I believe the problem lies in faulty ring antenna, some kind of manufacturing fault. This means they don't work as well as they should and therefore the system is more vulnerable to electromagnetic interference.
If it happens to you, you need a new ring piece. To get going again, turn the bike off and wheel it away from any possible sources of EM interference. This includes electrical power lines and kind of radio transmitter such as cellular masts, police equipment, and especially any ham radio equipment. This isn't guaranteed to work but its the best you can do and its better than waiting for a recovery truck.
Personally I'm quite happy with my existing ring piece, and no matter how many times EWS flashes I'm keeping it!
