Possibly a loose connection behind the outlet (or the outlet itself) that momentarily cuts power to the hood, causing it to drop into standby.
It could be that the coffee machine has a mains filter (including capacitors) across the power input before the on/off switch, and the act of plugging it in creates EMC interference (a spike) that upsets the cooker hood controller. I don't think it's necessarily anything sinister.Thank you, Could it be due to interference between electronic components in the espresso machine and the touch hood keyboard?
