.
1.Clean the coil this should be done every year.
The bin brain may be partially restricted causing ice to melt faster.
1. clean out the drain.
The air flow to the condenser may be obstructed.
check to make sure there is nothing covering up the grill or coil.

If the machines ice storage capacity is 26 lb per a day then that is all it will make in a 24 hr day Now this depends on water temp entering the machine, the ambient temperature around the machine and the condenser coil and fan is not dirty. Now the machine is capable of making 33 lb of ice in a 24 hour day but the storage bin capacity is only 26 lb if you don't remove any ice it will make only around 26 lb and shut off until it melts and causes the ice maker head to start.

Why does water not shut off after making ice


Is the bin drain line and dump drain line tied together. If so then it is melting ice from the bin. now when ice machine starts up it will dump the old water in sump tray so it will be fresh water during new freeze cycle.

DCE33 Ice Machine


I believe it was the inlet water valve that needed to be replaced, but I got so fed up with the noise and repairs on this machine that I purchased a Whirlpool ice maker. So far, it's been great. It is much more quiet and produces 50 lbs of ice in 12 hours and shuts off until some of it melts. It only produces more ice about four times a day as it melts.
