GE Profile UltraFast Combination Washer / Dryer Confirm H2O Supply is ON Error Code
What it means
GE says H2O SUPPLY means water is not entering the UltraFast Combo.
Try this first
- Check the water-supply hose and make sure at least one supply valve is on.
- For an approved sink connection, verify the faucet/Y-splitter arrangement is open.
- Allow the 4-minute lockout to finish before restarting; unplugging restarts the timer.
