Question about Black & Decker SmartBrew DCM500 Coffee Maker

1 Answer

Plastic Chunks???? My coffee maker worked fine for a few months, then suddenly I noticed bits of something black showing up in my drinks. It seems to be flakes of black plastic, but I don't know where they are coming from or how to solve the problem. I tried cleaning out the hole where the water comes out. I got a few of the flakes out that way but it has not solved the problem. Anyone know what to do? This is really irritating me.

Re: Plastic Chunks????

There's a good chance that what you're seeing is a combination of limescale and residue from all the coffee that's been through the machine. Running the machine through with a proprietary descaler might well make a difference. A.

My coffee from my keurig is too hot

Coffee is mostly water, so can't pass over 100?C. All coffee makers work under the principle of boiling the water and pass the steam through the grinded coffee
If you wait some time, it cools off to a confortable temperature to drink.
Just guess you wanted to ask something else. In some coffee makers you should not use coffee grinded too fine or should not compact the coffee because it get's "explosive"

When I turn on the steam function a steady stream of water comes out fow a few seconds and then diminshes to a few drops when the pumps comes on every few seconds , but no steam comes out nozzle. I ha

This is similar to my Saeco. i only drink black coffee so the steam function is very rarely used. When i went to use it recently got same as your description. this then set a 'blocked' code on computer which meant NO COFFEE! EEEKKK.
I used an old soft drink bottle as a resevoir to operate the machine with covers off so i could see an issues. I started at the filter , blew that out with compressed air. then 1 at a time ...tank to filter, filter to pump, pump to heat exchanger, heat exchanger to spout (watch this one as it is steam!)
after a thorough strip and assemble i descaled and was good to go. now i make sure to use steam at least once a month.

Suddenly stopped working.

If you are talking that the while unit failed or just the coffee? If the light comes on and the coffee is not brewing than it is the heat plate fuse. You need tamper torx bits to open the unit and replace the fuse, radio shack sells them.

Water coming out very slow and no 'puff' at end all of a sudden this am

I had the same problem. The needle that punctures the top of the k-cup gets clogged with coffee grounds so we took a fine wire like a twist tie with the paper off and carefully slid it up into the needle to open it. It works great now! It is also a good practice to run vinegar through your maker every few months, those instructions are in the manual. :)

Maker clicks on, but doesn't perk or heat the plate.

Unlike older coffee makers, the new Mr. Coffee designs seem to have reliability issues in regard to their circuit boards/controllers. You are right in your thoughts. If the unit is under warranty, I would suggest returning it for a replacement. E-mail your concerns directly to the company.

BTW--there are no user serviceable items within your coffee maker.

If the hot plate is tilted then it should be able to be pushed back down until it is completely level. If not then it is damaged. Check to see that it is screwed in properly underneath.
