Hi all
,My ci went bye bye a few days ago after a hot water draw with hot hiss. Both thermal fuses were blown. Have ordered boiler, 2 thermo fuses and temperature sensor. Boiler measured and compare with the values of the new - both 38 ohm. So old left in. Old temperature sensor also had the same resistance value as the new one, but I installed the new one. Both thermal fuses were through, the new were 184 °, but I ordered extra with stranded wire suitable for the Melitta ci, so should fit. All assembled and after 4 coffee cups again exactly the same.

Now I'm a bit at a loss as to what it can be. Triac durchgemessen and both power connections had no continuity, as it should probably be.

Does anyone have any idea what it may be?
