I have two older bunn pour o matic units and both leak water. When I disassembled them I found that both have baked the plastic pour basin to the point of decay. It would be a simple fix if I could find a replacement pour basin. thanks fo any help. KIP

Re: leaking pour basin
Your only hope of getting a new tray for these would be if your local Bunn repair shop has some hanging around that broke down for another reason. This is a very common problem with those models. You can find a list of Bunn repair depots at www.bunn.com Good luck!

if the hole is near the top it is an overflow hole- so you can not put in to much water. unplug coffeemaker ,and take to sink- turn over and drain completely. set it back up and try again filling coffee put to just the top cup line and no more..
Either your fill tank is clogged, or your washer seal is cracked. You will need to remove the top of your Bunn to access this area. In the resevoir you will see a large nut with a drain hole. First try clearing the hole with a tooth pick and pour water in the basin. If it flows you have good drainage. Now, with the top still removed, pour water in the basin while checking for leaks. If a leak is present you should remove your drain nut and inspect the clear white looking washer on the underside. If it is cracked you can replace it with a gasket from Bunn. If you are tight on time and cash, a non rubber heat proof water hose gasket will suffice until yours arrives from Bunn. Replace and re-tighten the basin and drain nut (do not over tighten) .
Hi, is your unit a new VPR? it could have just a gasket that is not tight, or if you pour too fast it could overflow the fill reservoir. Either way you can go to www.bunnomatic.com and serch in either home, or commercial for the 800 number appropriate for you, thank you :)
The silicon seal inside the coffee maker tends to disintergrate. Bunn Inc. does not sell parts for the inside of the coffee makers, but a seal kit can be purchased through a small appliance repair center or repaired for a small cost. Kit is about $8.00 at most places.
Does it leak all of the time or just when you pour it in. There are a couple of solutions. There is a tank inside and a pan that leads the water to the tank. There is a gasket between the basin pan and the tank. It could be leaking from there but that is pretty rare. Generally what happens is that the basin may get chips or scale that builds up around the basin to tank access nut. The nut secures the basin to the tank with a flat,round silicone gasket between them to keep water from leaking. If scale impeads the free flow of water from the basin to the tank the water backs up and will give the impression of a brewer leak. I haven't worked on one in awhile but there are two screws that hold the pour over top to the brewer. The top can carefully be removed and a visual inspection is done (remember to unplug the brewer) to see if the access nut is clear. The lime could be in the nut or just below and inside the 3/8' hole that leads the water to the tank. Bunn makes a delimer spring that is used to clean out the sprayhead that I use to clean that nut. Speaking of sprayhead, if the leak happens during brewing and seems to come from the front take the brewbasket away and run about a half a pot of water through the brewer and see if it comes through the sprayhead's 5 holes. If it dribbles and doesn't fan out into the pot, or tracks along the roof of the brewer and drops down the side or back clean the sprayhead and try again. Also if it is the A10 or B8 I would run your delimer spring through it. If you don't have the spring you can get one at your local Bunnomatic representative's office. Or call Bunnomatic in Springfield, Illinois and they can send you one and instructions of how to use it. The picture of the bunn I am sending you is of a restaurant model but uses a pan just like the smaller bunns. This one is stainless but the principle is the same. The nut right by the 1/4" spicot is the water access nut, just like on yours. They will clog and leak, but I would check your sprayhead and the free flow of water from it before I do anything else. If it isn't either one of the solutions I have spoke about it could be a tank gasket or worse. Rick in Indy
I have an older BUNN B10 pour-o-matic that I thought was leaking from the bottom. Upon close inspection, I found that it was leaking from the worn out washers located on the top of the tank, allowing water to run down the sides of the stainless steel tank. There's a great fix offered on Fixya.com that suggests going to a hardware store and buying a Gardner Bender GHG-1575 rubber grommet with a 3/4" hole and install it into the large hole in the basin. Then place a metal washer on top of the grommet and snug it up with the threaded fitting. Many folks say it's a great fix. I went a different route. I called BUNN customer service and spoke to a very nice woman who understood my needs and sent out a free repair kit that contained a new fitting, washer, and seal. I received it in a few days and it's working great. Beats going out and buying parts for a work around repair. BTW, the repair kit is called "Universal Retail Seal Replacement Kit #37091.0000"
