What Does Error E12 Mean?
The Sharp Washing Machine E12 error code indicates a drainage issue caused by high inlet water temperature during filling, often resulting in the machine stopping operation with a water level warning displayed. This typically occurs when the water temperature exceeds the recommended threshold of approximately 44–50°C, leading to a malfunction in the washer's operation. To resolve this, it's essential to check and adjust the water source temperature.
Common Symptoms:
- Error E12 displayed on the machine panel during water fill.
- Machine stops operation shortly after start due to water temperature issue.
Possible Causes
- High inlet water temperature during fill (high)
How to Fix Error E12
DIY Fix Check and Adjust Water Source Temperature
- Turn off the washing machine.
- Check if the water supply connected to the washer includes hot water from a water heater.
- If so, adjust the water heater or inlet settings to ensure the temperature is below approximately 44–50°C as per Sharp documentation.
- Switch to cold water inlet only if possible.
- Power on the washing machine and start a new cycle.
Technician Only Inspect Water Inlet System and Sensors
- Confirm proper installation of water inlet hoses, ensuring cold water supply is correctly connected.
- Check temperature sensor (NTC) and associated wiring in the inlet path for damage or incorrect readings.
- Verify the hot/cold inlet valve operation to ensure it is not mixing hot water unexpectedly.
- Replace any faulty temperature sensors or inlet valves as required.
Parts needed: Water inlet valve assembly, Temperature (NTC) sensor, Inlet hose(s)
- If adjusting the inlet water source temperature does not clear the E12 error and the machine continues to display it on cold-only supply.
- If there are signs of faulty temperature sensing or inlet valve malfunction.
