Problem: Cold water inlet error – issue with cold water supply

How to Fix 4c Error

1. This is an error with the cold water supply. First, ensure the cold water faucet connected to the washer is turned on fully.
2. Check the cold water inlet hose for any kinks or twists that could block water flow.
3. Turn off the water, disconnect the hose from the back of the washer, and check the small filter screen inside the inlet port for debris. Clean it if necessary.
4. If the above steps don’t work, the cold water inlet valve has failed. Unplug the washer, replace the valve assembly, and reconnect the hoses and wiring.

Problem: Leak detected (front-load) OR gear/auto-restart error (top-load) – meaning varies by washer type

How to Fix AE Error

1. The meaning of this code depends on your washer type. Unplug the washer first.
2. For FRONT-LOAD washers, it’s a leak error. Check the drain pump filter for a loose cap. Inspect all hoses for visible leaks. If no leak is found, the leak sensor at the base of the machine may be faulty or has detected a small internal drip.
3. For TOP-LOAD washers, it’s a gear/clutch error. This indicates a mechanical failure in the drive system and typically requires replacement of the clutch assembly, which is a major repair.

Problem: Over-current error in motor electrical circuit – caused by short circuit, loose connection, or power surge

How to Fix CE Error

1. This error indicates a dangerous over-current in the motor circuit. Unplug the washer immediately.
2. Access the motor at the bottom or rear of the machine.
3. Carefully inspect the motor wiring harness for any pinched, frayed, or shorted wires. Check that the connection is secure.
4. If the wiring looks good, the motor stator may have a short circuit and needs to be replaced.
5. In rare cases, the main control board could be causing the error. This is usually the last part to replace if the wiring and motor are good.

Problem: Child Lock active – control panel is disabled; not an error code

How to Fix CL Error

1. This is not an error. ‘CL’ means Child Lock is active, which disables the control panel buttons.
2. To turn it off, press and hold the ‘Child Lock’ button for 3 seconds. The button is often marked with a small smiley face or lock icon, and may require pressing a combination of two buttons simultaneously.

Problem: Cool Down – drying cycle complete; periodic tumbling to prevent wrinkles

How to Fix Cd Error

1. This is not an error. ‘Cd’ stands for ‘Cool Down’ and appears after a drying cycle is complete on washer/dryer combo units.
2. The washer will periodically tumble the clothes without heat to prevent wrinkles from setting in.
3. You can remove the clothes at any time by pressing the power button.

Problem: Overflow error – alias of FE on newer models

How to Fix E12 Error

1. This is an overflow error. Unplug the washer and shut off the water supply immediately.
2. Manually drain the washer using the emergency drain hose, usually located behind a small access panel on the bottom front.
3. Check the pressure sensor air tube for clogs or kinks. If the tube is clear, the pressure sensor itself may be faulty. Replace it.
4. If the problem continues after replacing the sensor, the water inlet valve is likely stuck open and needs to be replaced.

Problem: Heater error – temporary heating element malfunction

How to Fix HE Error

1. Disconnect the washer from power at the circuit breaker. This involves working with heating components.
2. Access the heater assembly, usually from the bottom front or rear of the washer.
3. First, test the thermistor (temperature sensor) on the heater assembly for resistance (typically around 12,000-30,000 ohms at room temp, but check your model’s specs). If it fails, replace it.
4. If the thermistor is good, test the heating element itself for continuity. An open circuit (infinite ohms) means the element is burned out and the entire heater assembly needs replacement.
5. Replace the faulty component, reassemble, and check for leaks before restoring power.

Problem: Locked motor with possible water level sensing error – motor obstruction on top-load models

How to Fix LE1 Error

1. Unplug the washer. This error on a top-load model often indicates something is jamming the motor or clutch.
2. Check for any small items that may have gotten between the inner and outer tubs.
3. If nothing is found, the issue is likely a faulty Hall Sensor or a failed clutch assembly. This is a major repair requiring removal of the rotor and stator to access the components.
4. Test the Hall Sensor for proper readings. If it’s faulty, replace it.
5. If the sensor is good, the clutch assembly has likely failed and needs to be replaced.

Problem: Water level pressure sensor malfunction – sensor unable to detect water level correctly

How to Fix PE Error

1. Unplug the washer.
2. Locate the water level pressure sensor, typically in the top part of the machine with a thin air tube attached.
3. Disconnect the air tube from the sensor and blow gently into it to clear any potential blockages in the tube.
4. Inspect the tube for any cracks, holes, or loose connections at the tub end.
5. If the tube is clear and intact, the pressure sensor has failed and needs to be replaced.

Problem: Sensor error – motor sensor (hall sensor) malfunction

How to Fix SE Error

1. Disconnect the washer from power. This error points to a faulty motor Hall Sensor.
2. You will need to access the motor at the back or bottom of the washer. Remove the rear service panel.
3. Remove the large central bolt holding the rotor to the drive shaft. Pull the rotor off.
4. The stator (the part with copper windings) is now exposed. The Hall Sensor is a small component mounted on it. Disconnect the wire harnesses.
5. Unbolt the stator, and replace the Hall Sensor (or the entire stator assembly).
6. Reassemble in reverse order.
