Are they old appliances on a new ring and did you have RCD protection before?

it could be a faulty pump or something within the washing machine/dryer ect itself. have you tried meggering the washing machine ect with 250v, to see if its that?

Hi george
my dishwasher did the same thing as whats happening to your installation the rcd went after 30 mins of the dishwasher switching on.The heating element was breaking down and going to earth hence tripping the rcd on that side of the board.new element fitted no more tripping !! by what your saying it can only be the appliances or combined causing your problem me thinks.
