Carimali Bubble With X011 Grinder

Beautiful Machine but water not hot enough

We love the machine, but the customer comments are that the water is not hot enough. It says 123 degrees on the front but the hot water tap coming out is at 70 degrees and they can drink it straight away. Otherwise people love the coffee say it tastes amazing. The grinder sits between 0-1 to get the coffee grounds fine enough, this doesnt seem right as when the blades get a little blunter we will not be able to make it finer.
