Why my bunn thermofresh coffee maker makes cold coffee

SOURCE: Bunn coffee maker leaks water

There are 3 seals in your unit that could cause your problem. there is a silicon seal right under the pour-in tray, and two on the top of the tank. one of those is for the thermostat, the other is for the sprayhead tube. any of these could leak, causing water to come out the bottom of the brewer. One other thing that can cause this is a scale buildup between the pour-in tray and the tank.

Yes Bunn will send you a repair kit free of charge. Just apply a bead of silicon below the rubber gasket before you tighten it down and it will solve the problem.

SOURCE: I need a wiring diagram for a Bunn BX coffee maker

I do apologize but these diagrams are not available. What is the problem with the machine? If you will get the model and code date from the bottom of the brewer and contact customer service, we can help resolve your issue. The machine carries a 3 year warranty and if it is 3 years old or less, it will be replaced at no cost. If it is older than 3 years old, then it will be replaced at a reduced price.

SOURCE: Bunn Coffee Maker Leaks out the bottom

I have an older BUNN B10 pour-o-matic that I thought was leaking from the bottom. Upon close inspection, I found that it was leaking from the worn out washers located on the top of the tank, allowing water to run down the sides of the stainless steel tank. There's a great fix offered on Fixya.com that suggests going to a hardware store and buying a Gardner Bender GHG-1575 rubber grommet with a 3/4" hole and install it into the large hole in the basin. Then place a metal washer on top of the grommet and snug it up with the threaded fitting. Many folks say it's a great fix. I went a different route. I called BUNN customer service and spoke to a very nice woman who understood my needs and sent out a free repair kit that contained a new fitting, washer, and seal. I received it in a few days and it's working great. Beats going out and buying parts for a work around repair. BTW, the repair kit is called "Universal Retail Seal Replacement Kit #37091.0000"

SOURCE: Bunn thermofresh makes very weak coffee

I don't know what the flow restrictor looks like, but I know what a spray head looks like.
My new Bunn BTX-B brewed weak coffee also. I was wasting coffee to get it stronger. I decided to inspect the spray head. What The hey! What Spray Head? The coffee maker didn't even have one. I guess the assembler forgot to put it on. Yet it made it thru quality control. No wonder it was making weak coffee, and I was wasting coffee to try get it stronger.
Is your making weak coffee? CHECK YOUR SPRAY HEAD. Make sure the coffee maker has one on it.
