Reservoir heats but won't dispense

I have a commercial 3 burner Bunn with automatic water feed. You can hear the water heating in the reservoir but nothing comes through down into the pots. What could the problem be?

Make sure the tank is full. it'll take 2 1/2 brews to fill the tank. keep brewing until the water comes out. and yes, clean out the sprayhead holes and the drain in the fill tray in the top.

If you are pouring water in the manual brew basin, then check the sprayhead holes, then the spray tube, those could be blocked. If using the auto brew, check the solenoid and or brew switch.

If Bunn unit has been stored for a while, how do i clean it and get it ready to use?


Hi, W/D here.
To get your Bunn working again, place a filter into the basket, fill the reservoir, and allow it to begin dispensing into the carafe. This will take several pots of water to get it filled and overflowing (dispensing). Plug it in, and let the reservoir heat up. It's not necessary at this point to have the heating plate turned on, but you can do so if desired to check that it is working, then turn it back off. Once you hear the reservoir heating up, pour in 8 ounces of white vinegar, and let the machine dispense into the carafe. Place an additional 8 ounces of white vinegar into the carafe, and pour back into the reservoir. Let the water heat up again, and let the vinegar solution sit in the reservoir for about 30 minutes. Top off the carafe with cool water and allow the carafe to cool with the warming plate turned off. After the 30 minutes, pour the contents of the carafe back into the reservoir, and it will dispense again. The water in the reservoir will heat up again. Check the coffee filter for residue. If you see a lot of grainy material, change the filter, and repeat the cycle until the filter comes out clean. Save your old filters as you go. Lay them out in order on paper towels, and you'll be able to mark your progress. When the filters clear up, discontinue recycling the vinegar solution and, instead, fill the reservoir with fresh water. The sediment has by now been freed up (de-scaled) and will continue to come off in smaller and smaller quantities. Each time you place fresh water in the machine, the dispensed liquid will smell less and less like vinegar. When no vinegar odor can be detected, you are finished.
Best regards, --W/D--

It only makes 1/2 pot when I pour the water in after sitting over night some times it takes 2 pot of water or more to make a full pot


I recommend slowly pouring in about a half a pot of cold water without coffee in the filter basket 5 or so minutes before you brew in the morning. There are 2 good reasons to do this-
1. Overnight you are having some evaporation due to the fact that your Bunn brewer has a reservoir that keeps a couple of pots worth of water at brewing temperature... a better temp than most "home" model brewers. This will top off the reservoir and you will not "short pot" except for the amount that the grounds themselves hold back.
2. Also overnight, due to the fact that the water is kept hot, the oxygen can dissipate from the water in the tank. Topping off with fresh water will mean a fresher first pot.
The Bunn brewers have a low wattage/keep warm heater so the actual heating element isn't doing all of the work over those long periods... it only kicks on when the temperature in the reservoir drops considerably (like after brewing). Be sure to let the brewer heat back up before brewing (you will hear it stop heating)
Hope this helps.

We have a commercial 3 burner Bunn automatic coffee maker that only puts out warm water and makes weak coffee


If you're sure that you've followed the operation procedures correctly, the the thermostat of the Micro wave needs to be adjusted by a qualified person/Technician. if the problem persist, then you need to change the Element/Heating coil of the M-wave.

My friend gave me a Bunn thermal home coffee maker and I don't know how to make it work and can't seem to find directions on line?


Depending on which maker and how old it is it may have a switch for the heating element. The BUNN brewers have a reservoir inside that needs to be topped off BEFORE energizing the heating element/plugging it in. This usually will require about 3 pots being poured through until water starts to flow from the filter basket. (Have a pot in place to catch the water) Then it is safe to plug in your machine. After it heats up (about 20 minutes) you can load your grounds and pour through a pot of COLD water and voila... coffee.
Also, due to the reservoir you will want to not shut off or unplug your brewer... then it will be ready to brew next time.

I have a bunn coffee maker that when it brews the first pot is hot after that the next one is not. It is the coffee maker that has two warmers on top. i didnt know if would be the heating element or...


While this brewer does have a reservoir that keeps a couple of pots worth of water hot for brewing you can get a cooler second pot if you brew directly after. You should hear the brewer heating up after brewing. Try waiting until it is back to temperature before re-brewing. If that heating takes more than a few (3-4) minutes then you probably have a problem with the heating element and the water is only being heated by the "keep warm" heater.

Bunn VPR Series Coffee Maker will NOT dispense the water into the coffee pot?


This machine has a reservoir that holds about 2.5 pots and keeps them at brewing temperature. Therefore you should pour in 3 pots (with a pot in place under the filter basket) until water flows from the basket. Then, and ONLY then, it is safe to plug in the brewer. If you plug in the brewer BEFORE filling the reservoir you will burn up the heating element and will have to have it replaced.
After the initial filling and heat up (about 20 minutes) you are ready to pour through a pot of COLD water through and brew.

Water in resovoir boils away. Do I need a thermostat?


Listen to the unit after you make a pot of coffee. You will hear it start heating the water and then after the water heats up you will hear the unit shut down. If it is not shutting down and is continuing to run then yes you need a new thermostat.
