Plumbing in a dishwasher and washing machine.

Should read "dual pattress", not "double". This essentially two single pattresses,, side by side, in the same moulding.

A big sign saying “don’t run washing machine and dishwasher at the same time!”

Thing is, there's only excess current drawn when both appliances are heating water at the same time. Dishwasher heats water for fairly long periods during it's cycle, but washing machines, with modern 'green' detergents and low temperature cycles are only drawing high currents for very short periods.

Without knowing exactly when each appliance is on its heating cycle…. Better just to have one on at a time.

Thanks for your help I will do that but I can’t understand the difference between this dual pattrass and double socket

t5he one you will be used to is for a double socket. the one he's referring to is slightly wider with a divider and inboard lugs so as to accept 2 single sockets side by side. reason for using 2 singles is that a single socket is rated 20A whweas a double is 20A total for both sides.

Bad practice, but just about acceptable. Unlikely to cause problems unless both appliances are regularly heating water at the same time.

Dishwasher is about 1800 kw washer 2000 kw if I have them on separate am I ok I will still use duel pattress
