Airbus and pitot probes

This has been puzzling me for a while now ever since there have been suggestions that the pitot probes on the Air France A330 had become iced up - now there lies my question:

Surely airliners have Pitot heating, so why can they still freeze up - assuming the Pitot heat was turned on?
 
Pitot heat should have been on as a matter of procedure. There would have been ECAM warnings about the pitot heat being off. I think the problem lies in a design problem/malfunction with the specific pitot tube model used on that aircraft. Air France is replacing the affected pitot design with a different one.

Thanks for the reply, I'd not heard any news report mentioning pitot heat either, just thought it was odd.

May flight 447's passengers and crew rest in peace.
 
Some Airbus flights previously reported pitot tube drain hole blocked with debris.
This caused loss of airspeed indication in flight.
The replacement model is less prone to blockage.
