Indesit iwc 6153 override door lock

My problem is that I cannot open my washing machine door and I believe it is the lock which is at fault not the door's physical mechanism. I need help to override the lock or to know how to break off the interlock without damaging anything else.

Key points

Machine tripped electrics or electrics tripped causing an error message of all lights flashing.

Machine was empty of water.

The door lock light remained on, I tried every combination of cycle and the light always remained on.

Leaving the machine off for hours does not reset it.

I have cleared the drain.

I have removed the control board and no visible capacitors blown.

I have tried using a string to open the door.

I have removed the lid and disconnected the power from the interlock.

If I pull the handle the metal hook moves easily, I can feel this when touching the interlock.

I have tried bashing the interlock in case this releases it.

I have checked the manual for any override codes.

Any help gratefully received in forcing the door open or how best to remove the interlock from the inside.
