Watch my video on a pour over Bunn that had a heating problem, so I broke it down and cleaned it and explained where leaks come from in many situations on Bunnomatics...https://www.youtube.com/watch?v=tNVZkYPaZko

The following video shows a coffee maching that was limed up and not heating. This covers most brewers for the home and the principles of heating and running. I hope this helps. I use a volt/ohm meter and temp gauge to explain the working dynamics of the brewer. Good luck!https://www.youtube.com/watch?v=tNVZkYPaZko

The unit is not getting power. If the receptacle is protected by a GFI, then press the Reset button. Otherwise, check that the circuit breaker (or fuse) to that receptacle isn't tripped.

I had the same problem. On mine (and probably yours) the problem was the seal between the (upper) plastic water reservoir and the lower (metal) heating reservoir. No replacement seal is available.

I fixed mine by coating both sides of the old seal with aquarium grade clear silicone sealer - available at pet supply stores. Just a light (1/16") coating is all that's required. Carefully re-assemble and allow the sealer to cure for 24 hours.

I did that over a year ago, and it hasn't leaked a drop ever since.

The seal is not available. I fixed mine by coating each side of the old seal with aquarium grade clear silicone sealer - about 1/16" thick.
Re-assemble and allow it to cure for 24 hours.

This is generally an indication of a lime build-up in the water tubing. If you take off the sprayhead and insert the metal deliming tool into the water tubing all the way leaving out about 1-2 inches and twist it about 5-6 times, this should remove the lime deposits from the water tubing. Then flush out the machine with 2-3 decanters of water. If this doesn't fix the problem, then call customer service with the model and date code for further assistance.

try keeping pressure on it, and turn it around as you insert it. You are trying to go around a corner in the tubr, and sometimes it is hard to get it to go around the bend.

Dennis Karlen supplies repair parts for this problem. You can find the various kits on his website

http://www.jneuhaus.com/appliance/karlen.html

There are other suppliers who sell two silicon washers and a stainless steel washer in kits, but they tend to run considerably more.

The rubber washer would degrade quickly due to the heat. You may be able to get by with a new silicon washer. Check your local (not national chain but local francisee) hardware store.

Due to UL listings, warmer switches can't be sent out but your brewer can be sent in for repair. If you will call customer service at 800-352-2866 with the model and date, we will give you the cost and address.

The element can be replaced. I have rebuilt several thousand brewers of all types. My favorite brewer is Bunn. If it were me, depending on how old it was, I might just get a new one and chuck the old one because if you send it in to be fixed it will cost as much as a new one. If you do it yourself and you get the element, you should get the tank lid gaskets, and remove all the lime and by the time you get it done (especially if you live in some state like Indiana) and replace the heater element, getting wiring and parts together with no leaks from the fill basin or connecting parts, then removing the sprayhead every morning before brewing to be sure that small bits of lime scale aren't clogging the sprayhead. But that depends on the water used. You may find it will have not been worth your time. Here is the tip of tips...RO filtered water only. That's the ticket. You will get many years of service from your brewer. By the way, you can order the entire tank assembly and just drop it in...at least you could a few years ago. Have fun. Rick in Indiana

You my friend have an internal short and should not be using that coffee maker. Either send it in to be repaired or replace the maker.

There are many possible points that the leak can be.

You need to disassemble the machine and work it without the side panels of course with extra care since power electrical cables are exposed.

In this way with a very good visual check while the machine is in operation you can identify the leaking point and fix it.
