A reminder, not a fault
On a bottom-freezer Whirlpool refrigerator the H2O light does not report a malfunction. It reminds you about the water filter. Product Help sets the replacement points at six months, a lit indicator, or whenever the situation calls for it.
Why it may be sooner
Usage and water quality both matter, so a filter may need changing more often than twice a year. A clogged filter, or one that was seated badly, can restrict the water reaching the ice maker as well as the dispenser. Expect thin ice output and a weaker stream.
Clearing the light
Install the new filter.
Press and keep pressing LIGHT together with ICE TYPE for 3 seconds.
When the reset registers, the status light switches off.
FEE3: a flashing F code that begins its steps at the water supply.

Plain language
What this code means
The H2O light is a water filter indicator that comes on when the filter should be replaced.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
