Daikin Altherma 3, error 7H-06, cleaning the heat pump filter, repair with your own hands (DIY)

When error 7H-06 appeared, the heat pump stopped working. I removed the heat pump filter, washed it and put it back. After that the heat pump worked perfectly!

Interesting and insightful. What was the origin of the scales found in the filter? It seemed that there was a problem elsewhere in the piping system. It is possible that these deposits may build-up at a greater rate if the core problem is not identified. I am not a specialist about these things but they looked like flakes from the inner wall of the piping. I hope you will not get this problem anymore but even if you do, at least you know how to clean the filter. Many thanks for the video.
