GE Ice Maker Error Code REPLACE FILTER flashing

The REPLACE FILTER flashing LED means the icemaker has detected that either the water filter is due for replacement or no filter is currently installed in the filter housing. The unit uses this alert to prompt the user to install or swap out the IMWF filter. The icemaker will continue to operate using an internal bypass, but water will not be filtered until the issue is addressed.

The icemaker has an internal bypass that allows it to continue producing ice even without a functioning filter installed. So the unit itself is not at risk of damage from continued use. However, ice produced without a working filter will not have the benefit of filtration, which can affect taste and clarity over time.

A simple reset is unlikely to permanently clear the REPLACE FILTER indicator if the underlying condition, such as a missing or overdue filter, has not been addressed. The alert is triggered by the filter detection system, so the correct resolution is to install a new IMWF filter. Once the icemaker detects a valid filter in the housing, the flashing LED should stop without requiring a manual reset.

Install a new IMWF water filter into the filter housing, making sure it is fully seated and locked into position. Once the icemaker detects the new filter correctly, the flashing LED should stop. If the light continues to flash, remove and reinstall the filter to confirm it is properly engaged, and verify that the filter part number is IMWF.

In most cases, resolving this alert only requires purchasing a replacement IMWF water filter, which typically costs in the range of $15 to $40 depending on the retailer and whether it is a genuine or compatible part. No tools or professional service are usually needed for a straightforward filter swap. If the issue persists after filter replacement and involves a component failure, diagnostic service costs would be additional.
