Most manufacturers advocate for changing the water filter in your refrigerator once every six months. If, however, your refrigerator water dispenser gets more use than the average, then it may need to be changed sooner than the recommended six months.
Depending on the usage, sediments, and if there is a strong taste or smell coming from the water being dispensed, you will be able to determine if it’s time for a new water filter. If you continue to use your water filter after it has reached its expiration, you could be at risk for bacteria and mold contaminants in your water.
Other indications that it’s time for a new filter include; your ice maker has stopped producing ice, the water flowing from your dispenser has slowed down, and your status indicator light is on. Your status indicator light is set to turn on every six months every time it is reset; it signifies it’s time to replace your filter. After you have changed your filter it is important that you reset your indicator light manually, you can refer to your refrigerator manual if you do not know how.
If you are experiencing any of these symptoms with the water coming from your refrigerator, then you should stop drinking the water immediately until after the filter is replaced.
