In the next few weeks, a new washing machine will be purchased.

The old WM has been quite good but, like so many, ended up with the
usual black mould round the door seal. Is there anything that can be
done to a new machine to inhibit black mould for the rest of its life?

Run it for one cycle at 90deg C (or whatever its maximum temperature
is) at least once a month. The problem is worse using "green" low
temperature detergents which do not inhibit mould growth.

Leave the door open or ajar when not in use

Yes.
And if not using a septic system, adding a bit of bleach to the boil wash.
Also - don't shut the door when the machine is not in use.

Every couple of months run this hot cycle (possibly without a load) with
a packet of washing soda - this gets rid of any smells by removing any
build up of (human) fat and congealed detergent in the drum/pipes/pumps.

Guide price less than 1 GBP per kg in many supermarkets.

Try taking out the detergent dispenser tray and then looking upwards to
where the water enters to wash the detergent into the machine. You may
not see too much if you normally put the detergent in to the drum.

A hand operated spray bottle filled with diluted bleach/vinegar and a
old toothbrush can deal with the housing, followed by a quick rinse
cycle. A soak in a bucket or a trip through the dish washer can deal
with the drawer.

As my machine is not in the kitchen, a quick blast with the garden hose

Over use can damage the rubbers - but occasional seems OK. The
alternative is shove some bleaching agent that's rated for washing
machines, eg Vanish, in.

One thing not yet mentioned is to do a hot wash now & then with acid, eg citric acid. This is to remove limescale, which provides a layer of scale/muck that mould likes to grow on/in.

The operator of the spray bottle needs to have some of what used to be
called mechanical sympathy in they way a machine is treated, i don't
know of an updated term to encompass stuff with electronics.
However my missus hasn't got it and proceeded to spray such a solution
with wild enthusiasm and managed to get some into the electronic
circuits some of which are mounted in the door the result being an
inoperable machine and a display showing every option available.

Fortunatly it responded to a clean with IPA and gentle warmth from a
hairdryer and has been OK for the 3 years since she did it.

Well I always wipe it around, but I suppose the rubber itself, after a time
gets roughened and makes it hard to keep clean, and the chemicals presumably
do aid growth. I'd have though some kind of anti fungal agent would be put
in the powder or liquid to hel with this.

My W/D basically gets used on "cool synthetics" cycle for most clothes
and "hot cotton" cycle for towels, this keeps the machine clean, or so I
thought ...

I bought a non-iron cotton white shirt for a funeral, washed it on
synthetics, no problem, line-dried it, unlike 70's drip-dry I decided I
absolutely couldn't improve on the finish by ironing it, wore it, went
to wash it again before putting it away and noticed it should have been
washed as "wool" I don't think I've ever used the wool cycle before (I
use blubber instead of jumpers) so anyway I washed it on wool, and it
came out ABSOLUTELY caked in black fluff.

Turns out the wool programme is quite different from the normal washes;
I expected it to be slower and shorter to be more delicate, but
counter-intuitively it is a LOT faster, so centrifugal* force keeps the
load pinned to the drum rather than letting it tumble and agitate. This
action must have loosened 9 years worth of accumulated crud from between
the fixed and rotating drums.

In fact, SO much crud that even after half a dozen washes on the wool
cycle and boil cycle, some with a load, some empty, some with a dose of
W/M cleaner, some with an extra gallon of boiling water added via the
soap tray, the thing was still coating any clothes with black fluff.

Result? I washed the white shirt on synthetics and vowed never to use
the wool cycle ever again.

Doesn't bleach react with some plastics making them brittle or
discoloured?
Maybe Bosch uses some plastic components that could be affected,
though a quick rinse or wipe would not be as risky as a prolonged
soak.

Washing machine outer drums are often made from polyester resin (GRP).
Bleach (particularly warm or hot) will damage the polyester resin, and
you definitely don't want an outer drum to fail at high stress when
the machine is spinning at top speed. A few times over the life of the
machine might not be a problem, but doing it routinely might be asking
for trouble.

The only place I see black mold form is in the farbic softener
dispensor. I simply clean it a couple of times a year. I never do
boil washes - most of my washes are 40C (35C really) with occasional
60C (50C really) for towels. This is using Persil Bio. As someone else
said, eco powders maybe your problem - they certainly don't clean as
well, so I wouldn't be surprised.

Thanks - but the worst bit is on the door seal outside the point to

going to work.

Had been thinking of a surface treatment with something that deposits a

Same here. Also Bio-D liquid (v. similar to Ecover). Usually wash at 30C as
well, so asking for trouble.
The machine's a 'John Lewis', so really AEG. The door seal drains well and
can be wiped out easily. The drawer has never had mould in it but there has
been a few small spots in its cavity.
I looked in the pump housing after a year and it was clean - the old machine
was a mushroom farm in there!

Our we talking about the inner ring/ the well of the dear seal? If so,
it is common all over. Which bemuses me given the detergent atmosphere.
Maybe someone in here can enlighten me?

Anyway, get your hand stuck in. A heavy rag soaked in vinegar will rid
them. And, if it bothers you to, rinse your hands in vinegar, too. Very
good for the skin a naturally symbiotic with human bacteria.
