LG high efficiency front and top load washers do not need a lot of hot water to operate normally. The machines are designed to be efficient and provide the cleaning power you expect while keeping energy consumption low. However, if you are sure that your unit is not filling with enough hot water, follow the troubleshooting steps below:
Inspect the hot and cold water hoses.
Inspect the inlet hoses to be sure that the hot and cold lines are not reversed.
Check if the inlet hoses are kinked, punctured, or have visible traces of leaks around them.
NOTE: On most washers, the hot water valve is always indicated by a RED ring around the knob. The hose may be marked with letters "H" for HOT and "C" for Cold.
Inspect the water taps.
Inspect the hot and cold water supply valves and make sure they are fully opened.
NOTE: The distance between your washing machine and the home’s hot water heater can be a factor. When the two are far apart, you can open the hot faucet at a sink nearby to the washer and purge out cold water from the lines prior to starting your wash cycle.
Use an alternate wash cycle.
The cycle that is selected dictates how much hot water will be used during the fill portion of the wash cycle. Cycles such as Sanitary, Allergiene™, and Bright Whites are designed to use more hot water.
NOTE: Your washing machine is capable of compensating for low water temperature with 6Motion™ Wash Technology. Different cycles use different wash motions to achieve warm water cleaning performance in cooler water temperatures.
