Bunn coffee maker reservoir makes a gurgling noise
Wehn I refill the reservoir of my Bunn coffee maker, it makes a loud, kind of loud boiling sound, almost popping..it is still working fine but I wonder if it is the heating element starting to go out. Or does something need cleaned? I think it is about 4-5 years old. It is a 10 cup home model.

Re: Bunn coffee maker reservoir makes a gurgling noise
THis sound is usually caused by the water being low in the tank. This can be because the machine is left on for long periods without being used. If this is not the case, then it would probably be your heating element getting small holes in it.

It sounds like the sensor that switches from brew to keep warm is faulty... so it keeps boiling after it's brewed.
My suggestion to you is to clean it it with vinegar. The following link shows how to clean a ten-cup model. Just use smaller amounts for the six-cup model.
Are you leaving the machine on all the time? If not, you need to turn it on and leave on for 15 minutes before brewing a pot of coffee. If you will get the model and date# from the bottom of the brewer and give us a call we will be happy to assist you with this.
This is usually caused by the thermostat allowed the machine to boil the water. We offer an out-of-warranty exchange to get a new machine. If you will call customer service at 800-352-2866, we will be happy to assist you in getting a new machine.
The switches are for the "warmers" only. The brewer has a reservoir the keeps water hot and ready for brewing. When it is not re-heating water (after brewing) it has a "keep warm" heater that is low voltage and keeps it ready to go.
It sounds like the thermostat might be allowing the water to boil and cause the grounds to be scorched and making your coffee bitter. It also could be caused by the machine needing to be cleaned and delimed. I would recommend you do this first-and if you don't have the use and care manual, you may call Customer Service to have one sent out or access one at www.bunn.com @ home, then products.
Usually this is the expansion of steam as the heating element quickly rises to the preset temperature. This process heats the water to the correct temperature and causes the water to flow upward from the water reservoir. Then out the brewing spout over the coffee grounds.
It will usually make strange noises at the end of this cycle too. The water is used up and remaining steam is vented. Sounds more like a burping and last minute gurgle really. :)
Are you rapid firing your coffee maker?Not designed to do that.. If the water heated that fast it would boil dry if you ever left it unattended and on. The reservoir is heated with the time it takes to drink a full pot taken into consideration for reheating.. If you are serving 20 cups with a 10 cup machine, Expect a delay, especially if you are refilling with cold tap water. Sorry.
