1. Make sure no hose is kinked, pinched or crushed behind or under the washer. Take care when moving the washer for cleaning or maintenance.
The water inlet filters are clogged. Source: Troubleshooting: Error Messages, p. 48
1. Clean the water inlet filters. See Clean the water inlet filters.
The water pressure at the faucet or in the house is too low. Source: Troubleshooting: Error Messages, p. 48
1. Run another faucet in the house to check that pressure and flow are adequate.
2. Disconnect the inlet hoses from the washer and run a few gallons of water through them to flush out dirt.
Licensed plumber If the flow is still too low, have a plumber repair the supply lines.
The supply is connected with leak-limiting hoses. Source: Troubleshooting: Error Messages, p. 48
1. Do not use leak-limiting hoses; LG does not recommend them because they can trip falsely and prevent the washer from filling.
