WF320 - On/Off and Wash Enhance Flashing?

Hello, my WF320 started over filling, and over draining - combined with the ON/OFF Button and Wash Enhance Button flashing.

I checked the pressure switch, cleaned the filter, checked all connections etc etc.

Most hotpoint machines with a digital display give the E/F code translations, but this machine has no display.

The machine is little over 18months old and has little use. If only Hotpoint could tell me what the combined flashing buttons mean?

Can anybody shed some light?

thanks,
