Tpa blocking up?

Ours has a removable nozzle. Quick soak in vinegar - job done.

Agreed. Look in the discharge, and see if there is an insert in there with a filter mesh. Remove, de-scale, re-insert. And install a water softener for the whole house.

Right - passed on.

It seems there was one when they bought the house - but had it removed. ;-)

Have to admit, I couldn't see the Thyroid angle here. :-)

Bad, bad move! Remove a defective/dead one, yes, but replace it with a new one, surely? That's what we did.

I'm told you had to dismantle a kitchen unit to re-fill it. And that there was no place for a dishwasher. So they decided to get rid and put a dishwasher in its place.

I'm in a hard water area and it's not a priority for me. I actually prefer the feel of hard water when washing.

The unit that was here when we moved in was a dead Calgon pellet type, and refilling it would have needed a contortionist. We replaced it with a unit that uses block salt, which is just dropped in with ease. I cannot easily explain it here, but that is the fact of it. A totally different approach, which now works just fine. As to preferring hard water, each to his own! Having seen the reduction in scale on taps etc, I have no doubt that having one here in East Anglia is worth it.
