How can I reset my Asko w6661 overflow fault detection?

I hosed out the inside of my front loader Asko w6661 causing an overflow fault detection. The pump will constantly drain even when there is no water left. The door will not open unless the emergency door release is used and no washing program can be initiated. I have left the macine off for many hours but it immediately pumps when turned on again. I have also manually drained all water using the front drain bung. There will be a simple reset process only known to a tech. Any assistance will be greatly appreciated.
