got in last night to find the kitchen flooded, short story is there was an
underwire sticking through the drum. tipped the machine up today and found a
small hole about 7mm punched in the drum casing. as the machine is 8 month's
old i was going to ring the repair place but should i decide to repair it
myself what would be the best adhesive for the job. i was thinking of
jb-weld, i have used it in the passed with success. my plan is to glue a
small plate of aluminium over the hole. any other suggestion's??

I would either:
Find a suitable bolt and nut, probably stainless.
Drill hole out to circular.
Bolt through hole, tighten nut quite a bit.

Or take a soldering iron, and weld the hole shut, using compatible plastic.
