We have just moved into a new house with a Diplomat kitchen and the above dishwasher.
We have a problem where the drawer which holds the dishwasher powder does not open during a cycle. I have searched in vain for a manual and found your site but can see no queries in the forum for this sort of error. I am getting no error lights at all. Any suggestions gratefully received.
Sounds like a faulty detergent dispenser solenoid if the plates are getting washed. Shop@ could help with this. Power off if you are going to look yourself.
