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).
