I have had my Elektra about a month. I pull about 5 shots per day. The water I use is Crystal Geyser filtered through a Brita pitcher (that filters nothing else). I am thinking I should descale. Here are instructions i have been given.

"Use one pouch of cleancaf per month. Mix as instructed with water, then use the refill button to fill the boiler all the way to the top. This should be done with the machine cold. You will know it hits the top once water squirts out below the bowl. then press the coffee button and let run through the grouphead until blue solution comes out. Shut off/power down machine.

b) Let it sit overnight.

c) Next day, remove the steam arm, place the exit valve over a sink, and open the steam valve. Let the solution drain out. You will need to turn the machine on its side several times to get everything out.

d) Repeat step A with regular water 3 times to make sure all the solution comes out."

I would appreciate any suggestions or revisions on this method.

Mark's detailed review offers some thoughts on cleaning and descaling the Microcasa:

Cleaning the boiler can be done with standard purocaff cleaner, but be wary of using it too much and also be warned - cleaning out the entire boiler means you also have to flush out the site glass pipe on the left side of the machine - you'll have to do some serious sloshing around to clean everything, so get your man-handle boots on and get ready to do a firm-grip jig with this thing cradled in your arms - you literally need that kind of strong grip and force to shake, rattle and roll liquid through this machine. I'd do a descaling clean as infrequently as possible with the machine.

Note: I've not heard of using Purocaff on the Microcasa (TSP / trisodium phosphate); sounds a little harsh. Of the commercially available stuff, I've only used Cleancaf (which is a mild detergent and citric acid solution). Steve mentioned that vinegar will work if you're willing to spend a little extra time rinsing. Finally, Jim's Water FAQ recommends citric acid, which you can buy at brewer's and soapmaker's supply stores.
