Servus beinand,
I got a Jura F50 for my home use as a gift. This I have decalcified, disassembled and cleaned. The machine had about 10k cups down. The grinder has already been replaced. At first I had the problem that the coffee was only 50 degrees warm. Temperature sensor at the thermocouple exchanged, clearly better. to 60 degrees.
With the thermocouple version 2 (plug connections) the water flow is 1a when rinsing with syringe. They say the thermocouple has a stainless steel wire running through it. On both sides I can insert a wire that stops at exactly the same length on both sides. I.e. for me, the wires are broken in the core.
Here's the deal: When I run the machine, coffee and hot water everything is ok. As soon as you switch to steam, you have silver little metal shavings in the in the steam water!
Disassembled everything individually, rinsed again by hand until everything is clean. Machine operated with steam, again shavings. Done twice, always with the same result....
I have no desire to consume aluminum in this quantity. Is it really the thermocouple or could it come from somewhere else?
Replacing the element would mean water contact with aluminium again, but "for now" no chips.
