This washer is working as normal except that it is only letting a small amount of water in before deciding it has enough.
How do washers know when they are full? Is there likely to be a sensor somewhere?
Any input appreciated.

All the same, AFAIK. There's a plastic "pressure bottle" mounted on the drum low down, typically. There's a narrow rubber pipe up to the top of the casing, where the switch itself is mounted.. The switch is actually an air pressure switch, a large round diaphram with some over-centre springs mounted behind. Typically there are two or three different switches in there for different depths (and thus pressures).
If you take the hose off and blow gently, you should hear the switches clicking. A more careful test can involve filling the drum and putting a meter across the switch contacts. They rarely fail totally and when they do it's easily tested for. Most problems are actually with the plumbing to it not the switch itself. Over-filling is a leak in the hose, under-filling can be a blockage around the bottle. Even soap scum build-up inside the bottle can be enough to cause under-filling - take it off, throw a couple of nuts and bolts in there (or a Steradent tablet) and shake it clean.
As always, the Haynes washing machine manual is in your local library, well-thumbed and well worth a read.
Diaphragm switch, usually mounted on the side, circular thing of about
4" diameter with a tube conecting to the outer drum, I believe.
When was the last time it was put on a good wash? If it hasnn't been used above 50 deg c, try a boil wash to give it a good clean out with a descale sachet in there.
Tried that, no Joy
Hi, thanks for that, I will have a look tomorrow. We have replaced the washer, 'er indoors saw it as a unmissable opportunity to get a better one.
Its at work at the minute, I figured it does no harm to have a spare.
I never knew such a thing existed.
Tell her indoors on that basis you'll have a new better one next time she has a fault.
