New Mr. Coffee Espresso machine producing white gunk
I just got the Mr. Coffee Steam espresso machine. Running the first cycle with just water produced white flakes in the carafe. I ran it again with just water. Still a lot of particles in the carafe coming out of the machine. I have since run it about 20 more times, and it is still producing lots of white stuff. I have rinsed the resevoir repeatedly. I have used a descaling agent made for coffee makers, and nothing is helping-- every batch has some amount of flakes. What IS this? Is it fixable? Should i start over with another Mr. Coffee, or is this a common problem? I don't want white floaty bits in my coffee.
Re: New Mr. Coffee Espresso machine producing white gunk
I bought one this week and had the same problem. I used vinegar and rinsed thoroughly and yet the whit flakes remained. I did some research and found that high end espresso makers often have very fine screens that catch minerals and grounds and so on. This Mister Coffee espresso maker has only a metal basket with tiny holes so it's not really filtering anything. Moreover the metal is treated aluminum, so it scales naturally. Also, if your water is hard like mine that just makes things worse. I just tore off a piece of paper towel only big enough to line the bottom of the filter basket and not come up around the edges. Then I put a drop of water on the paper towel and pressed the paper towel against the filter basket so I could see the little holes through the paper towel. Then I rinsed the machine again and the white flakes were completely gone from the water and the paper towel had collected it instead. I did the same thing with a new piece of paper towel and I added coffee, I did not add the maximum amount of coffee and I did not tamp the coffee. The product was smooth and creamy as it came out of the machine very slowly. But it tasted great and it was strong and clean. Upon removing the basket I found hard dry grounds stuck to the basket and paper towel. I had to use a spoon and running water to dig all of it out. It's not as good as professional espresso makers, but it'll do for a quick shot. I hope that helps.

coffee-steam-espresso-and-cappuccino-maker--ecm160-np-/ECM160-NP.html ..... Thecoffee grounds don't come out wet like the other unit. ..... too much as the steam pressure only (no pump) isn't enough to force the water through the "cake".
Did your User Manual have a section that tells you how to clean out mineral deposits and hard water scale? Usually, this is done by filling the resevoir with white vinegar and then turning the machine ON for 30 seconds then OFF for 5 minutes. Keep repeating the ON-OFF cleaning cycle until all the vinegar is pumped into the carafe. If the machine needs further cleaning. Repeat the process until the scale and mineral deposits are dissolved. Finally, flush the machine with a full resevoir of clean water and run a normal BREW cycle. Should work like new.
It's probably clogged up with hard water deposits. Fill the water reservoir with plain white vinegar and put the espresso pot in place as usual, but do not load coffee! Run as usual for making espresso.You may have to run a couple of tanks, until the vinegar is pretty much colorless. Then run a couple of tanks of water to flush the vinegar. If your machine has a steam valve for frothing milk, put the steamer pot under it and open the valve as well. Over time, the steam valve can clog up with milk solids, called casein, which is actually a form of organic plastic.
The espresso portion may be clogged with hard water deposits, and the steamer tube with casein. Run a tank of plain white vinegar a couple of times then run a couple of tanks of plain water to flush the vinegar, Open the steam valve while the espresso portion is running and set the steamer pot under the steamer. Don't be surprised if a long white tube of hard white material slides out of the steamer valve. That's the casein, actually a form of organic plastic.
Clean the chamber below the white plastic valve, there is also a small discharge that leads from there into the drain tray clean that hole also. Second the thermostat that controls the steam may be damaged or the cpu board, the contact the controls the steam may be damaged, i have seen both of those happen on some units.
Put desired amount of water in resevoir (plus a little extra to be used to steam your milk for latte) and close up tightly.
Put espresso grind coffee in basket and tamp down with a tamper. If grounds are not packed, steam will seep through and will cause an erosion of sorts instead of just letting the steam hit the grounds.
Put the basket with handle group in recess rotating to the right as far as it will go.
Rotate the ON/OFF switch to the symbol for "Brew" until you get out the desired amount of espresso.
Then, take a caraf of milk and immerse it with the plastic black steam arm. Rotate switch to "STEAM" and froth milk. In the beginning, ensure that you have enough water for the espresso AND enough left to froth without having to shut off machine, refill with water, just to froth.
Be careful when you open the water resevoir cap after brewing because there is a vaccuum created and a burst of steam will shoot out the lid and may burn you.
The gasket above the grounds hopper eventually will deteriorate and more steam will escape than espresso is produced. There is no replacement parts for this machine since it was made in China according to a Mr. Coffee representative that I called this morning at 1-800-MR-COFFEE (800) 672-6333.
Good luck with your machine. Hope this helps! If you don't have a tamper for the grounds, I found one at Bed Bath and Beyond. It is stainless steel with 2 sizes. The smaller size works for this model.
so i guess our expresso you dont have that creamy topping that lack pressure descalcify not with vinegar remove caicium in chunks have a chance of blocking everything descalcifier solution melt the calcium 1part solution 1 part water fill the water with solution open the valve if some come out close it leave the solution in it for 15 minute repeat untill empty rinse very good cheers
