I have a bunn coffee maker and it started to leak really bad. Water all over the counter. I bought it in May of this year so I would think that it should last longer than that. The model is GRX-B and the date code is 155108. Can you tell me why it is leaking and what I can do about it> Thank you

Most likely the problem is in the water intake area. I have the same problem, I took my machine apart, removing the top revealed a plastic water chamber which leads to a connector that lets the water go into the heating chamber. The seal had become brittle, and the plastic water chamber also was degenerating where it met the heated water chamber. I replaced the rubber seal and that worked the first time, however, I think the plastic has now deteriorated to the point that I will need a new reservoir piece and a new seal. It's probably time to send in the unit for repair.
I think one repair for a 25-30 year old coffee maker sin't such a bad deal!

Is this a lot of water, or just a small amount.

As the unit sits over time and runs heating cycles, it may have some vapor come out of the vents. That will cool and collect around the unit.

try turning the unit off for the weekends. If you still have water around the unit, then it may have a leak in the tank.

there's probably a 'silicon rubber' hose that feeds hot water to the 'grounds basket'- it may be loose, or damaged. is it leaking water, or coffee?? we have a bunn 8-cup, which has a pre-heated water tank that brews a pot in about 3 min. energy waster, but when you need coffee, you need coffee!!! is your filter holder properly centered? is the carafe lid hole clean and un-obstructed?
if it's leaking water, and not too costly to replace- you may consider replacing it with a new one!
good luck!

I have the same problem and I took the coffee maker apart to find out why. The fitting for the hold in the black pastic that the water flows through to get into the stainless steel tank may not have a tight fitting with the plastic and that's where I had water leakage. I used some silicone sealant to fix the leak and the water stopped leaking!

sound like a gasket is bad. really nothing to do with brewing a half a pot. theirs not much can be done but replace the brewer. are you covered by warranty??

An overflow can occur when using certain kinds of coffee or the use of a water softener, bottled water, filtered water or reverse osmosis. If you will get the model and date code located on the bottom of the machine and contact customer service, a flow restrictor sprayhead can be sent out to you that will eliminate this problem.

Please get the model and the date code from the bottom of the machine and contact customer serivce. Depending on the date code, there might be a seal kit available or the machine can be replaced at no cost if 3 years old or less. If it is over 3 years old and the seal kit isn't available, the machine will be replaced at a reduced price.

According to the date code on this brewer, It should be still under the three year warranty period. Have her phone Bunn At 1-800-637-8606, and talk to the warranty department. If this brewer is under the 3 year warranty, they will let her know what to do with it. If not, there's just not a whole lot you can do with it, as the part you are describing is part of the main case.

there is an overfill tube in the rear that may be leaking.

I had the same with a Saeco it was caused by a leaky boiler, after replacement, it was fine...
