Hello experts!
I am asking for a expert's advise on my leaking la nuova Cuadra(Diamond Italy)!
Have opened up the machine, found a tube blown up going from pump to heat exchanger.
I have purchased the genuine part from the original supplier, which was teflon(PTFE) 4x6mm tube, and it was okay for 3 days and blown up again.
So have sourced another one, and the same thing happen. it blown up again in few days time.
So I did some research on Teflon Tube(PTFE), and it should hold up to 60 bar pressure, with 220C temperature. I think heat exchange would only go up to 15bar maximum and 100C temperature being it's water?, but as Photos below, its blown up. and I could not really understand why as the pressure and temperature is well lower than what the Teflon tube could resist.
Only possibility that I could think of I may snapped the tube while I install so it has the weak point, but I believe I did not snapped or fold it at all...
Not sure how I can attach photo from here, so sharing below google photo link
