Hisense Dishwasher Error Codes Explained!

Remember to always unplug the dishwasher and exercise caution when attempting any repairs.

F10: Overflow Error

The F10 error code stating that there is too much water inside the dishwasher typically means that the dishwasher’s water level has exceeded the normal limit. This could be due to various reasons, such as a malfunctioning water inlet valve, a faulty float switch, or a clogged drain. When the dishwasher detects an excessive amount of water, it triggers the error code to alert the user or technician that there is a water inlet issue.

Solutions:

  • Examine the wiring harness for any loose connections or damage.
  • Inspect the outlet hose for any blockages or kinks that may be obstructing the water flow.
  • Inspect the water inlet valve, which controls the water flow into the dishwasher. Make sure it is not clogged or stuck open. If you find any issues, such as debris blocking the valve or a faulty valve, consider cleaning or replacing it as necessary.
  • Check the flowmeter, which measures the amount of water entering the dishwasher, to ensure it is operating correctly.
  • Verify the functionality of the float switch, which detects water leaks and prevents flooding. Clean the switch and its surroundings if needed, or replace it if it’s faulty.
  • A clogged or blocked drain system can cause water to accumulate in the dishwasher. Check the drain hose, drain pump, and drain filter for any obstructions or debris. Clear any blockages you find.

F11: Water Outlet Error

When you encounter an F11 error code indicating that the drain pump is not effectively draining the water from the dishwasher, it suggests that there is a problem with the dishwasher’s drainage system. If the pump fails to function correctly, it can result in a water outlet error.

Solutions:

  • Examine the wiring harness for any loose connections or damage.
  • Inspect the hydraulic sump for any blockages that may hinder water drainage.
  • Inspect the drain filter, drain hose, and pump for any debris or blockages. Clear away any clogs or foreign objects that may hinder the flow of water. Ensure that the drain hose is not kinked or bent, as this can impede proper drainage.
  • Inspect the drain hose or siphon, as well as the filter, for any clogs that may be impeding water flow.
  • If applicable, clean the course filter to remove any debris or residue.
  • Ensure that the yellow locking plug is properly connected.
  • Manually verify if the drain pump is operating correctly.
  • Check the drain pump resistance using an ohmmeter.

  • If the above steps do not resolve the problem, replace the main board.

F12: Water Inlet Fault

This F12 error code indicates that there is an issue with the dishwasher’s water supply. The water inlet is responsible for allowing water to enter the dishwasher during the washing cycle. If the water inlet fails to function properly, it can result in insufficient water entering the dishwasher.

Solutions:

  • Ensure that the water supply to the dishwasher is turned on and that there is sufficient water pressure. Make sure that the water supply valve connected to the dishwasher is fully open and not restricted in any way.
    • Check the water pressure from the main supply and ensure it meets the dishwasher manufacturer’s requirements. If the water pressure is too low, you may need to contact a plumber to address the issue.
  • Check the water inlet hose for any kinks, bends, or damage that may be restricting water flow. Ensure that the hose is properly connected to both the dishwasher and the water supply valve.
  • Remove any debris or sediment that may be blocking the filter and affecting water flow. Clean the filter and reinstall it properly.
  • Check the water valve to ensure that it is not obstructed or malfunctioning.

  • Ensure that the flowmeter is functioning correctly and accurately, measuring the water flow.
  • If the error still occurs, check and replace the main board.

F40: Leakage on the Inlet Valve Error

This F40 error code signifies that the dishwasher has detected a leak in the area around the water inlet valve. If there is a leak, it can cause water to escape and trigger the error code.

Solutions:

  • Check the water inlet valve for any signs of leakage. Check the valve itself as well as the connections between the valve and the water supply hose. Look for visible signs of water dripping. If you notice any leaks, tighten the connections or replace the faulty valve.
  • Check the dishwasher tub and the gasket or seal around the door for any signs of water accumulation or leakage. Make sure that the door gasket is intact and properly seated. Clean or replace the gasket if it appears worn or damaged.
  • Ensure that the flowmeter is receiving 5 Vdc; if not, replace the main board.
  • Check the pressure sensor.
  • If the error code persists, replace the main board.

F41: Heating Error

This F41 error code indicates that there is an issue with the component responsible for heating the water during the dishwasher’s operation.

Solutions:

  • Check the wiring and connections associated with the heating element. Look for loose or damaged wires, burned connections, or any signs of electrical malfunction.
    • Ensure all connections are secure and free from damage. Repair or replace any faulty wiring or connections as needed.
  • Inspect the heating element for any visible signs of damage, such as cracks, breaks, etc.
  • Use a multimeter set to resistance or continuity mode to test the heating element. Disconnect the dishwasher from the power supply and access the heating element. Touch the multimeter probes to the terminals of the heating element, and the resistance should be around 12 ohms. If there is no reading, it indicates a faulty heating element that needs to be replaced.

F54: Float Switch Error

This F54 error code suggests that when the float switch detects water accumulating in the dishwasher’s base, it triggers an error code to indicate a potential leak.

Solutions:

  • Check all the hoses and connections in the dishwasher, including the inlet hose, drain hose, and any other hoses associated with the water supply or drainage. Look for signs of damage, loose connections, or leaks. Tighten connections or replace damaged hoses as necessary.
  • Check the dishwasher’s base for the presence of water or excessive moisture. If you find water in this area, it suggests a leak that has triggered the float switch. Identify the source of the leak, which could be a damaged hose, a loose connection, or a faulty door seal.
  • Check the door gasket and other seals within the dishwasher for any signs of wear, damage, or misalignment. A faulty seal or gasket can cause water to leak out during operation. Clean or replace the seal or gasket as needed.
  • If there is no visible water or moisture, clean the float switch and its surrounding area. Use a soft cloth to remove any debris or buildup that may be interfering with the proper operation of the float switch.
  • After cleaning, perform a test to ensure the float switch is functioning correctly. Gently lift the float by hand and observe whether it moves freely and triggers the switch. If the float switch does not activate or is not responsive, it may need to be replaced.
