SOURCE: my bunn is too slow

Use the de-liming spring to clean the copper tube behind the spray head. Pour several pots of clear white vinegar through the unit to further remove lime and scale from the interior of your coffee maker. My Bunn is 24 years old, and the only replacement parts I've ever required are new carafes and the 4041 silicone washer repair kit.

SOURCE: mr coffee 072179228578 won't brew

There is a thermal fuse of poor quality in every one of these machines to protect against fire.
If you are unlucky, it fails early and at a safe temperature, if you aren't it may hold forever.

Two years ago, I had three coffeemakers fail in two days; I got a refund instead of a fourth.

Because the parts are spot-welded together, these machines are essentially unrepairable.

If you want to peer inside, look for a cylindrical part about 5/8 " long with one pointed end; this is the thermal fuse.

DON'T consider bypassing it, I know of one counter that caught fire after the thermal switch that controls the heater got stuck.

Try running a cupfull of vinegar through it followed by a pot of plain water.This will remove any hard water deposits which may be blocking the tubes.

Why won't it brew when I press brew?

I don't know how old your coffee maker is but it has a thermal fuse for safety and after so long they will blow. This could be the reason it will not brew.

My mr coffee optimal brew just beeps constant when you press the brew now button

My hubbub and I "downgraded" to an "upgraded" Cuisinart to Mr. Coffee Optimal Brew 12 cup carafe, mainly d/t the carafe keeping the coffee hot with no burn taste and the stylish st. steel carafe. We've had 2 cuisinart's and both gave us leaking issues after 3 years of hard use (2 pots daily). The cuisinart leaked and also had the burned coffee taste, We unpacked the Mr. Coffee, cleaned all parts, after several attempts, finally stopped beeping and ran the first clean cycle. We are past ready for a great cup of joe...NO.pot ready, grounds in, attempt to turn it on and...that beeping almost got and may still get this apparatus taken back, traded, gone....but after reading my book that never says a word about beeping, I googled and saw MDLS1 replied and while I thought it was crazy I was not giving up without pulling out crazy, and it worked. After a solid hour, I found an answer... You can't just tap it here and there, I took resevoir off, banged it good, forceful but not to hurt my hand, took the basket out and banged the top and clapped around all sides, filled her up, turned it on and walla.made a perfect 10 cup = about 5 "normal" cups of joe, and it was good...pot made in 8-9 minutes, stayed hot over an hour when it was finished. Tonight, I have a hot cup, hubbub got his,and we are happy campers...however, one more beep and it's gone.

Repair mr. Coffee pump

Rare for a Mr. Coffee, but it sounds to me like your disc thermostat is stuck open, or a wire has dropped off. They usually stick closed and burn out the thermal cutouts.

Coffee pot turns off after brewing

This is the correct operation for this type of coffeemaker. It uses the thermal carafe to keep the coffee warm after brewing, and doesn't use power to operate a warming plate

All I need is the manual to my Mr.Coffee Pot how to set the timer to Mr. Coffee GBX23.

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.

Most Mr. Coffee product manuals are here: . The direct link to the GBX23 manual is .

I hope this helps.

I forgot to put water into my Mr. Coffee for a minute. When I realized it, I shut it off and poured in the water. When I restarted, it did not heat or brew.

All coffee makers use a thermal fuse which opens (interrupts) at a specific temperature, generally somewhere above boiling point and do not reset when cool.

They are designed to prevent fires if the thermal switch which cycles the heater fails and the heating element heats beyond its normal operating temperature.

These Chinese devices are poorly made and unpredictable in performance.

They are not user-replaceable since they are spot-welded on both ends; the only possibility is the replacement of the pre-assembled heating element/thermal switch/thermal fuse which will likely cost close or equal to the price of a new machine if at all available.

MR COFFEE FTX49. Brewing starts, then stops

Mine just started to do the exact same thing. So I decided to clean it using the "Clean" program and just water. I put the brewer through the cleaning program 3 times - each time it would brew water from 12 cups to 8 cups, I'd tap the brewer on the countertop, it would brew from 8 cups to 4 cups, tap it again, and it would brew the remaining cups. So, I called the Mr. Coffee help line (800-672-6333). The most-likely problem is that the hose is no longer attached in the water reservoir. The help line suggested that I take it in to a service center. I live in Urbana, IL and the closest service center is in Oak Lawn, IL - 2 hours away from me!!
Here is my solution:
1) Buy another coffee brewer.
2) Smash your current Mr. Coffee brewer into a million pieces (this relieves stress) and go buy another coffee brewer (probably stay away from Mr. Coffee products).
Hope this helps.

Coffee not brewing

This machine depends on heat to move the water to the top. The heating element, or thermal fuse, or burned contacts are the usual suspects. The warmer under the coffee pot is not part of the coffee making process. It is repairable.

Coffee won't brew

It is probily the thermal switch between hot wire and element. Check to see if you are getting power through this switch.
