Thanks #Hotpoint for this design flaw.
The offset PCB button pressing finger broke off at an obvious weak point, a few mg of plastic to reinforce it would have cost nothing.
Impossible to glue or otherwise #repair.
Hotpoint wanted 12 quid for a replacement piece of plastic which should have been free issue as it's a design flaw. Then to add insult to injury they added 7 pounds for shipping.
Why not line up the outside button with the PCB one inside as on the earlier mark of this machine?
