I am out of rinse aid (and am disinclined to make a special trip to the
supermarket to buy some)

can I make some more by watering down washing up liquid, or will that not
work?

Get some genuine stuff. Amazon's best seller:

https://www.amazon.co.uk/Finish-Rins.../dp/B0080OXKXM

2 x 800ml Finish rinse aid, choice of Original or Lemon, free delivery.

Get some dishwasher powder/tabs while you're at it...
