I had the same problem and fixed it. I took the bottom off. There is two hoses there which one has a (valve)plastic thing with little ball in it. I took the hoses off and the valve out of the hoses. I then cleaned the hoses,valve and the pipe arround the burner. There was like hard white dirt in them. I put back on the hoses without the valve. Tried to make coffee and it worked but was noisy . I ran it like that for a few days and still worked but noisy. I then took hose off and put back in valve. Then tried it again. It still worked but now it is quiet. Clean parts,hoses,valve,and pipe near burner good. Worked for me. Good Luck on yours.

!!!!FIXED!!!!I know this an old question, but I finally fixed mine. Hopefully this will help someone. I have a PSTX Mr. Coffee (10 cup) maker. Allow me to provide some background first ...I started a clean cycle, following the instructions in the booklet exactly. I used 4 cups of white vinegar and pressed the clean button. Easy, right? The reservoir emptied about 2/3, the clean light began blinking and an audible (steady) alarm sounded. I waited for 2 hours for that audible alarm to stop, but it never did. Finally, I unplugged the coffee maker, plugged it back in and tried again. Same results. By this time, I figured I had run enough vinegar through it to properly de-calcify the unit, so I repeated the "clean" steps numerous times with just plain water. Same results. I realized that I could still brew coffee; only thing is, the darned clean light would keep coming on when I pressed brew. Surely, I did something wrong or there would be an answer on the web. I searched many answers, but none fixed my problem. So I decided to call Mr. Coffee (US: 800.672.6333 or Canada: 800.667.8623). I navigated through the menu and found the troubleshooting section for cleaning. The automated voice said, "Place 6 cups of cleaner solution or white vinegar in the reservoir...."Stop the presses! Did she just say 6 cups? The manual clearly states 4 cups. Also, that's what everyone else on the web is reporting.So I tried it, and I only used water (since the pot was still relatively clean) - 6 cups of water - pressed the clean button. This is what you SHOULD expect:1. Place 6 cups of cleaner solution or white vinegar in the reservoir2. Press the "clean" button.3. When approximately 2/3 of the solution has brewed through, it will [apparently] stop brewing - the "clean" light will begin blinking (but there should NOT be any sort of audible alarm) - let the maker sit; it's still working on the clean cycle.4. The final 1/3 of the solution will brew through and the cleaning light will shut off.This CONCLUDES the cleaning cycle.Of course, you should just perform a few "regular brew" cycles with just plain water to clear out the vinegar (or cleaner solution) odor.Bottom line: The manual screwed all of us! 6 cups, not 4!Try it - Hope it works for you as well as it did for me.John

there is an overfill tube in the rear that may be leaking.

The solid beep means the machine wants more cleaning solution. About 2 cups more. This worked for me. I found this answer in a very colorful blog post. http://pauljenkins.tv/blog/why-i-almost-killed-somebody-when-i-cleaned-my-coffee-maker/

Sounds likea serious PIECE. Try running it on the regular mode with vinegar, or you could even use hot water.

Your heating element is plugged. The element gets water but not enough to build up enough pressure to push the water up to the drip head, when that happens what it will do is steam a little, overheat and shut off. I pulled a wire through my element got a lot of **** out now it works like new.

Anyone know where you can get a thermal switch? I have one of these models and really like it.

I think there is a real problem with the whole cleaning system with the Mr. Coffee Pot. I have one and after making only a few pots of coffee, the light starts blinking. I have cleaned it over and over and still get the same alert. My son had the same problem you have with his, it wouldn't finish the cleaning cycle. He'd had it awhile and ended up tossing it because it was beyond the warranty and store told him too bad. I've had other Mr Coffee makers and like them, but they didn't have the irritating "clean" alert OR the obnoxious BEEPING to let you know it's done brewing. If I knew this was going to be an issue - I would never have bought it. Why do they have to screw around with a good thing - more buttons and thing cycles to cause problems.

Turn the power off after you clean and rinse it. Leave it off for a minute. Plug it back in and all's well.
