Do you know what these pipe connections are?

nobody has said its a water supply to a white good appliance

So they is only connected to the washing machine and dish washer?

Yep. Spot on. Good on Quality for pointing out the 'bleedin' obvious (to US)

Can't quite work out why the water seemed the first few months but now hard again. How can i confirm if it has a scale reducer?

I think you will find dishwashers have built in softeners, which is why you have to put salt in them. Try using rinse aid.

The clear glasses and cutlery was from normal tap washing so that mystery is still there.

Thanks all.

If you are describing glasses that have gone 'cloudy' after washing in a dishwasher, try soaking a sample in warm vinegar for about 20 minutes.

If it comes out shiny then the problem was limescale due hard water and you just need to have a session vinegar-treating all your glasses.

If it's still cloudy the glass has been attacked (etched/corroded) by the dishwasher chemicals you are using. You can get formulations that claim not to do this but I don't think that the damage already done is reversible.
