20 Most Recent Bunn Coffee Pots: Thermal Carafe Questions & Answers


The only thing that comes to mind is the sprayhead is missing. Check the coffee ground after a brew to see if the coffee is wet all over or if there is just a spot in the middle that is saturated. If all the coffee is wet then the grind might be too course. If only the middle is wet and the edges is dry then check the sprayhead.

I do apologize that you haven't received an answer. The thermal carafe can be replaced at no cost to you but simply calling customer service with the model and date code.

If might not be the thermal pot, it is possible it is the machine itself. If you have a candy or meat thermometer, place it in the pot as soon as the coffee has completed brewing. The temperature should be at 175-185 degrees. If it isn't, then the machine needs replaced. If the temperature is correct, then please call customer service with the model and date code to get the thermal carafe replaced. If the temp isn't correct, and it is 3 years old or less, the machine will be replaced for no cost. If it is over 3 years old, it can be replaced at a reduced price.

Im assuming you tried it more than once and the tank is full when you start? If your doing manual fill pour over the timer has nothing to do with that. If it's plumbed with a water line, before you start changing your timer for the brew cycle, first try the easy fix which is unscrew the spray head. it's the piece the water comes out to the basket. Take the cleaning spring tool and rotate it as you push it thru the tube you just unscrew the spray head from. As your pushing it thru it has two turns in it . Just rotate and push until you have gone thru the second one and then it's clear to the water tank. Unfortunately this doesn't always get it unplugged. Where the tube goes into the water tank there is silicone hub on the part that's in the tank and it can keep some of the lime buildup from being removed. You will have to take the top off and remove the tube to clean it if that happenes. Dont forget to unplug it first. The other common spot for a restriction is where the water leaves the pan your pouring into. You need to remove the pan to get the spray tube out anyway so look also at the big nut that holds the pan onto the tank.sometimes the hole will plug in the center .

test element for failure

Bunn Coffee... | Answered on Oct 06, 2019


Couple of ideas.

Your weak coffee could be due to the machine not getting hot enough, which is usually caused by calcium scale buildup on the heating element (the "burner").

Try descaling with a citric-acid based cleaner, such as Dezcal or Durgol.

The second is the coffee your using is a weak blend. Try changing to a different coffee and see if the strength is better.

This sounds like the light flickering rather than a faulty connection. You can check for a bad connection by tuning a nearby radio receiver to no station in the AM band. If there is a bad connection causing this you'll hear the sparking (in time with the flickering) on the radio.
Flickering is a common effect seen with neon indicator lights when they age and does not affect the switch function at all, so can be safely ignored.

The water inlet valve may be stuck open from mineral deposits. You can get rebuild kits for the older ones or just replace the valve?

If all passages are not plugged up it should flow through with or without heat in the tank.

It could be so much lime build up that the water going in is too much for the water to come out so it will leak out the top from the thermostat hole plug and or the water pan is flowing over the top cus no place else to go?

Underneath the warming plate is a element assembly that will have 1 or 2 thermal fuses and a temp sensor. If any of these have faulted that condition will arise.
I suspect that the temperature sensor is 'sticking' in the open position. If you remove the bottom cover (while unplugged of course) and lightly tap the sensor with your screwdriver it may remedy the issue for awhile but the initial cause of the problem will still exist. If the brewer is worth it you can replace the sensor otherwise it may just be cheaper to recycle it.
