I have mold or lime deposits where the water goes in on my bunn coffee pot what can i clean it.

Water discharge tube from heated tank is likely caked with mineral deposits. Bunn makes a de-liming tool for just such a problem.
Google "bunn deliming tool", or buy it on Amazon.
Bunn Deliming Cleaning Spring 01193 0000

Running white vinegar thru the line will never cause damage ......and actually should help remove mineral deposits clogging the line. If you want you can reuse the white vinegar and run it thru several times till it has completely removed mineral deposits. Once it is cleaned using distilled water will prevent build up.

the fill drain is plugged and the water is overflowing. open the top and, using a phillips head screwdriver, poke through the lime buildup in the trough drain until the water goes down more freely.

You should call your vendor for service.
*** the following is for information only ***
* Lime build up is caused by heated water standing and cooling off or drying out as it stands.
* Daily wipe down of equipment and removal of standing water puddles help minimize this build up.
* washing pots daily will remove coffee stains and prevent build up.
* Do not allow pots with coffee or water to sit overnite on warmer plate.
* Internal lime requires a qualified tech to disassemble equip to service.

First make sure you have enough water in the machine. It holds about 2 and a half pots of water in the holding tank. If the machine sits for a week without use but is still plugged in, sometimes the water will evaporate down to the point where pouring one pot of water in, will not fill the tank back up. If you still don't get a water flow, take the brew funnel out and reach up where the water normally comes out, There is a round water dispenser about 2 inches in diameter. Unscrew it by turning countercloclwise. It has a dozen or so holes where the water come out. Be sure these holes are not stopped up. There is a small pipe fitting where you took the water dispenser off. Bunn makes a long spring like thing that fits into this hole to remove built up lime deposits. If you don't have one you can use a flexable wire like braided copper wire about 18 inches long to push through the hole and slide it back and forth until it comes out clean. If you have hard water, like well water you may be getting a lot of calcium build up in the tank. Put about a quart of vinegar in the next coffee pot and let it sit an hour. Pour water through the machine until it stops smelling like vinegar. That should solve your problems.

We recommend cleaning your machine with white vinegar for 2 hours and then using the metal deliming tool under where the sprayhead is located. IThen flush it out with 8-10 decanters of water. If this doesn't fix your problem, please call customer service at 800-352-2866 with the model and date code.

The metal proble is use to clean out the water tubing. Remove your sprayhead and insert the metal rod up in the hole leaving out about 1-2 inches. Then simply twist and turn the rod about 5-6 times. This will remove any lime deposits. Then flush out with 2-3 decanters of water. You can obtain a new manual by calling customer service or going to the website-www.bunn.com going to @home, then products-click on your brewer-and then select use and care manual and you can print it out or view it online.

I always use CLR to clean my coffee maker. You don't need much more than 1/4 cup and mix with 8 cups of water and brew it like you would make a pot of coffee, then dump it out and run 2-3 more pots of just water, that should work fine. Also, run vinegar thru the machine once in awhile to help keep it clean

try cleaning with white vinegar(50/50 with water)may have calcium deposits supposed to clean once a month-let it soak overnight use coofee filter to catch deposits run numerous times then throughly rinse with water!!! :)

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.
