hotpoint aqxxl129pm water damage

went to look at this one today.customer told me that it leaked after the big freeze over christmas so she used to turn water on and off again after machine finished. she could not afford to get it repaired until she got paid at end of month.water coming off valve onto belt and spun onto power module.tripped power. obvious signs of spray. now completely dead.power to module ok.did not remove board but no obvious signs of damage on front (i know back will show more obvious signs) is it poss that control pcb could be damaged as a result or will i get away with power module.have given it the hairdryer treatment.paul
