Hello dear people, the Sufu spits out a lot on this topic, but nothing that I can so easily connect MeinV 70, Built 2000, 140 HP has slight waste water loss I have to drop off and then something, I have excluded the heat exchanger so far because my carpets in the footroom are all dry. Today I changed the preliminary resistance from the blower, but I noticed that all cables in the area are slightly damp, from touching clearly cool water. Could that come from the defective or leaky heat exchanger? Thank you and greeting from VB, Peter
