Should washing machine hoses be replaced every ten years?

Some years ago I noticed that the pressure rating dropped rapidly with
temperature. Not a problem on indirect HW, but a combi feed would rise
close
to mains pressure when shut off, so if the hose is full of hot water...
About 15 years ago I installed a Miele - the hose was rated above any
mains
pressure at 90 deg. C.
Hoses are cheap, but I'm always wary of a new one being worse than the
original one. My last machine, an AEG, was OK for 13 years, so hoses were
good then.
I asked a plumber I know if he's seen any old appliance hoses look bad
(perished) after 10+ years. No was the answer.
I suspect these days, the hose will outlive the machine mechanics.
The main thing to check is if they've been damaged (kinked, cut etc).
Agreed.
These days they tend to have a PVC cladding, which eliminates Ozone and
UV attack on the rubber (not that they usually see much light). And of
course machines have been cold fill only for a long time now. I think
the only failure I have seen was at the cheap and nasty coupling, where
one of the "nuts" pinged out one thread a few weeks after (someone else)
fitted it.
Well, my 10-year-old Hotpoint has both hot and cold hoses. It works
fine, though, even if the hot water is only tepid. Just has to heat
more itself, I assume.
