Help, i love my bunn coffee maker but lately its takes forever to brew a pot of coffee, i have taken the basker of and unscrewed the little thingy the hot water comes out of and cleaned it. but it still takes 20 mins or more to brew 10 cups. please help cause i can not afford a new coffee maker. if i have to buy anew one it will have to be a cheap mr. coffee or something. once you have used a bunn, no coffee taste as good.
Use the de-liming spring to clean the copper tube behind the spray head. Pour several pots of clear white vinegar through the unit to further remove lime and scale from the interior of your coffee maker. My Bunn is 24 years old, and the only replacement parts I've ever required are new carafes and the 4041 silicone washer repair kit.

Have you taken the sprayhead off (remove basket and look up)? This copper tube gets clogged with lime/calcium and needs to be cleaned. They have a delimer that usually comes with a new bunn, (12 inch coily spring) that needs to be ran up the tube that the sprayhead is connected to. If it is still slow after that, the the tank itself has a buildup inside.
While this brewer does have a reservoir that keeps a couple of pots worth of water hot for brewing you can get a cooler second pot if you brew directly after. You should hear the brewer heating up after brewing. Try waiting until it is back to temperature before re-brewing. If that heating takes more than a few (3-4) minutes then you probably have a problem with the heating element and the water is only being heated by the "keep warm" heater.
It sounds like the thermostat might be allowing the water to boil and cause the grounds to be scorched and making your coffee bitter. It also could be caused by the machine needing to be cleaned and delimed. I would recommend you do this first-and if you don't have the use and care manual, you may call Customer Service to have one sent out or access one at www.bunn.com @ home, then products.
Make a 1/2 pot 50/50 mixture of cold water and white vinegar then run it through the machine in normal brewing fashion. Place a clean filter in the brewing cup to catch the white deposits that are removed. Allow the mixture to cool, then repeat the process several times while using the same filter. Finally, run several pots of fresh water through to work out the taste of the vinegar. Repeat whenever the brewing time seems to be excessive.
get out the spring that came with it and ramrod the tube
un screw the shower head and clean that first the ram out the tube then reolace the head
this pot is not heat sensative when brewing coffee, like most of the other types
also pour in a quart of white vinegar, followed by 4 or 5 pots of water
I would ask if this machine has been moved lately- for cleaning or has anyone put anything new around the brewer? If someone has moved this brewer, they might have caused a kink in the line coming to the back of the brewer. this will restrict the water flow to the brewer. this will cause the brewer to brew only part pots of coffee.
I have had that problem with my bunn and I unscrewed the nozzle and it didnt help.My pot came with a wire so long u are totake that wire and stick it up in there and it cleans it out .If that does not work run cleaner threw it but i would not use vinegar.Thats the best i can do,it worked for me.
