Water pours out of the back - Mr. Coffee 072179228578 12 Cup Coffee Maker

it happens whenever the fridge goes on defrost. The problem is that the drain hole in the freezer is clogged. so whenever its in defrost, there is no where for the water to go so it flows into refrigerated compartment. you have to remove everything from freezer and remove the back panel. the drain hole is right below the evaporator. use a screw driver to break up the ice, you can use a coat hanger in the drain hole to clear the clog. pouring boiling hot water in the drain hole will help. listen for the water running into the drain pan, once you hear the water running down, you know its safe to put the freezer back together.

i have a water problem but mine is .. when i turn the machine on it just starts pouring water out and does not stop.. and the machine still says not ready all the time the water is pouring out.. anybody know how to fix this ??

If the problem is in the fridge 1: it could be moisture being drawn from unwrapped vegetables. 2: if you have a "wet wall" fridge check no food wrapping is touching the wet wall.

Open the temp gauge sensor (located in the back , top of the engine) and please make sure to open the lock and not to lose it as you will need it to tighten the sensor in its place. Open the water bottle and pour water in it and let the water come out from the back (the sensor) , you will see air bubbles coming out with the water , but keep on pouring water till you see no bubbles what so ever. put sensor back in its place while water bottle is full and while water is still coming out from the back to make sure that no air escapes inside with the water.You might need another person to help you pouring water while you are in the back.

you have to clean all the water corrosion off with rubbing alcohol and a toothbrush, then any blown or water damaged parts need to be replaced, you probably need a tv repairman.

you have a drain hose from the top back of the freezer down to the condensate pan on the bottom of the refrigerator near the floor
this hose is blocked causing ice to build up behind the rear inner wall.
remove the back of the freezer wall and using a funnel pour hot water in to the hose to clear the condensate hose also remove all the ice behind the wall; remove the back cardboard to see the water come through the hose into the condensate tray when you pour the water it should pour right through if it's clear

If it overfills and drips, look for an adjustment behind the plastic endcover with a +/- on it. - is less water.

If it continuously drips, replace the water inlet valve on the back where the house water supply comes in.

I had the same issue, poured in 8 and out came 6. Here's what I did to clean and fix.
1) Unplug the NHB
2) Remove accessories like the pot and basket
3) Bring NHB over to the sink
4) Snap off the entire top cover (not the swing lid) by starting at the front and lifting upward (the top cover is about 1/4" thick). The back of the top cover will pivot a bit and then pop off exposing the pour reservoir. Remove the flow stopper inside the pour reservoir by lifting it straight up.
5) Place the top cover and flow stopper aside.
6) Remove the brew diffuser (located underneath the top where the brew basket goes. Twist counterclockwise gently but forcefully enough to snap it past the lock tabs which hold it in place. You'll know that it you've done this correctly when it just falls out.
7) Still over the sink, tip the NHB in a fashion where the back side is facing upward and the brew side is facing down into the sink. You'll be holding the NHB horizontally by the top and bottom of the unit. This will allow any water in the tank to pour out the brew spout. Begin to tip the unit as if tipping upside down as this will allow any remaining water to drain out. If this does not work the brew spout hose may be clogged and you can just tip the unit entirely upside down to empty it from the fill hole in the pour reservoir.
8) Return the NHB to the upright position in the sink.
9) Using a scotch brite sponge and some baking soda, clean the inside of the pour reservoir and rinse.
10) Using the tool Bunn provided, clean out the brew spout hose which is located under the brew hat. This is the little hole where the water comes out. If you don't have the tool Bunn provided you could use something like a plastic tie-wrap. Don't use anything metal as the hose you're cleaning is made of plastic tube and could become punctured. Clean this hose for just a minute or two to ensure that there are no significant obstructions.
11) With the NHB upright in the sink, pour a slow stream of hot water from the faucet, about two cups, directly into the fill hole located in the pour reservoir.
12) Tip the unit horizontally, as in step 7, and place the tip of your finger over the pour reservoir fill hole covering it completely.
13) Shake the unit back and forth horizontally so the water in the tank splashes around and frees anything which may be built up in the tank. Some water may splash out of the brew spout hose.
14) Tip the unit as in step 7 to drain the tank water out.
15) Fill a 16 ounce glass with hot water and 2tbsp baking soda, mix and pour into the pour reservoir fill hole.
16) Repeat steps 13 and 14 once.
17) Repeat steps 11 through 14 three times.
18) Clean the pour reservoir cover, swing lid and flow stopper.
19) Put the flow stopper back in place.
20) Attach the top cover.
21) Clean the exterior of the NHB.
22) With the boil and warmer switches off, plug the NHB into the electrical outlet.
23) Turn the boil and warmer plate switches on.
24) Fill the NHB with one pot of cold water and close the swing lid. Wait one minute.
25) Fill the NHB with another pot of cold water. Place the pot on the warmer plate and close the swing lid. If water does not yet come out, fill with one more pot of water.
26) Allow water to drain from brew spout until it stops draining.
27) Empty pot.
28) Fill pot to 10 cup line and pour into the NHB. You should find that the NHB now delivers 10 cups back to the pot. Empty the pot.
29) Clean brew spout diffuser and replace back in the brew hat.
30) Clean the pot, pot lid and brew basket.
31) Wait ten minutes for the water in the tank to boil.
32) Brew your coffee as you normally would.

The only issue I experienced during this process was with the warmer plate switch. It appeared that the light in the switch blew although the warmer plate still warmed normally. Shortly after the water in the tank started boiling the warmer switch light started operating again.
