Hello Larry,

I would certainly try Dezcal or Calcinet. I use Calcinet because it comes in
1kg cans and my local espresso repair supply carries it. Also, it's
astonishing how much descaling solution it can take. I descaled a commercial
2 group machine and it took a week or more and almost 2kg of Calcinet to get
rid of the scale. And I was able to chip a lot of the scale off the heater
and inside of the boiler or it probably would have taken a third kg. If any
water flows it should work. It works much better when it's warm.
I left 1/3 of the 220V element in the boiler hooked up to keep the water
warm the whole time. Descaling is not hard, but if the pipes are scaled
badly on the inside it works a lot better if you take them out. I stood mine
at an angle in a tall stainless pot so the bubbles would keep the solution
circulating in the pipes.

Lastly, it's not uncommon for machines to clog small passages with small
particles of stuff left after descaling.

Where is the machine located?
