Bunn coffee maker

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!

You may not have enough water in the tank.
Follow these steps

1. With the coffee pot unplugged, fill your resevoir/tank until water begins pouring out of your sprayhead and brew basket.
2. Wait for the water to finish dripping then plug in your Bunn.
3. Let your Bunn warm up for at least 8 minutes.
4. Run a test cycle with clean water, remembering to use the water pitcher provided for this purpose, while leaving your empty pot on the burner beneath the brew basket.
5. If your cycle completed, and your coffee pot is filled to the desired level you are ready to make coffee.

Remember that these Bunn models have no water filter installed, so, the cleaner the water the better tasting the coffee.

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.

thats why it came with a plastic pitcher

Good luck!

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 when this occurs?

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.
