Leaks water After filling with water the water leaks out on to countertop. Almost a cup leaks. Is this a problem with this model?

This is a home model pour over. Overfilling is the most common cause of leakage as there is no plumbed in water line. You should only pour in the amount indicated on the decanter. If it is overflowing, check if you have the right decanter as someone may have used an old pot from a larger brewer. Say there was a 12 cup pot around and now you have a 10 cup brewer.
* carefully pour water to the inner fill line. You will probably see a ledge or spill off hole on the inside of the fill tank. Some units will spill out the back, others may spill back into the drip funnel. Note at what point you get near the spill level and note how much is left in the decanter. The amount left is your over flow.
* If you want more accuracy then use a measuring cup and count how many cups are needed to fill the brewer.
* Unplug any brewer that has water coming from the base. Dry up the area and drain the brewer. Dry off and let sit to completely dry out. Refill, note any leaks? If okay then plug in and brew as normal.
* still having problems? Contact your vendor for service.,

The A10 has a semi-sealed tank that keeps +1 pot of water heated and ready to brew. Pouring in a full pot of cold water will fill the top tray and allow a slow trickle of cold water into the top which forces hot water to over flow into the brew basket. This continues until all the cold water drains into the heater tank. So the brew is matched volume per volume. UNLESS the tank was empty or not filled prior to brewing. Follow the brewing instructions from Bunn (on line for *FREE* download at Bunn.com)
* If it leaks (from the bottom) only when you pour in water. Then your pouring it too fast and over flowing the fill tray. slowdown, watch the level in the tray. do not fill past the lid.
* If it leaks just sitting (not brewing) then there is a hole in the tank. Call for service.
* If it leaks after filling the tray half way. then the top of the tank has a leak, loose, cracked, or missing gasket. There is quite a few gaskets on the lid. Call for service.
* Final; Leaks are always bad around electrical equip. Best to unplug and call for service to be safe.

PS. Check your using the correct size decanter for this brewer. If it's a 10 cup brewer then make sure all the decanters in the office is also 10 cup. Pouring a 12 cup pot into brewer will have 12 cups of coffee come out (over flowing the 10 cup pot.) Note that not all decanters are made the same size. Other brands may be different. Test by filling a pot with water (from faucet) then pouring directly into pot in question. It should match and not under fill nor over fill.

Hi,
Below are solutions for a leaking coffee maker and how to decalcify the machine?
Tools and Materials needed to fix this problem are as:
* White Vinegar * Fresh Water * Volt-ohm Meter * Screwdriver
Step 1 - Clean
If your coffee maker seems to be clogged, try cleaning it with a mixture of white vinegar and water. Assuming that your coffee maker has a 12 cup capacity you will want to use 11 cups of vinegar and 1 cup of water. Fill the coffee pot to the 11 cup mark with vinegar and then fill it to the 12 cup mark with water.
Pour this mixture into the reservoir and turn on the coffee maker, allowing it to run through a brewing cycle as if you were making a pot of coffee. By doing this you will dissolve any build up in your coffee maker. If the coffee maker is leaking because the pump is clogged, then this might clear the clog and stop the leaking. If it has been a while since you last cleaned your coffee maker, you may need to run the vinegar through more than one cleaning cycle to dissolve all of the buildup.
Step 2 - Pump Valve
Unplug the coffee maker and examine the pump valve. If the pump valve is broken or has a clog, then the water will not be able to rise up and flow through the fill tube. When the coffee maker is turned on, the water needs to go someplace. If it cannot flow through the fill tube, then it may leak onto the countertop. If the pump in your coffee maker is sealed, you will need to replace the whole pump. If the pump is not sealed you should check it to ensure it is not clogged with coffee grounds or mineral deposits.
Step 3 - Brew Switch
Examine the brewing switch to ensure that is working. To get to the brewing switch, remove the base plate. Next, you will need to test the switch with your volt-ohm meter. Touch the tester to the RX1 scale. If it reads 0 ohms then you will know that the switch works fine. If it gives you a number other than 0 then it is time to replace the switch.
Step 4 - Tube Connectors
If the coffee maker is leaking or sputtering then you should take a look at the tube connectors. Many times, a leaky coffee maker is caused by faulty tube connectors. If you find the leak is in an elbow, clean the surfaces before you replace it. If the tube connector leaks, replace both the tube and the elbow so that you can be sure the pieces will both fit together properly.
To decalcify, you will be needing a : decalcifying cleaner and A container large enough to hold the same quantity of liquid as your water reservoir
1) Remove the machine's water reservoir. 2) Empty all liquid from the reservoir. 3) Fill the reservoir with warm water. 4) Add one packet of the recommended cleaner to the full reservoir and stir until the cleaner is dissolved. 5) Return the water reservoir to the machine. 6) Turn the machine on. 7) Set the large container underneath the steam wand. 8) Set up your machine so that hot water -NOT steam-will be emitted from the steam wand when the steam valve is opened. 9) Open the steam valve according to the manufacturer's instructions. 10) After all of the decalcifying solution has drained into the large container (within a few minutes this will occur), remove it and discard the liquid that has been collected. 11) Rinse the water reservoir thoroughly and then fill it with the type of water you usually use for brewing. 12) Return the water reservoir to its normal position. 13) Using only water repeat steps 7 through 9 until the water reservoir is empty again.
I hope the above helps....
Good luck.

Sounds like the fill tube at the ice maker is either out of alignment or has a crack in it.

The water supply line from the water inlet valve enters the rear of the freezer and releases the water into a large diameter fill tube. The fill tubes hangs above the fill cup which funnels the water into the ice mold. If the fill tube and fill cup are improperly aligned, water may spill out instead of going into the mold.

A leak is usually caused by a bad seal/gasket. If you will call customer service at 800-352-2866 with the model and date code we will be happy to assist you with this.

I had the same problem.. I took the clear rubber grommet piece off and added an additonal o ring I had left over from a pur water filter kit and it stops the water from leaking. What does annoy me is that it only pushes water cleanly through for about 30 sec then it drips very slowly for the remaining brew to fill two full shots (I like mine big).

Hi
You boiler is leaking and needs to be replaced. Check partsguru.com or ebay for replacements.

It would be hard to say exactly where the leak is coming from. However I would recommend to remove the back panel and check your fill tube to make sure water isnt dripping from there. If it is then replace the fill tube from valve to water cup in the icemaker. I believe the part would be 404 then the model of your unit
