Bunn Coffee Maker Problem

It took me a few days to figure out the problem, but a previous houseguest that just left put coffee grounds into the part where you pour the water in. Please tell me there is a way to flush this out!!!! I am so angry because I LOVE THIS COFFEEMAKER! Help me please.

Re: Bunn Coffee Maker Problem

If you can unscrew the sprayhead. use a new baby syringe and squirt water in the pipe that goes down inside the tank [sprayhead] turn the coffeepot on its back so the tank drains into the sink and flush out the sprayhead pipe. you may be able to purchase a cleaning spring for bunn o matics from nelson appliance on the web.

BT10B Coffee Maker: When I use Dunkin Donuts coffee in my Bunn coffee ...

Dunkin Donuts is a finer ground coffee and the water comes through so quickly that it isn't absorbed quick enough so you don't get the full flavor and it causes an overflow. If you will call Bunn Customer Service, a new flow restrictor can be sent to you to resolve this problem.

Coffee grounds overflow

An overflow can occur when using certain brands of coffee that are finer ground or using a water softener, bottled water, reverse osmosis, or filtered water. If you will call Bunn Customer Service, you can get a flow restrictor sprayhead which will eliminate this issue.

Will not percolate. Water is poured, it heats up, no coffee brew

Bunn Home brewers don't perculate. They work the same way that commercial brewers do. Fillit with water, let it heat for about 20 minutes, then put your filter and coffee grounds in the funnel, pour a pot of water into the machine, put the pot on the warmer, and let the water run through. Then enjoy a nice hot cup of coffee.

Firstly I would run a descaling solution through the tank and then make a few pots of coffee without using any coffee grounds. This will flush the sytem through.

I haveBX-B . I had the pot set up for me to push the on button for Monday Morning, but the water ran throug and it was not on.So now I have cold coffee in the Decanter.

The Bunn coffee maker does not operate as most coffee makes do. You cannot leave the Bunn in the off position and then just flip the switch to on and pour the water in. You will always get cold coffee if you do this. It takes time for it to heat the water. The On/Off switch should be left in the On position all the time. This keeps the water hot in the tank, thus providing hot water when you need to make coffee. You then just pour the cold water in the top, shut the lid, and have a pot of coffee in 3 minutes. The On/Off switch is a vacation switch, and you use it only when you are not going to use the coffee maker for a couple of days. Older Bunn coffee makers did not even have an On/Off button. You simply unplugged them when going on vacation. So turn the switch to the On position and leave it there. The unit will then work as designed. Forget how other coffee makers work, this is a Bunn and it is the fastest coffee maker you can buy and must be left on all the time. that way the water stays hot and the unit will keep it that way.

WE have the Bunn VPR series. It's a pourover

Hello this coffee maker has a one and a half gallon internal tank, could be one of a few problems, first thing to check is the spray head, unscrew this you may need some channel locks to get it off and check it..use a tooth pick to clear the 6 holes with any lime that may have formed...also if you use a commercial coffee company for your coffee they should have supplied you with a spring to clean the spray head tube. After checking these 2 items the next thing to check is there enough water in the tank..when the vpr is left on and not used for a few days the water in the tank takes approx two and a half pots of water to fill up the internal tank...try pouring another pot of water in...also turn machine off and take the 2 screws out of the top and see if there is lime blocking the drain hole in the fill pan. Hope this helps...please feel free to comment again if you have any other questions...Good Luck!!! Mike

Water wont come out of my bunn coffee maker

The first pot of water you put in the coffee maker just fills the water tank which is then heated up , once it gets to temperature you then pour second pot of water this pushes the hot water out of the tank through the coffee grounds into the waiting pot. This way you can make coffee faster than a regular coffee maker.

Using fine grind coffee in my Bunn Coffee maker is causing overflow grounds into my decanter. My Bunn manual says that I can receive a "Flow restrictor sprayhead" free of charge. How do I go...

Phone Bunn Directly, and ask for their warranty department. In canada, you can call 1-800-263-2256. In other countries, go to for the phone number closest to you.
