Hi Lisa, you may have a couple of faults.The snowflake usually means that the rinse aid needs topping up.On these models the red lights are salt and rinse aid and the green lights are the prog lights. It may be that the door lock is faulty so will not let you select a prog.I think an engineer visit may be best.Glen Dimplex / Stoves engineers repair these appliances now.
