LG dishwasher — Error Code IE
Inlet Error: The appliance is not receiving enough water to function.
What it means
The IE (Inlet Error) alert on your LG dishwasher signifies that the machine failed to reach the required water level within the typical 10-minute fill window. Your dishwasher uses a flow meter and a float switch (or pressure sensor) to track water levels. If the control board detects too few pulses from the flow meter or if the float switch remains inactive, it stops the cycle and pumps out any existing water to prevent the wash motor from running dry or the heating element from burning out. This is a vital safety feature. Usually, this error points to a restriction in the water supply, a broken solenoid valve, or a faulty sensor signal.
Likely Causes
- 1 Restricted or Shut-Off Water SupplyThis is a frequent issue. Check if the shut-off valve under your kitchen sink is fully open or if the braided stainless steel supply line has become pinched behind the dishwasher unit.
- 2 Blocked Inlet Valve ScreenMineral deposits from hard water—common in areas like Spokane—or sediment from recent plumbing repairs can clog the fine mesh screen inside the water inlet valve, preventing proper flow.
- 3 Malfunctioning Water Inlet ValveThe solenoid coil inside the valve can experience an electrical open circuit or get stuck mechanically. Even if the control board sends 120VAC to the valve, it will remain shut, blocking water entry.
- 4 Failed Flow Meter or Float SwitchIf the tub is filling but the IE error persists, the flow meter (case sensor assembly) or float switch is likely failing to send the correct water-level data to the control board.
- 5 Main Control Board or Wiring IssuesDamaged wiring or a fried relay on the main PCB may prevent the necessary voltage from reaching the inlet valve solenoid.
How to clear / reset
To reset the IE error temporarily, hit the Power button to turn off the dishwasher, then flip the circuit breaker for 10 to 15 minutes to clear the control board's memory. Before turning the power back on, verify your water supply valve is fully open and the inlet hose is free of kinks. Please note that if the problem is a faulty valve, debris, or a bad sensor, the IE code will return as soon as the machine attempts to fill again.
Common replacement parts
When to call a pro
If you have confirmed the water supply is open and the hose is straight, but the IE code remains, you should call a professional. Diagnosing the water inlet valve requires using a multimeter to check for 120VAC during the fill cycle, which involves working with live electricity. If the valve has power but no water flows, it is faulty; if there is no power, you must test the wiring or the control board. Contact A-Fix Service at (800) 200-2349. We charge a $90 diagnostic fee (waived if you proceed with the repair) and include a 1-year warranty on all parts and labor.
FAQs
What is the typical cost for an LG dishwasher IE repair?
If the issue is simply a kinked hose or a closed valve, it costs nothing to fix yourself. For professional replacement of a water inlet valve, expect costs between $150 and $250, covering both parts and labor.
Is it safe to run the dishwasher while the IE code is showing?
No. The machine is programmed to stop and drain to prevent the wash motor from operating without water. You cannot bypass this safety protocol.
Will the IE code go away on its own?
Power cycling the unit will clear the screen, but the error will immediately reappear on the next cycle if the dishwasher cannot take in enough water.
Can I clean the inlet valve screen on my own?
Yes, provided you are comfortable shutting off the water, removing the supply line, and using needle-nose pliers to pull out and clean the mesh screen. Be careful not to damage the mesh.
How long does a technician take to perform this repair?
For a skilled technician, replacing the flow meter or water inlet valve on an LG dishwasher usually takes between 30 and 45 minutes once the unit is accessed.
