Yesterday I decalcified my Moccamaster, also gave it a cleaning cycle to remove the coffee oils and I took the WMF coffee grinder apart to give it a thorough cleaning too. This morning I enjoyed the result. A damn fine cup of Libertad coffee :) #Mehpost
Moccamaster says it is sufficient to decalcify after 100 runs, but the very hard water here in Munich calls for a monthly cycle. And never use citric acid for that! The heating element in a Moccamaster is pure copper, so it calls for (UPDATE) lactic acid instead, according to Technivorm. And as I plan to keep this machine working for many, many years, I will follow their guidelines slavishly ;)
@jwildeboer Lactic acid is better. I don't know exactly why, but I buy the original decalcifyier (lactic acid - based) from DeLonghi® for our Dedica® machine.
And using Brita® filtered water for brewing.

@jwildeboer the electronic of our Dedica machine offers many sophisticated options for settings and special modes by using special "sequences" of the three buttons & LED panel.

I can use among other things three settings for water hardness, which will trigger (after e.g. 100, 200, 300) an half automatic decalcifying mode.
The right button will blinking with orange backlight, if U confirm w/ special button pushing, and fill in the decalcifying solution, a special pump-pulsating rhythm starts.

@jwildeboer Twin Peaks reached. 😁
@jwildeboer I normally use a mixture of acetic acid and water for decalcifying kettles, coffee machines etc. Works very well
@jwildeboer thanks, made me have a closer look at the cleaning habits and possible cue for having conversations on taste
@jwildeboer keeping everything clean that is involved in preparing coffee is indeed key for having an excellent cup of coffee. We are having hard water here as well, therefore I only use filtered water and am able to decide if the filter needs to be changed based on the taste of my coffee. Highly recommended ☕️

30 years ago I bought an Italian Saeco bean-to-cup 14 bar, espresso machine. Electromechanical. And simple. I was advised to use only filtered water. Which I did. After 26 years of daily use with Munich water, and never de-calking, ever, it was still working well. Just a bit leaky. So I upgraded. And still always filter the water in the new one. Which has electronics this time. LED lights. But no essential OLED display, showing cup filling animations.
So I'm hugely convinced of filtering Munich water.
