Welcome to the site Rob.
I have seen them patched up in the past with a little silicone sealer (left to set for a day or two of course). That or fabricating your own replacement is the only answer here.
As noted, Dyson wont supply these seals on their own - and they really should IMO.
(They like to read here so we hope someone might pass that one along ). Personally, if the machine is in warranty, I would call them again to complain about the pants service you have received. Taking a few screws out is no hardship for a practical fellow to ascertain the nature of what we must assume to be a
design fault. If you chew their ear a bit and ask to speak to a manager, my bet is they will cough up a replacement cyclone - as they should.
To be fair, their customer service usually isn't too bad, and something like that seal really shouldn't fail in such a short time since the DC33 was launched.
'Invalidation of warranty' is a get out. It may be technically correct, but as they value their reputation, the ten quid or so a cyclone unit must cost them to make is pocket change for a company that wants decent PR.
What they *really* don't want is people writing about their *potential* design faults on the net.
A potential customer might just read
this it and clear off and buy a
Hoover instead.
(Did I say Hoover? Wash my mouth with soapy water. I never got my Florida flights from them in the 90's....)A polite, yet insistent email, together with a link to this topic, *might* just change their mind. Wouldn't it be nice if you could come back to the topic and say they came through and the customer service is superb after all?
