20 Most Recent Mr. Coffee GBX23 Questions & Answers

It might be a problem with your outlet, and not the coffee maker. Your kitchen outlets should be GFCI protected. There is supposed to be a sticker on all outlets that are protected by a Ground Fault Circuit Interrupter, but sometimes they are left off. Look for an outlet in the kitchen that has a rest button between the outlets. You can also take the coffee maker to a known working outlet, or bring something that you know works to the coffee maker outlet, to see if it is the outlet that is not working or if the coffee maker is still not working at a good outlet. If the outlet isn't working, try others in the kitchen to see if they are. If they are not, and you didn't locate a reset button on one of them, then check the breaker box for a tripped breaker. Coffee makers do have at least 2 safety switches inside them, but they are only to keep them from overheating and catching fire. If one of the switches did go bad it is possible that it might shut down the entire machine. If that is the case, then it's time for a new coffee maker, as the safety switches are not servicable. 120v AC GFCI outlets (220v AC outlets will have the same reset buttons)

First set the clock on the brewer with the unit plugged in. Press and hold the Hour and Minute buttons until the current time is set. Next press the Delay Brew button while using the Hour and Minute buttons to reach the time you want the coffee to begin brewing.

Set up the coffee maker with ground coffee or beans and sufficient water in the reservoir then follow the directions below.

For brewing with fresh ground beans, press and hold the Delay Brew button until it flashes then press Select once. The Grind and Brew light should come on and the Delay Brew light should become steady.

For ground coffee, press and hold the Delay Brew button and then press Select twice. The Brew Only light and the Delay Brew light should both be on and steady.

You need to clean it out every 3-4 days. I use a brush and pointed knife for the packed grounds. Mine works great now.

3 beeps means plugged water line. Take off the bottom of the coffee maker with a small phillips head screwdriver. Use pliers (I used needle nose type) to remove the wire clamps holding on the silicone water tubes to the hot plate. In my case, the water line from the reservoir to the plate was clogged with something I couldn't see until I blew on the hose and it popped out, could have been scale, grounds etc Clean with vinegar. Back in service!

if faulty and brand new return

TIME TO REPLACE IT

I see two problems that you've described. First, you have a bad empty-reservoir sensor. Mine went out on my first Mr. Coffee within the first month also. The purpose of the sensor is to trigger the beeping to simply let you know when the coffee is done. The coffeemaker would normally work fine otherwise. Second, you have a bad heating element. This is the core function of your coffeemaker and renders it useless for anything but a nice warming plate. I recommend replacing the coffeemaker. In the future, make sure you do not add water to the reservoir unless the coffeemaker has been turned of for at least five minutes. This will help prolong the life of the heating element. The heating element will naturally degrade over time. But, it can incur sudden damage when the reservoir is refilled with water too soon - while the element is still hot. Because of the simple design, if the coffeemaker is on, then both the warming plate's heating element and the reservoir's heating element are on. So, after a brewing cycle is complete, the reservoir's heating element stays on. Without any in the reservoir to keep it cool, the heating element superheats. So, if water is put in the reservoir while the coffeemaker is on or before the element has adequately cooled, the sudden burst of steam from the water contacting the element can be quite violent.
