What the error code means

When the “IE” error code is displayed, it signifies that the washing machine is not able to properly fill with water, likely due to a problem with the water inlet system.  

Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind: 

• Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
• Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access the interior parts.
• Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
• Check your user manual to see if there are specific installation or safety instructions for your part or appliance. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
• Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
• If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it. 
• Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Turn off the water supply at the outlet before beginning repairs to any appliance parts that hold water. Have towels ready for any residual water in the system when removing parts. 

Troubleshooting steps

1. Disconnect power to the washer. 
2. Remove the top plate to access the interior parts by removing the 2 screws on the back. 
3. Push the top plate towards the back a few inches, then lift it off. 
4. Locate the water supply valves at the back of the washing machine. Verify that the hot and cold water supply valves are open to allow maximum water flow.
5. Check that the water supply lines that connect the valves to the washer’s water inlet ports. Look for any kinks, bends, or restrictions that could be preventing water from flowing freely. If the hoses are damaged, replace them with new fill hoses.
6. Remove the fill hoses from the inlet valves and check the small mesh screens for any debris or obstructions. The inlet valve filters can become clogged with mineral deposits over time.

Test the water inlet valve

LIVE VOLTAGE WARNING: For this test, the appliance needs to be plugged in and powered on. Please be very careful to protect yourself from electric shock, which has the potential to cause serious injuries. Don’t ever test live voltage if you’re uncomfortable using a multimeter.

1. With the washer unplugged, disconnect the inlet valve wiring and measure the resistance of the inlet valve coil. 
2. Use your multimeter to measure the resistance across the terminals or connectors of each water inlet valve. The expected resistance range is typically 0.8 to 1 ohm.
3. If the measured resistance is significantly higher or lower than the expected range, it indicates a problem with the inlet valve coil, and the valve will need to be replaced.
4. Set your multimeter to measure AC voltage and check for 120V AC at the inlet valve connectors when the washer is powered on and trying to fill.  
5. If you do not measure 120V AC, there may be an issue with the wiring or control board.

Verify wiring connections

1. Check all wiring connections at the water inlet valves, pressure switch, and the main control board.
2. Ensure the connectors are secure and free of corrosion.
3. If any wiring connections appear loose or damaged, reconnect or replace the wiring as needed.

Inspect the pressure switch and hose

1. Locate the pressure switch, which is usually connected to the washer tub by a small hose. The pressure switch is a safety device that monitors the water level in the washing machine tub and signals the control board when to start and stop the fill process.
2. Examine the small hose that connects the pressure switch to the washer tub, looking for any cracks, kinks, or obstructions that could be preventing proper pressure monitoring.
3. Verify that the pressure switch hose is tightly connected to both the pressure switch and the washer tub, with no loose fittings.
4. If the hose is damaged, replace it. 
5. Test the pressure switch by disconnecting the hose and blowing into it. The washer should start filling if the pressure switch is working correctly. 

If you’ve completed these troubleshooting steps and the washer still does not fill, there may be a problem with the control board
