I heated the machine to brew temp... them switched it off and let the pressure in the tank force the water through the hot water tap into a jug... about 500ml came out..
Then added 50g of descaler to that water... added a further 400ml of cold water to the jug then put the water drawing pipes into that jug and turned the machine on... which then drew the descaler solution into the tank,,,, opened the steam wand for 15 secs to get some in there once it was up to temp,,, and the same for the hot water dispenser.. then ran it through the grouphead for 45 secs or so
then turned it off and let it sit for an hour or so...
after that its just been a case of filling the water tank with clean water... turning it on.. letting it draw clean water in and then once up to temp,,, turning off and opening the hot water tap and letting the internal pressure force the water out....
rinse and repeat..
