On my machine, the vent from the heating element to the steamer control was clogged. I am a trained professional, do this at your own risk! I did the following because I tried everything else and I knew that the unit was clogged at the aperature from the hot water element tank. Try to unclog it another way before doing this!
1. Unplug from the wall outlet!!! (don't skip this or you might die!)
2. Remove accessories, water holder, bottom tray, etc.
3. Remove the rubber feet and unscrew all of the screws you can find. There are some hard to find screws but it is possible to remove them all with the right screwdrivers. I broke the last screw stud thing on mine because I couldn't find the right tool for that last screw. Once I got it apart, I figured out how to do it. I cant remember now though. Just break it if you want. There are plenty of other screws holding this thing together.
4. Remove the top.
5. Follow the smallest tube to the heating element (looks like a tiny hot water heater).
6. Unbolt the tube fitting at the heating element. You may loosen the other couplers, but dont completely unscrew them, and DO NOT TUG on the small plastic tube. Once you unscrew the brass fitting, take a flashlight and look in the hole that leads into the heating tank. If yours is like mine, it will be clogged with white goo. My goo was from hard water. Take a pipe cleaner and ram it through the goo. Try to get as much goo out as you can, but it is ok to get some down into the tank.
7. Put everything back together carefully. You might want to replace the small O ring at the fitting if it is worn out.
8. Run vinegar through the system, or CLR or some other solvent that can break down the hard water residue. Plug in the unit and flush the system with cleaner but make sure to get it all out. Run alot of clean water through it.
** you might be able to just run CLR or Vinegar or some other cleaner through the system, without disassembly. I am not an expert in these things, please find out what is safe to use before trying it. I am not responsible if you get poisoned!
Hope this helps some!

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.

Have you ever wondered, 'how do I descale my
expresso machine?' First lets us understand what is exactly is scaling.
The build up of minerals inside the hot parts of your coffee machine or
espresso machine is commonly called lime scale. When lime scale
builds up inside the Espresso machine, it slows down the water flow,
reduces the boiler capacity and can prevent your coffee machine from
working properly. To keep your Espresso machine operational at full
order, it is important to descale it every three months. The time
intervals between descaling depend upon many factors. Quality of your
water and the amount of water running through the machine are the two
main factors that decide the frequency at which you should descale your
Espresso machine. The more you your machine, more often should you
descale it. In some cities, in conjunction with a water filter you can
use your coffee machine for a year or more without descaling at all. If
you use less water by drinking espressos you'll need to descale less
often than if you make cappuccinos.
Descaling products are widely available from stores
that sell coffeemakers and espresso machines. Be sure that the product
you buy to descale your Espresso machine is intended for this specific
use only. Before you descale your Espresso machine, always unplug it and
make sure that it is cold. Also, never immerse the appliance in water
and nor should you use abrasive cleaning products
or scouring materials on any part of your Expresso machine. In case
your Espresso machine does not come with a instruction guide or booklet,
then use a proper citric acid based descaling solution designed for
espresso machines. This should be mixed and prepared as per the
instructions on the bottle or packet. Once your Espresso machine has
been descaled properly you would not be left wondering, 'how do I
descale my expresso machine?', treat yourself to a great cup of coffee.
