Bunn automatic coffeemaker leaks water after making a pot

I recommend slowly pouring in about a half a pot of cold water without coffee in the filter basket 5 or so minutes before you brew in the morning. There are 2 good reasons to do this-
1. Overnight you are having some evaporation due to the fact that your Bunn brewer has a reservoir that keeps a couple of pots worth of water at brewing temperature... a better temp than most "home" model brewers. This will top off the reservoir and you will not "short pot" except for the amount that the grounds themselves hold back.
2. Also overnight, due to the fact that the water is kept hot, the oxygen can dissipate from the water in the tank. Topping off with fresh water will mean a fresher first pot.
The Bunn brewers have a low wattage/keep warm heater so the actual heating element isn't doing all of the work over those long periods... it only kicks on when the temperature in the reservoir drops considerably (like after brewing). Be sure to let the brewer heat back up before brewing (you will hear it stop heating)
Hope this helps.

The brewer probably has a bad seal or gasket. By the date code, your machine is 5 years old. If you call Bunn Customer Service they will be able to offer you an exchange of your old brewer for a new one at a reduced price.

the old fashioned way to clean a coffee maker is to run vinager through it then follow with a couple of pots of water that has a bit a baking soda in it.

You need to replace the thermostat and the hi limit switch punch up bunnomatic.com and get partsthis machine is good for many years

Sounds like a leaking water pipe from the water source, unless you have a over temp heater and this results in steam and dripping.

you can always clean a coffeemaker with vinegar, but always pour in cold, so you can do it twice or more, but dont re-use the stuff you just used, wait till it's cold or just use some other.after use clean by let water through 2 or 3 times, (also only cold water)

My Tim Hortons coffee pot leake water out the sides when I add water to make more coffee. What should I do ? I like the coffee maker it makes great coffee,

What's happening is that it isn't leaking, it's boiling over. You need to turn down the thermostat under the top lid. Also, before you brew coffee, add water to the tank and let it pour into an empty pot. Once it stops brewing, let it heat up for a few minutes then make your pot of coffee.

The easiest way to empty these brewers is to turn them upside down over the sink. Turn it on it's side, always keeping the fill hole down toward the sink, and keep on going until you have the unit completely upside down. If there is a push switch under the lid to stop water from going into the pot until the lid is closed, you will have to keep this pushed in until the unit is empty
