Installed my first ISE d/w this week which was sold on the save the planet ticket to a customer with a cupboard full of Ecover & similar stuff.
Did the demo and got the question “Why isn’t there a rinse program?”
Thinking on my feet I replied “The designers took it out because it is not needed as this is a AAA rated appliance and it prevents waste of precious water”
So what is the real reason in case I get asked again?
