A washer-dryer manual says the inlet hose should be screwed on so that
it points down at about 45° from vertical (either way) but not
vertical or horizontal. I'm just curious --- why does that matter?

(As is usual, the hose supplied has a 90° bend just before the
screw-on coupling, so the hose has to be parallel to the back of the
machine but could "point" in any direction in that plane.)

The inlet hoses of my washing machines have always pretty much pointed
straight down. The main hose problem is that the machine has to be
pushed back into hole between two cupboards and below a worktop.

I suggest that you ask the manufacturer, and let us know the response.

I couldn't see any rationale either. My only criterion would be
minimising strain when in position and during access.

Maybe the angle make the hose less likely to become strained while
you're shoving the appliance into the slot?

The usually reason is they do not want the hose to get trapped anywhere
or
crushed by trying to bend 90 degrees to undo the 90 degrees it would be at
if you use sods law and an angle horizontal or vertical.
That was what the bloke told me some years ago, but it seems a lame excuse
to me.
Also why are all machine c cold fill only? I'd have thought a mixer would
save poer on internal heaters.

In most houses, the hot water is not instantly available. You need to flush
out the cold water before hot reaches the appliance, by which time the
machine has got enough water.

Most modern machines use a tiny amount of water for the actual wash. So
would need a means of measuring (and wasting) the water until it ran hot.

Machines need to start with a cold wash to remove common staining that
an instant hot wash may cook in. The machine already has enough water
for the full wash when performing this initial cold wash and doesn't
need to top up with any more water.

If you inject v hot water into the machine you could damage synthetic
fabrics.

Unless you're washing dishes (or something like that) at the same
time, doesn't that mean you're wasting even more water?

That's about all I can come up with as well. Assuming that the supply
end of the hose has a straight connector and that the supply pipe
also has a straight connector meaning the joint is parallel with the
wall.

I think, as has been hinted, it is to encourage the pipe to form a
circular loop which can be safely pushed close to the wall.

That makes sense.

Next question --- why is the drain hose, which is permanently
attached to the machine (unless you open it up) made of such flimsy
material?

It has to be flexible. It does not have to be strong because it sees no
internal pressure.

I was thinking about it getting easily "crunched" while you're shoving
the appliance back into the slot.

All the ones Ive come across have more than adequate crush resistance. Id
wager you could stand on it without it crushing. Mind you, someone
somewhere might make a crushable one.

Well, I happened to take one out recently and noticed that the outlet
hose had been crunched (but was not leaking) --- and the last person
to move it out & back into place was a technician.
