If your appliance door is no longer locking then you may have a fault with the door interlock. If the interlock on your washing machine is faulty it will prevent your washing machine from working. The interlock plays an important role on your appliance as it is designed to give a time delay of about 2 minutes from the end of the wash/dry cycle before you can then open the door - an important safety feature. Without an effective working interlock the washing machine will not start so this new replacement interlock could get your appliance back in full working order once again. Please check model fit list to ensure this part is correct for your model.
