Dishwasher door sorted
Well, Ray came this morning (only 2 hours after the time he said he'd be arriving) and fixed the dishwasher door (cut a chunk out of the plinth to stop the door from catching,)
It all seems OK now.
Totally separate from KK, we had hassles with a blocked drain tonight.... but I finally got the pipe clear.
Checked with Ray from KK and it appears that it is normal for the extractor hood chimney trim to be loosely slotted in place.
Just need to wait now till the corgi certificate tunrs up!
