CDA under counter fridge (no ice box) model number CW781/2, keeps filling with water at the bottom?

SOURCE: My subZero Model 245 Icemaker stopped making ice

Ice maker, I don't know where you can find the manual but I'll give you a few ideas of what to look for. First make sure that the inlet tube is not frozen over. Next, look at the center gear on the module and see if the clips in the center are not broken. If so you will have to replace the module. The ejector blades should be at the 2:00 position when home. If you get a jumper wire and jump T to H, this will by pass the bi-metal and run a cycle. The ice maker should fill at around the 12:00 position. Test points L & N will verify if you have 120v to the ice-maker. Test points L & H will test the resistance of the heater, 72 ohms. plus or minus 10%. Hope this gets you going, Catriver...post back.

SOURCE: clogged fridge drain tube

The drain is behind the back panel in the freezer at the bottom. Sounds like it is frozen over which is pretty common. Will need to remove panel and thaw out drain by running hot water down. You can use a putty knife to break up ice first. Make sure you get all ice around the drain above and below the thin aluminum tray at the bottom. After the drain is free don't be alarmed if you get some water on the floor because the drain pan may not hold all of the water you ran down the drain. Not anything you can do to prevent this on this model.

It sounds like the problem is what ever dispenses the water. If it is a mechanically controlled valve then there is something wrong with that system. If it is more high tech, then it could be the circuit board if that controlls the mechanism. The defrost plate shouldnt have much to do with the dispensing system.

Thanks to all who spent money or shared their experience to have somebody do this repair, and I really mean it.
I have a Whirlpool TopLoad Fridge (not a side by side).
Things you'll need
30 minutes
Small socket for cardboard panel on lower back and panel inside freezer
Bicycle Pump
4 Towels
Hair Dryer

1. Take everything out of freezer
2. Turn dials off in fridge for both compartments
3. Pull fridge out so you can get behind it and unplug it
4. Be vigilant of ice maker line if installed
5. Pull cardboard panel off on back
On the left side you should see the back of the skinny drip pan and a small line. That line goes from the freezer and is most likely clogged.
6. Blow dry the back of the freezer enough so the ice is thawed at the bottom of the back panel.
7. Remove the two screws on the back panel. You may just be able to pull it toward you enough to get behind it. You'll see the coils and fan, and underneath these you may see some ice sheets and there should be a hole. That is the drain line that is clogged. I heated up some water and poured it over the drain to thaw the line. You may want to remove the crisper drawers and put some towels down there to catch the overflow. Once the ice is thawed enough at the drain. Go to the back of the fridge and place the end of the bicycle pump at the bottom of the drain hose. Apply pressure to get a good seal but keep pumping. You may have to go back and forth between pumping and thawing, but you'll know it is clear when you hear air going into the freezer and then the wonderful moment when water drips into the drip pan as advertised!

Keep those fridges less full so that the door stays sealed and keep the seal clean and also keep your doors from having too much stuff so the weight of the door doesn't pull away.

Okay, put it back together, turn everything on and be careful of your cord and lines when pushing the fridge back. Thank the Lord ours has wheels and man,was it cruddy underneath. Vacuum those coils underneath the fridge too for proper air circulation.

Blessings to you!

first thing I would suggest is to flush the drain line. defrost any ice in the drain and then flush warm water thru the line until it flows freelyif  your having a hard time getting the line flushed out you may try using a large syringe or turrkey baster filled with warm water to forcfully flush water thru the line. this will most likely fix the problem.
you didnt mention if food was freezing in the refrig as well as the drain but there may be an off chance that the temperature control could be bad. since this is a manual defrost unit it depends on above freezing temps to help keep frost off of the cooling coil. if the temp control goes bad it will allow sub-freezing temps and possible drain freeze ups. so if the drain continues to freeze you will need to replace the temperature control.
if it comes to that, the control actually has a part number on it since maytag cant find your model number.
message me back if you have any further questions. thx peyton
