fisher paykel smartdrive 608 error?

my washing machine has done this several times before so im pretty sure it doesnt need replacement. when the mains power goes out eg blackout, at a certain times during the cycle. the computer malfunctions and beeps continuously, with three lights on. the water goes in but in spurts and the spin is intermittent. previously i have fixed this with alot of fiddling and eventually the machine has just gone. though my efforts have not been successful this time and was wondering if there was a reset procedure. i have unplugged and repluged after an hour. any help cheers.
