Switching off socket trips rcd

[pjo123]

Hi all.

Have a washing machine plugged into a socket in the kitchen. Modern machine with computerised timer/display.

Twice in the past three months the washing machine has finished, I've turned the washing machine off at the machine hence LCD displays go off. Then I turn off the switch on the wall and as I'm flicking the switch, it trips the rcd.

The machine is in use a few times a week and has finished a cycle today with zero problems..

It's a 2gang DP socket with a power supply transformer for my radio plugged into (and switched on) the other side of the socket.

Is replacing the socket likely to solve the problem or is it likely to be something else please?

If its likely to be the socket, what's the best recommended make at the moment?

Thanks

Replace the socket (switch contacts could be worn/dirty and hence arcing) and ensure that you verify polarity after fitting the replacement (which should be done anyway!!)

Can you plug the washing machine into another socket on the same circuit,(via a short extension lead if necessary), and see if it still happens. If it does then you can rule out the socket being at fault.

Replace the socket, but get one with single pole switches, not DP.
