Dripping My Bunn coffee maker drips immediately when the water is poured in and before I close the lid.

The Bunn has a little stopper that closes the water drain port in the reservoir while the lid is open. You can see a little white plastic pin protruding up out of the grate with the lid open. When you close the lid, it pushes on that pin which causes the stopper to lift off the drain port, allowing the water in the reservoir to enter the heating tank.

If water is entering the coffee basket BEFORE the lid is closed, then something is wrong with that little stopper. It may have a chunk of debris on it preventing it from sealing, or it may be deteriorated, torn, disconnected, etc.

Only way to know is to remove the the screws in the grate and pull the top off exposing the reservoir, and the stopper assembly. The little plastic flapper disc should be seated in the reservoir drain port. It should be relatively flat (not wrinkled) and covering the drain port completely. Test it by pouring some water into the reservoir. If it drains out without you activating the stopper, then a repair is needed.

Move the lever up and down and check its operation. The arm must move freely and close when released. There should be no dirt or debris on the sealing surface of the flapper nor on the sealing surface of the drain port. Gently clean with vinegar as necessary. If the seal is damaged, then a replacement is required.

This is common with bunn coffee makers, if you are not fast enough, coffee starts dripping. The only solution I found is to use a water pitcher, first fill coffee pot to cup mark you are using, then pour into pitcher, put pot back on machine, then pour in water. You can mark a line on picture, so you know where to fill to each time.

This can occur when the machine has a lime build-up. I would recommend cleaning and deliming the machine and if this doesn't fix the problem, call 800-352-2866 for further assistance.

Make sure all hinges & covers are correctly on!

I work for BUNN. Has your issue been resolved? The rocker arm is inside the pour in bowl (where you pour in the water for brewing). To get to it you have to take off the entire top lid (not just the spin lid above the pouring area). That can be removed by lifting it up and then you simply snap it back on when you are finished. Hope this helps.

You might try this first. Remove the entire top lid and remove the clear suction cup located near the back of the brewer. Clean this cup with white vinegar and also take your deliming tool and place it in the hole where the suction cup was and clean out. If this does not correct the problem, please call customer service with the model and code date. If your machine is 3 years old or less, we can replace it at no cost. If it is over 3 years old, we will replace it at a reduced price.

When setting up a new machine, it requires 2 full decanters of water to be poured into the machine. After you have done this, then you plug the machine in and turn on the vacation switch on the side of the machine. After 15 min, then you will pour in 4-10 cups of water and it will force out the hot water from the tank in the back and brew the coffee. If this doesn't correct the problem, then please call customer service with the model and date code.

The Bunn coffee machine has an internal tank used for holding approx three potfulls of water at just below brewing temperature. When you add water for a potful, the thermostat senses cold water and starts the brew heater. The water level inside the tank comes up and goes through the sprayhead. This "surge" of water, that you call drips is normal. The hot water stratifies to the top of the tank, just like an electric water tank in a house. The internal pot heater kicks in and boils the water already in the tank, raising the water level in the siphon pipe to the sprayhead until the reservoir under the add water opening is empty.

Is the burner hot while your pouring water in?

no, the water level in the tank goes up and out the siphon tube. you have about ten seconds before the machine starts to brew a pot.
