Mr. Coffee Classic 12-Cup Coffeemaker - Cocoa (MRX35) Questions & Answers
Does not heat up or
Inside is a heating element, most likely burnt out. Because that type of machine is self contained unit it is time to throw it out, mr coffee machines are dime a dozen these days. Can pick up another at wall mart for about 30 bucks. Not worth even attempting to fix or take apart a self contained factory machine . Sorry there is no good news, simple fix on that type of machine, unless you have warranty on it.
This morning i plugged in the coffee maker and
Unplug it and start all over with the clock.. I'm not sure if this will work or not.. but it seems to work when my tv looses its sound.. some kind of chip inside.. well, if that dont work,, I will look in to that model and see whats going on..
Mr coffee beeps 3 times and thats all, no brew
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!
My mr. coffeemaker beeps 5 times and doesn't brew the coffee I just purchased this coffee pot last month aug 2014. what could be the problem
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.
