Hi Pauline, it may be a model ADP8224 or ADP 8234 etc and this one was made by SMEG.The control panel will have broken inside.The only way to go is pull the door to break the internal part of the panel and then fit a new panel.They are not that expensive but you will need the model number.It is on the inner edge of the door.
All the best.
