What should I do if the washer displays the 'HC' error code?

The 'HC' code appears at the end of the wash cycle to indicate that the cold and hot water inlet hoses are switched. Check and reconnect the hoses so that the hot water hose is attached to the hot water inlet valve and the cold water hose is attached to the cold water inlet valve. If an error code does not appear but you are experiencing poor washing performance, also check whether the inlet hoses may be reversed. (Page 19)
