Most likely it is your tank heater, but look on the top of the tank heater, because sometimes the wire will burn off the top of the element

Bunn GRX-B won't heat and yes it is plugged in and vacation switch is on

You said "...turned vacation switch back on". In fact, it should be turned off for normal use.

If that's not the problem, and it's plugged into a GFCI outlet, press the RESET button (do not press the "test" button).

If still no joy, plug something else into that outlet to see if it works. If it doesn't, check the circuit breaker for that outllet.

My Bunn Thermofresh quit heating the water.

The Bun BTX-B has a pair of thermal fuses located on top of the water heater storage unit. If the pot is left without use for a week or so, the thermal fuses will blow if the top of the tank gets too hot (about 150 degrees Fahrenheit) due to the evaporation of water in the storage tank. The operating directions state clearly that if the unit is not going to be used for a few days to turn off the pot. These are there to prevent a fire in case someone does not follow the direction. This is the "MOST" common form of electrical failure in these pots.

To access the thermal fuse
1. Unplug the pot and drain pot by inverting the pot in an empty sink.
2. Remove the two Phillips screws located under the water fill flipper door.
3. Gently insert a small flat blade screw driver into the front top of the lid and remove top cover.
4. Remove the 4 screws inside the water routing tank and remove routing tank simply by lifting off.
5. The thermal fuse is mounted to the top of the tank under a clip and is easily slid out from under the clip. There is a brown wire (goes to power cord neutral) and a black wire (goes into tank disk access hole). Simply measure with a multimeter at lowest ohm setting, the meter should read continuity between the black and brown wires, if it reads an open circuit, the part is bad.

A replacement thermal fuze assembly kit is available off e-bay for about $10. You can buy individual thermal fuzes and replace one of the two that is bad for about $3, but I recommend the kit for most consumers as it comes with wire crimps already mounted and far easier for the average person to simply install. Repair takes about 5-10 minutes.

I have an Bunn model GRX-B datecode 304009 that leaks at the bottom, what can be done about it

Most likely cause 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.
