20 Most Recent Bunn NHB Coffee Maker Questions & Answers

Every time I plug in my bunn coffee maker, it trips the GFI. But when I plug it into another plug in my kitchen, it will work, but it seems like the water reserve is not right. It blows too much steam and the top starts lifting up from the pressure of the steam, then it starts leaking out the top left side. Then if I pour enough water to make 10 cups, it only makes 6 or 8. The coffee maker is only 3 years old, what should I do?

that needs to go back to bunn for a replacement tank, they will likely only charge you for return shipping

This is a home model pour over. Overfilling is the most common cause of leakage as there is no plumbed in water line. You should only pour in the amount indicated on the decanter. If it is overflowing, check if you have the right decanter as someone may have used an old pot from a larger brewer. Say there was a 12 cup pot around and now you have a 10 cup brewer. * carefully pour water to the inner fill line. You will probably see a ledge or spill off hole on the inside of the fill tank. Some units will spill out the back, others may spill back into the drip funnel. Note at what point you get near the spill level and note how much is left in the decanter. The amount left is your over flow. * If you want more accuracy then use a measuring cup and count how many cups are needed to fill the brewer. * Unplug any brewer that has water coming from the base. Dry up the area and drain the brewer. Dry off and let sit to completely dry out. Refill, note any leaks? If okay then plug in and brew as normal. * still having problems? Contact your vendor for service., Aloha, ukeboy57

CHECK THE WATER INLET SOLENOID. SOMETIMES DEBRIS( METAL/PLASTIC) ARE STUCK UNDER THE TINY ORIFICE KEEPING THE VALVE OPEN OR THE PLUNGER IS CORRODE/SPRING DAMAGED/WEEK. THAT WOULD EXPLAIN THE MALFUNCTION. RUDY.KY

Sounds like you have something clogged. First see if your unit is under warranty. If it is, then working on it will void your warranty and instead you should take to a certified warranty center. If it is out of warranty I suggest be sure that is un-plugged then try and clean as much of it as you can without immersing the electrical parts of it. If that doesn't work then it probably needs replacement parts. In 98% of small appliance cases it's usually more economical to simply buy a new one.

VPR is a pour over "Volume Displacement" brewer. Required to completely fill the inner tank and heat prior to using brewer. BEFORE plugging in unit, water must be poured into upper tray and with brew funnel and empty pot in place. Keep pouring water into top fill tray until water drips out of brew funnel. Plug in VPR and allow it 15-20 mins to heat up. leave the pot as there may be additional water dripping. Remove power if there is any water spilling out from other places like the top pan cover or bottom of machine. With the initial heating done, take a full pot of water and slowly pour into the top filling tray. HOT steaming water should come out of the brew funnel to fill the (empty) pot. Prep is done and the machine can be used to brew a pot after 10-15mins of reheat time. *** the machine you have needs to be checked for leaks in areas mentioned above. Water should only come out of brew funnel (if not present then the brew head or if that is missing then the brew pipe. All will need to be replaced prior to brewing.) Leaking under machine is an indication of leak(s) in pour tray,tank,tank cover, gasket, probe gasket. This machine like any used equipment should be checked out by qualified tech prior to use. Be aware that coffee vendors sometimes rent or loan brewers to customers.

Check the couplings of the rubber hoses to/from the heating element.

My warm indicator light is not working. Only used less than a month.

The leak is most likely between the water reservoir and the tank. Bunn uses a soft silicone seal for that connection that gets compressed over time and starts to leak water whenever you make a pot of coffee. It's planned obsolescence. Bunn won't sell you a new seal. So you have to improvise. But it's simple enough to do. Remove the top cover and the plastic water reservoir right below it. Don't tamper with the little valve that opens when you close the lid. Look for the seal. It could be stuck to the bottom of the reservoir, or sitting loosely on top of the metal tank. Make sure to preserve its top-to-bottom orientation (don't put it back in upside down). Apply a narrow bead of clear silicone into the grooved side of the seal. Press the seal gently onto the reservoir, then apply a thin layer to the smooth side. Re-install the reservoir and reassemble the unit.

To do that it is a good idea to put water for four cups and four coffee spoons of coffee. Kolbrun

Here is the manual for your unit: Bunn NHBX Use And Care Manual The reservoir is not removable.

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.

Most likely is that the seal between the water reservoir and the tank is leaking. Not uncommon. If you can find a replacement seal go for it, otherwise the old one can be made serviceable by coating both sides with a thin bead or layer of clear silicone. Allow to cure for 24 hours before powering the coffee maker back up.

Assuming your talking about the warming plate light, Google "bunn nhb warming switch" to search for replacements.

Check with Bunn and see if there has been a recall. I did in Canada and they sent me a new machine complete with some Tim Horton's coffee! http://www.bunn.com/Good Luck!

the water maybe wetted some electrical parts or ur tank heater faulty

Ours was leaking as well. Unplug the machine first. The entire top just snaps off in one piece. When you have this off, gently snap out the pivoting arm you are looking at that has a clear silicone cover over the drain to the tank. This needs to be cleaned along with the top resevour. Remove the brew basket (where you place the filter). Tip the unit upside down and drain the water. Unscrew the spray nozzle. There are two Phillips screws that need to come out. Remove them and then gently pry off the bottom section as well. It pivots from the back.The on/off switch will probably come out of it\'s mounting when you do this so take a good look at how it\'s placed so you can snap it back in when you go to reassemble the unit. The stainless steel band around the top of the unit will probably come off at some point during dis-assembly. This is just for looks so if you don\'t want to bother with the hassle of getting it back in place, don\'t worry about it.There is a silicone tube that attaches the bottom to the top. Pull this off for cleaning. Clean everything you see with white vinegar. Do a good job, soaking the tube, flapper, spray nozzle etc. If you saved the package that came with it when you bought the unit, there is a long, thin brush for cleaning the drain tube. If you don\'t have that anymore, pipe cleaners will work but be careful you don\'t poke a hole in the silicone tube. Leave the pivoting arm off the top of the fill tank and fill everything with white vinegar and let it soak. Dump it out and be amazed at all the crap that comes out. Do this a couple of times until nothing more comes out. Reassemble the entire unit making sure you get the silicone tube securely in place. This is a pain but take your time and do it right or it will leak. Fill everything with water and run it for a few cycles until it is flushed out. About once a month or so, dump out all the water and fill the tank with white vinegar, let it soak and then run a brew cycle with vinegar instead of water. Flush as above. The siphon, drain tube and spray nozzle get clogged with calcium and this is what causes the leaks.
