Washer dryer question

The fire risk was leaving them running when going out in very rare cases where there was a build up of lint/fluff.
No more risk leaving it turned on at the socket when it is not operating than with any other white goods.

Turned off my switch in my current house and I heard a hissing noise. I had to get an electrician so are these isolator switches meant it be switched on 24/7? I was always told turn off a tumble dryer as it’s a fire risk to leave them on I assume a washer dryer operates differently?

I think it is more that you are not supposed to leave tumble driers, or washing machines for that matter, actually running when there is no one around.
