Question about Alessi "Coban" Espresso Machine
Just got hold of one of these lovely machines. Hasn't been used for 10 years. Works well, though te coffee tastes a little bitter. Thought i'd better descale it, as i'm sure it's never been done. How do you go about it?

I had the same problem. There is ONE authorised dealer for Alessi in Italy. They are Arthur Eugster Italia srl, in Asti (Piemonte). I don't have the contact number, but my friend in Italy got a complete set of seals from them, FREE OF CHARGE (don't ask me how he got it) and sent to me in Australia. Good luck

EXPLANATION: It is normal at that type of machines when they stay long unused you may have trouble with pump. The pump has 2 non return valves, very small and very sensitive ones. If they don't work properly the piston of pump cant pump watter for brewing coffee. SOLUTION: 1 - You should replace the pump, it will provide pressure and you will be able to get coffee from coffee brewing outlet 2 - (in case you cant get new pump fast enough) You open the pump carefully, the non return valves are in outlet part of pump. Before opening you can try blowing with compressed air = 4 bar (5-10 seconds) many times that helps to get in order the valves without opening pump.

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.

How long does it take for your machine to grind for 1 cup? Longer then 10 seconds? Grinder setting?
Descaling should be done every 2-3 regardless if the light comes on or not. To reset the light hold the steam button until the light goes off.
