If Hotpoint design their dishwashers with the same care and attention they use for their fridge freezers then you'd be better off washing your dishes in the toaster and browning your toast in the dishwasher.
A Hotpoint oven, on full blast, keeps food at a lower temperature than the fridge compartment on a 'frost free' Hotpoint fridge freezer.
'Frost free' being yet another Hotpoint lie.
