How can I fix my ZWF 1241 W Zanussi Washing Machine?

Problem: All displays lights are flashing and machine beeping continuously, unable to select any program.
This machine was working fine when an item became lodged inside the drum. We pulled the seal away to retrieve it then the W/M started to leak. We tipped the W/M on its side (big mistake!) to check for the leak and realised we had split fabric conditioner onto the PCB, we have blasted it with hairdryer and have since sent it away to be checked, but No Fault found.
If anyone can help I would be really grateful.
Thanks Denise
