I have a digital plug in timer which says on the back,
"Not suitable for dishwashers and washing machines".
The only reason I can think of is the inductance of the motor.
But it's rated at 3.2kW, and it uses a relay (I can hear it). So why?

Could be the electronics in the timer are not protected against transients
generated by the motor.

But you'd expect them to say "Not suitable for dishwashers and washing
machines or motors".
