- Open the water supply. Make sure the water supply faucets behind the washer are fully open.
- Check the fill hoses. Check the water fill lines for kinks and freezing.
- Check the water inlet valves. Check the water inlet valves.
- Do a power reset. Unplug the appliance or switch off its breaker for one minute, then restore power and try again. If the code clears and stays away, it may have been a one-off fault.
