Water overfilling the ice tray is usually the result of high water pressure in the home. However, depending on the type of ice maker that your refrigerator has, troubleshooting can be performed to help correct this issue.
If your Twist-N-Serve ice maker is overfilling with water, this is usually the result of the water pressure being too high. Partially close the water valve going in to the refrigerator to reduce water pressure, or try purchasing a water pressure regulator to decrease the water pressure. This should resolve the issue by lowering the water pressure, so that too much water does not overfill the tray. This pressure regulator can be purchased from a local hardware store.
If your CustomCube™ ice maker is overfilling with water, this is usually the result of the SIZE SELECTOR being set too high. The size selector is to accommodate water pressure. Each increase in size will add a half second to the amount of time the fill tube is open. If the water pressure is high, it is necessary to select a smaller size. Otherwise, the water will overfill the tray.
If your 12 cube twist ice maker is overfilling with water, the flow sensor that determines how much water is flowing to the ice maker may be malfunctioning. If so, the ice maker reverts to a timed fill. If the water pressure is high, the tray may also overfill. To check, press and hold the ‘ICE PLUS and FREEZER TEMP buttons at the same time. If ‘gF’ displays on the control panel, service is required. Partially close the water valve to reduce water pressure until service is complete.
