don't think you need to open anything if new. What he failed to sate here is you do this when there is no heat. Also I am not sure why he doesn't recommend continuity check here, maybe there is something I don't know. How about the thermal fuses, how do you remove and check those?
@@lelitinsider2977 ok thanks! Do I need to remove the first 2 buttons to be able to reach the hot water button? Is it just a cluck mount, or how is the button mountef? Are the elevtrical wires just to pull off, or need a tool? Thxs for support!
