Hi sometimes if there is a blockidge in the pump-filter or the pump is not working then it might stop the machine from spinning,
at the bottom of the machine is normaly along cover that you need to take off,or a little door,put a container under neath and open the little screw in door and see if there is something stuck or hair or any obstruction.
hope this was some help,all the best.

May be the switch is loose try fixing it with ascrew driver or the rubber hose is not fixed properly and the machine pump is taking air or the pump failure

It is difficult to answer the question with so few symptoms. The question would be whether the pump stops when you open the door? If not, then should checked for correct door switch, otherwise I think you need to replace the main board. If you see diagram bellow you can see that the motor is driven by the triac which is probable remain in the open position and constantly power supply motor. Some model has relay which switch between wash motor and drain motor and there is possible that relay stuck and motor also running constantly.

un plug the machine

Hi below is the meaning of the error code and corrective actions needed. To open the door manually take the panel out from under the door and reach up to the door lock mechanism. On the door lock there is a tab, pull the tab and this will release the door. If you have any questions please feel free to ask. Mike

you shouldnt be able to open door if there is water in it. sounds like your door interlock has burnt out and probably taken the main printed circuit board with it.

Sounds like pump has packed up,switch of electric and unplug open back of machine see if pump drive belt has come off or is damaged its quite a common fault

Hi,

Don't mean to sound blunt or short in my suggestion but it sounds like a visit from the Service Force Team who deal with Zanussi repairs & spares.

Hi there ....this condition is ususally caused by a water leak into the sump of the dishwasher which activates a safety switch to run the drain pump..preventing the appliance from being used....Remedy...tip the dishwasher back in the head allowing excess water to exit from the sump...then with the door open check that the air vent lock ring is secure, thet the salt unit retaining ring is secure..and finally that the filter unit to base screws are secure...this done re-start and you should b fine
