20 Most Recent Bunn A10 Coffee Maker Questions & Answers


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.

Your pour over coffee brewer has a reservoir that holds more than a pot of water. First thing you need to do is turn off the machine. Then put the empty coffee pot on the burner. Then take another container and fill it with fresh cold water and pour it slowly into the coffee maker until it starts to come out into the coffee pot. Stop pouring in water.

Now turn the machine on and let it heat up. Now you can brew normally. The reservoir has to be filled before you turn it on or you will end up eventually burning up the heating element.

what do you mean by both sides of the pot? perhaps your basket hole is blocked or sprayhead is missing and water is going in faster than it can come out
