Zanussi washing machine fault codes - what do they mean?

FS1455W - Manual lists:

4 flashes and 4 beeps as door open
2 flashes and 2 beeps as water not drained
1 flash and 1 beep as water not filling

We get 3 flashes and 3 beeps... any ideas?

Symptoms are drum fills and washing cycle begins but less than one minute into cycle error code displays and drum drains.
