Brand new dishwasher arrived today, yay!
Except my Morrisons order just arrived and they didn't have the salt in stock so I don't have any.
Is it OK to run it for the first time without salt, or do I need to wait until I can get hold of some? I have left all of the washing up all day so really don't want to have to do it now 
Ps Morrisons also substituted my veggie sausages for meat ones so they are not in my good books today.
