If u haven't cleaned it out using 3/4 vinegar to 1/4 water, some times this will happen. after running this thru ur coffee maker, (u won't believe the junk that comes out), then run full pots of water to rinse out (2x's). This should help it perform better.

Replace the water faucet. Contact the company the unit was sold or installed by. they should have the part in stock.

It could be few things. There is a in line fuse that goes to the heater it is usually black in col because of the heat but it connects to the heater and leads back and connects to a black wire, usually. Make sure it is unplugged. Take the top off and disconnect the fuse on both ends and use as volt meter to check for continuity from one end to another. If there is no continuity you can bypass the fuse with a just a straight wire with the male connectors on it. You can find a replacement here and also a picture of what you should look for http://www.google.com/imgres?imgurl=http://cf.mp-cdn.net/dd/26/7e07e7a94b56ff20da51483d5de1.jpg&imgrefurl=http://www.monstermarketplace.com/coffee-brewers-and-equipment/bunn-20211-0100-thermal-fuse-thermo-htr-c-fct&usg=__QFM1R-qQZJmi3bmnGq11Z2M1yoY=&h=122&w=625&sz=6&hl=en&start=6&zoom=1&itbs=1&tbnid=y4KMBBVcmaPKeM:&tbnh=27&tbnw=136&prev=/images%3Fq%3Dbunn%2Bo%2Bmatic%2Bthermal%2Bfuse%26hl%3Den%26gbv%3D2%26tbs%3Disch:1 .

The brew volume needs to be programmed, remove the 6 screws on the front panel and you will find the instructions to do this.

Run a pot of half water and half vinegar through the coffee pot and you may need to repeat this process a couple times to get all the calcium buildup cleaned out of the pot. Hope this helps.

Check the setting on the thermostat.

Check the big fitting on the back of the brewer, there is a micro filter in there, that might be blocked, if not then check the solenoid behind the front panel. Easiest way to make sure tank is full is to pour water in through the manual fill and let it flow out the sprayhead.

Remove the top panel, then remove the water basin check to make sure the hole leading into the tank from the basin is not blocked.

Check the thermostat on the top of the boiler and the inline fuse on the element to the ready light.

Hello, The coffee maker has 2 places where it is common to have a leak. Unplug the machine then take the lid off. Next using a coin remove the bolt holding the fill pan to the tank (it's the nut on the inlet to the tank) once this fill pan is out you will see the top of the tank. Here is the first spot it can leak around the tank lid gasket. You will normally see evidence of water leaking. The second place if you look at the top of the tank is the tube running from the tank to the basket, this has a gasket that commonly goes bad. Find which gasket is leaking and replace it. If you are buying your coffee from a local coffee company they will normally repair the machine for you even if you own the machine. if not you can either get the new gaskets by calling Bunn or from a company in California called holiday house. You could also try getting the part from a local coffee company but they will try to send a sales guy out with the part :) Hope this helps! If you have any other questions please feel free to comment. Mike

Check the other inline fuse on the element to the light, if you get resistance, then the problem is the adjustable thermostat.

We could have 2 things going, the easiest is to remove the spray head, and using the deliming spring clean out the brew tube.
The hard way is to check the water level, brew 2 pots to check level, if you get the exact amount in both pots, then wee will program the brewer. Depending the model you might have a timer knob behind panel or a circuit board.
If timer knob then turn to a longer time settings.
If a circuit board the settings and instruction are pasted on the front label.

Im assuming you tried it more than once and the tank is full when you start? If your doing manual fill pour over the timer has nothing to do with that. If it's plumbed with a water line, before you start changing your timer for the brew cycle, first try the easy fix which is unscrew the spray head. it's the piece the water comes out to the basket. Take the cleaning spring tool and rotate it as you push it thru the tube you just unscrew the spray head from. As your pushing it thru it has two turns in it . Just rotate and push until you have gone thru the second one and then it's clear to the water tank. Unfortunately this doesn't always get it unplugged. Where the tube goes into the water tank there is silicone hub on the part that's in the tank and it can keep some of the lime buildup from being removed. You will have to take the top off and remove the tube to clean it if that happenes. Dont forget to unplug it first. The other common spot for a restriction is where the water leaves the pan your pouring into. You need to remove the pan to get the spray tube out anyway so look also at the big nut that holds the pan onto the tank.sometimes the hole will plug in the center .
