Bunn B10-B leaks

I used Foxhollowrun's solution and went to my local hardware store (Menard's). You can purchase 3/4" Hole Grommets typically found in the electrical department. The brand I purchased was Gardner Bender Model GHG-1575 3/4" Hole Grommets. Here is all that you need to do (very quick and easy):

1) Break away the brittle pieces from the original hole in the resevoir.

2) Remove the old rubber / plastic washers - I found I didn't need them. However, hang onto your metal washer that the drain screw goes through.

3) Slip the 3/4" grommet around the hole.

4) Place the original metal washer on top of the grommet.

5) Screw the drain screw back into the heater which will seal the grommet via pressure. Be sure not to over tighten it - I just snugged mine up.

6) Put everything back together, rinse several pots of water through it, check for leaks, and you should be good to go.

As Foxhollowrun indicated, you may need to tighten the drain screw a bit if you do have a leak. I lucked out - it worked the first time. I believe it cost me about $2 to fix. Also, I did not need any caulk. If you do use caulk, I was told you need to use food-grade caulk.

One last note - as Foxhollowrun indicated, the grommets are quick thick which is why I removed all of the old washers. The original metal washer is just thin enough to allow the drain screw to be reinstalled.

Thanks to Foxhollowrun for a great remedy!

My coffe maker leaks water all over the counter

If you haven't used a replacement carafe, then it is probably a clog in the drip orifice, at the bottom of the basket. Note: don't put hot water in your coffee maker as it will perk faster and cause an overflow. Only use cold water. If you have replaced the carafe then it is probably the wrong size.

Light in the rocker switch for warmer is blown.

It's an easy fix. If you're handy with a soldering iron, you can get a replacement switch (in your choice of colors - think about that!) at any electronics store, perhaps even Radio Shack. It's best to remove the old switch & bring it in to be matched.

If you're not so handy, I'd look around for one of the old, disappearing "mom&pop" electronics shops that you can still find in strip malls. These guys are happy for your business, and have decades of experience. They can do it for you.

If you bring it into a shop, you can save some money by tearing the coffee maker down first (and putting it back together yourself). Otherwise, you're paying them an hourly rate to do what you yourself can do.

Starts brewing to quick anddispenses before i can

Yes, I have a bunn also. Does the same thing. No way to fix problem, they don't have a shut off when pot is removed. What I did was bought a second pot I use to fill. Or you can use a water pitcher, just fill pot, pour into pitcher then fill machine. Only solution to help with problem, I do this and dont have coffee everywhere anymore.

Assuming that by "switch" you mean circuit breaker, this is indicative of an electrical short. The circuit breaker is tripping to protect from an overload hazard.
You need to rule out if the outlet itself is bad vs. faulty electronics in the BUNN itself. Here's how you can do that:
1. You may have too many appliances drawing power simultaneously from the same outlet or from other outlets sharing the same circuit. If there are other appliances connected, try removing them temporarily to see if the BUNN still trips the breaker. NOTE: If you are using an extension cord, timer or a surge protector, remove it and connect the BUNN directly to the wall socket. Moreover, do not operate appliances on outlets controlled by a dimmer or a switch.
2. If you are uncertain as to what the cause of the problem is, one option is to relocate the BUNN to another outlet on another circuit in your residence to see if it trips that too. If so, the electrical components in the coffeemaker itself are to blame and you should contact the manufacturer and/or an authorized service center ASAP.
3. If the BUNN was the only thing plugged into the outlet when it tripped, try plugging in something else that draws a similar amount of power/wattage to see if it also trips the circuit while running. If so, your outlet is the culprit and/or the circuit is being shared by too many other outlets in your home (particularly true of old buildings). Call an electrician and/or your property manager to inquire about a solution.
4. Type your BUNN model number and the word "recall" into a search engine. If there is a recall in effect that seems to involve the problem you have encountered, contact BUNN for your service and replacement options. If you determine that the outlet is working correctly and the circuit is not overloaded and you suspect the brewer is at fault but there is no recall notice, consider filing a report with BUNN and/or the Consumer Product Safety Commission. This is a serious safety hazard and needs to be reported to the appropriate parties.

My bunn thermofresh coffee pot will no longer keep

Is the coffee coming out hot enough? If you measure the coffee as it comes into the carafe, it should register at 175-185 degrees. If it doesn't, then it is a problem with the machine and needs to be replaced. If it is that temperature, then the carafe needs to be replaced. Please contact customer service with the model and date code located on the bottom of the machine. If the machine is 3 years or less it can be replaced at no cost. If over 3 years, it can be replaced at a reduced cost.
