If you want to you can wire the washing machine into an unfused

unfused 15A socket below the worktop.
A FCU with a 'BS1363' type plug fuse in it can be over ridden,
leaving the appliance protected at 30A, a 15A fuse-less socket would
have to be a radial anyway.

A 15A unfused socket (of course it's actually the plug that's unfused)
can be downstream of a 13A FCU on a ring.

You seem to be obsessed with people deviously short-circuiting plug
fuses, which I've never seen or heard of actually happening.

Nails in 30A rewriable fuses perhaps, but that's usually because the
wiring is f'cked anyway so the fuse keeps blowing.

Anyway, it only takes a moment to move a wire from a 16A socket MCB to
the 45A shower MCB in the CU.
