I was thinking last night that if you can use soda crystals to wash the inside of the machine it may be possible to use it to clean your dishes.
They are alkaline enough (ph11) and I know that dishwasher powder is alkaline also.
I looked on google and it seems other people use a half and half mix of borax and washing soda eg one table spoon of each.
But wll I break my machine? it's new and DH would kill me if I did.
