gorenje f2 error

Hi I’m having trouble with a gorenje wa72145 started getting error f2 door lock so to try and get it going for the customer while the part is ordered I had a Hotpoint lock in the van that fits with the connection turned round , still f2 error so I bypassed the door lock with wires and the machine started to fill etc but after a minute or 2 the f2 error again ??

Any ideas ?

Thanks alan
