Underwire stuck in drum?

How do i get an underwire from a bra out of my drum. I have a Zanussi washing machine (ZWF 1621 W) and the wire has gone through the drum and is not protruding through any holes. and is between the steel drum and the plastic caseing.
It does not appear to be near the pump hose, more towards the top of the drum.
If i leave it will it eventually damage the plastic drum casing?
The machine is only 6 months old.
