Hi,

need more information as a product number or type, this is on the door of the unit. Reason is this unit was built to be used world wide and my last count was 15 water valve can be used or ordered for this unit. But to answer your question the unit is filling when not in use, this is cause by the water valve not closing completely. You will need to have this replaced. Now when you order this make sure you have the type or product number and if it was produced before or after June of 2001. Very Important so you get the correct part. Good Luck

I’m happy to help further over the phone at https://www.6ya.com/expert/gere_bf68e6055dd61249
