    Hey guys,
    I have a weird one. My logic Combi ES35 in my home from time to time when it's on, makes a humming noise. the weird thing is you can make it go away by gently placing hand on the outer casing (see video attached). Does anyone have any ideas on what could be and what to check over incase it is something simple?

    The case is vibrating probably in resonance with the pump vibration. As it's in a cupboard I suggest that you stick a strip of foam backed tape on the side, as wide and as long as you can, this will dampen the vibration and reduce the noise.
