GE Ice Maker Error Code Water icon and REPLACE FILTER on

This display combination indicates a water level sensor error has occurred. The ice maker's control board is not receiving a valid signal from the sensor that monitors water volume in the reservoir. This prevents the unit from confirming it has the correct amount of water to run a freeze cycle, so ice production stops until the issue is resolved.

A reset may temporarily clear the display, but the error will return if the underlying cause has not been addressed. The water level sensor error is triggered by an active fault condition, so the sensor, its connections, and the water supply should all be diagnosed and corrected before relying on a reset to restore normal operation.

If only cleaning or reconnecting the sensor is needed, there may be little to no parts cost, with any expense coming from a service call fee, which typically ranges from $75 to $150. If the water level sensor itself requires replacement, parts generally range from $20 to $80 depending on the model. A control board replacement, needed only in rare cases, can cost between $100 and $300 or more for parts alone.

Start by inspecting the water level sensor and its wiring harness for loose connectors, corrosion, or mineral deposits. Clean any scale buildup from the sensor and reseat all electrical connections. If the sensor does not operate correctly after cleaning and reconnection, it will need to be replaced. Also verify that the water supply line and inlet valve are delivering adequate water flow to the unit.

The ice maker will typically stop producing ice when this error is active, so there is no immediate safety hazard from the unit running in a compromised state. However, you should not attempt to bypass the sensor or ignore the fault, as the water level sensor is a control component that protects the unit from running without proper water. Address the error before resuming use.
