A:Answer Hi - Thanks for choosing GE PWE23KMKES! We are sorry for the delay in responding. If your icemaker will not be used for some time (vacation, storage, etc.), we recommend that you shut off the water supply to the refrigerator and turn off the icemaker. If you turn off the water supply, make sure you also turn off the icemaker (use the Ice Make button on the control panel). For reference, see pages 12 and 23 of the Use and Care Manual at this link: https://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-60792-3.pdf - Safe travels!
