LG Dishwasher IE (1E) Error Code: Not Filling With Water (Meaning, Causes, Fixes)

Reviewed 2026-10-24 · Based on 4 manufacturer & service sources

What the code means

LG calls IE a Water Inlet Error. While washing, the dishwasher fills, sprays and drains several times, and IE appears when the specified amount of water isn't supplied to the tub. LG's help article says the error means the water level is still too low (insufficient water) after 30 seconds to 10 minutes of filling. You may also hear the dishwasher chime while no water comes in. LG separates IE from E1, which is a different error.

Likely causes

Safe DIY checks

⚠ Before you start

Unplug the appliance (or switch off its breaker) and shut off the water supply valves before removing panels or disconnecting hoses. Keep towels handy for residual water.

  1. Turn on the kitchen and bathroom faucets. If no water comes out anywhere, the house supply is off and the dishwasher can't fill until it's restored.
  2. Open the cabinet under the sink and find the supply line going to the dishwasher. Move anything pressing on it and straighten any kinks or sharp bends. Replace the hose if it's torn.
  3. If the dishwasher was just installed or moved, turn the water supply valve for the dishwasher counterclockwise to open it fully. LG also says to check that the water pipe valve above it is open.
  4. Clean the inlet filter: unplug the dishwasher and turn off the water valve, unscrew the supply hose, remove the seal and plastic filter with small pliers, and clean the filter under running water with a soft brush. Refit the filter and seal so they sit correctly and are free of grit, then hand-tighten the hose. LG says not to use a tool to tighten it.
  5. Turn the water back on and check the connection for leaks, then plug the dishwasher back in.
  6. Make sure the home's water pressure is between 20 and 80 psi. Low pressure can stop the tub from filling in time.
  7. Start a cycle and listen for water coming in. If IE returns while your faucets have normal flow, request LG service.

🛠 When to call a pro

  • IE keeps coming back even though the valve is open, the hose is straight, the inlet filter is clean, and pressure is in range. LG says a professional inspection is required.
  • The dishwasher was just installed and still won't fill after you open both valves. LG says to contact the technician who installed it.
  • The supply line or its fitting leaks after you reconnect it.
  • Your home's water pressure is below 20 psi, which is a plumbing problem rather than a dishwasher fault.
  • You hear no fill sound at all with the valves open, which LG says can mean a faulty inlet valve that needs service.
