integrated dishwasher

[Arfa]

nothing stopping the arms spinning, don't use rinse aid after an engineer told me its not needed and can actually be detrimental to the machine......said their Co. always tell the punter not to use it
filters seem ok so I'm at a bit of a loss.........what's the best way to clean the jets in the arms?

Interesting. Not heard this one. I know some tablet are combined detergent, salt and rinse aid - with many washer than having some button combo your use to disable the warning about low salt/rinse aid. Don't use these myself. But we often notice the machine is low on rinse aid before the low light comes on as you get a load of stuff with crap stuck to it. And it's usually fine again after filling up. No idea, research it some more, or maybe give some a go.
