haier | dishwasher – Overflow Error – Too Much Water Inside
Error Codes (FE): Troubleshooting, Fixes & Prevention Tips explained below.

What Does Overflow Error Mean❓

The Overflow Error indicates that the dishwasher has filled with more water than it is designed to handle. This condition is usually detected by a float switch or water level sensor, which triggers the error to prevent flooding. It may occur due to a faulty inlet valve, blocked drainage, or a malfunctioning float switch. The dishwasher may stop mid-cycle and refuse to start again until the issue is resolved. In severe cases, water may leak from the door or bottom of the unit.

dishwasher - Common Causes of Overflow Error

  • Malfunctioning or stuck water inlet valve allowing continuous water flow.
  • Blocked or slow-draining outlet causing backup.
  • Faulty or jammed float switch failing to detect water level.
  • Incorrect detergent causing excessive suds and overflow.
  • Software or control board malfunction mismanaging the fill cycle.

dishwasher - Steps to Fix Overflow Error❓

  • Turn Off Power and Water Supply

    1. Unplug the dishwasher and shut off the water valve to stop further water flow.
    2. Allow the unit to cool before inspecting.

  • Remove Excess Water Manually

    1. Open the door and use a sponge or towel to soak up standing water.
    2. Ensure the base tray is also dry to avoid additional errors.

  • Inspect the Inlet Valve

    1. Check if the water inlet valve is stuck open or leaking.
    2. Replace it if it does not shut off properly.

  • Test the Float Switch

    1. Lift the float inside the tub to ensure it moves freely.
    2. If stuck or faulty, the float switch may need cleaning or replacement.

dishwasher - Helpful Tips to Prevent Overflow

  • Use only recommended dishwasher detergents in the proper amount.
  • Ensure the drain is not clogged and water flows freely.
  • Clean the float switch area regularly to prevent jamming.
  • Check hoses and valves during routine maintenance.
  • Avoid pausing cycles mid-fill without draining first.
