After I replaced the seal on the tank my Bunn is getting extremely hot when the tank is heating the water. It is as the water is trying to come to a boil. I ran vinegar through it to clean it after I did this is when I started having this problem

Re: Getting extremely hot
It sounds like the thermostat is not working properly. Please get the model and date code located on the bottom of the machine. Then contact customer service with this information. If your brewer is 3 years old or less, it will be replaced at no cost. If it is over 3 years old, then it will be replaced at a reduced cost.

VPR has a semi-sealed tank that keeps +1 pot of water heated and ready to brew. Pouring in a full pot of cold water will fill the top tray and allow a slow trickle of cold water into the top which forces hot water to over flow into the brew basket. This continues until all the cold water drains into the heater tank. So the brew is matched volume per volume. UNLESS the thank was empty or not filled prior to brewing. Follow the brewing instructions from Bunn (on line for *FREE* download at Bunn.com)
* If it leaks (from the bottom) only when you pour in water. Then your pouring it too fast and over flowing the fill tray. slowdown, watch the level in the tray. do not fill past the lid.
* If it leaks just sitting (not brewing) then there is a hole in the tank. Call for service.
* If it leaks after filling the tray half way. then the top of the tank has a leak, loose, cracked, or missing gasket. There is quite a few gaskets on the lid. Call for service.
* Final; Leaks are always bad around electrical equip. Best to unplug and call for service to be safe.
This is really a home style VPR brewer (but looks nicer)
if you listen to their video (link below) they mention it has a pre-heated tank of water already in the brewer. This means the brewer needs to be pre-filled with a full pot of water and pre-heated prior to using the brewer. Unplugging this unit won't be a problem UNLESS it was emptied of tank water and not refilled when powered up.
* The unit will try and heat up the tank of water but if empty then just air which overheats the unit then blows the thermal fuse. Call for service.
* The warmer is still working but it's not hot enough to brew frequently as the warmer may take up to an hour to get the tank hot enough to brew or it may not get hot at all if it's own thermal fuse blew too.
* Final; call for service to be safe.
my bunn has 2 switches one on the left side to keep it HOT and the front one when brewed to keep it hot . the side switch if off will not heat the water and will not let the front heater be turned on either which is lighted
The Bunn has a little stopper that closes the water drain port in the reservoir while the lid is open. You can see a little white plastic pin protruding up out of the grate with the lid open. When you close the lid, it pushes on that pin which causes the stopper to lift off the drain port, allowing the water in the reservoir to enter the heating tank.
If water is entering the coffee basket BEFORE the lid is closed, then something is wrong with that little stopper. It may have a chunk of debris on it preventing it from sealing, or it may be deteriorated, torn, disconnected, etc.
Only way to know is to remove the the screws in the grate and pull the top off exposing the reservoir, and the stopper assembly. The little plastic flapper disc should be seated in the reservoir drain port. It should be relatively flat (not wrinkled) and covering the drain port completely. Test it by pouring some water into the reservoir. If it drains out without you activating the stopper, then a repair is needed.
Move the lever up and down and check its operation. The arm must move freely and close when released. There should be no dirt or debris on the sealing surface of the flapper nor on the sealing surface of the drain port. Gently clean with vinegar as necessary. If the seal is damaged, then a replacement is required.
If you haven't used a replacement carafe, then it is probably a clog in the drip orifice, at the bottom of the basket. Note: don't put hot water in your coffee maker as it will perk faster and cause an overflow. Only use cold water. If you have replaced the carafe then it is probably the wrong size.
It sounds as though the thermal cutout has been put to the test and it didn't pass. I would advise you to try to get the company that the repairman works for to replace the entire machine, after all it is brand new and changing parts at this venue could void the warantee.
The thermostat or tank heater is not working properly. Please get the model and date code located on the bottom of the machine and contact customer service. If your machine is 3 years old or less, it will be replaced free of charge. If you machine is over 3 years old, it will be replaced at a reduced price.
You can check to see if the switch on the side of the tank is turned on and is working, but if the problem is with the tank heater itself, you can't get replacement parts for this model unless you can find a broken one at a garage sale or a Bunn service center.
