Hey guys! After some time we figured out the problem. Didn't write the full story previously cos I never considered it important, but long story short. I've had a circulation motor which stopped working, someone came and changed the motor to a new one. But as it turnes out, my old motor was designed for 24hour circulation, while the new one is not. Theoretically the in.k600 control should be able to (depending on spa setup) program purge cycles (mine was set up like this because of the 24hour circulation) or filter cycles. I guess the best solution would be to program the filter cycle, but I can't find the menu for it. I'm guessing there is some way to choose between purge or filter cycle, and it was done when the installation happened. Is there any way I can find it and set it up? is there like a master setting? thanks
