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.

I did have one hose start to leak.

IIRC it was at the end of the hose - there was a metal bit crimped to
the hose or something where it joined onto the screwy bit.

Exactly like mine, in fact!

Only a slow leak though

Yeah, but when you're away on holiday...?
