Below are some of the typical error codes displayed by a Hisense dishwasher.
Hisense Dishwasher Error Codes
F10: Water Inlet Error
When the dishwasher displays the F10 error, it usually signifies that the water level has risen above the recommended maximum. This may result from a blocked drain, a broken float switch, or a damaged water entry valve. Dishwashers set off this error code when they detect an overflow of water, which indicates an issue with the water supply.
To fix the F10 error code, disconnect the dishwasher and go ahead to:
● Inspect for any damage or loosened connections in the wire harness.
● Check out the water supply’s entry point, and if you encounter problems, such as debris blocking the valve or a broken valve, clean or replace it.
● Ensure the dishwasher receives the proper amount of water by testing the flowmeter.
● Ensure the float switch is working properly to avoid any water leaks before they cause flooding. You should clean or replace the switch if it is dirty or broken.
● Examine the drain pipe, pump, and filter for dirt or clogs. Get rid of the obstacles you find.
F11: Water Outlet Error
When an F11 error message appears, the dishwasher’s drain pump is not removing water quickly enough. There is a problem with the dishwasher’s drainage system, which a faulty water pump could trigger.
To fix the F11 error code, check the hydraulic sump, drain filter, and drain hose for obstructions that could prevent water from draining properly. There may be obstructions or foreign objects that could cause water flow problems; hence, remove them.
Consider using an ohmmeter to test the drain pump’s resistance. Ohmic readings between 0.1 Ω and 1.0 Ω | OL / Ω, which is abnormal, while the usual range is 34 Ω 120V ac | 190 Ω 220 Vac.
Also, ensure the yellow locking plug is correctly connected. If those troubleshooting methods don’t work, consider swapping out the motherboard.
F12: Water Inlet Fault
The F12 error code means a problem with your dishwasher’s water supply. The water inlet lets water into the dishwasher for the cleaning cycle. In the event of a malfunctioning water inlet, there is a potential for inadequate water intake into the dishwasher.
To fix the F12 error code:
- Ensure your dishwasher has enough water pressure, as low water pressure indicates that you might need to call a plumber.
- Ensure no kinks, bends, or leaks in the water inlet hose.
- Check that the dishwasher and the faucet valve receive water through the hose.
Furthermore, clear the filter of any silt or debris obstructing water flow. Remove the filter, clean it, and if it’s too faulty, replace it to allow proper water flow.
F40: Leakage on the Inlet Valve Error
The F40 error code indicates your dishwasher leaks near the water inlet valve.
In this case, you must examine the water inlet valve for any dripping. Check for water dripping, and if there are any leaks, try tightening the screws or swap the broken valve.
Inspect the dishwasher for water gathering in the tub and a leaking gasket or barrier around the door. If it seems dirty or damaged, clean it or replace it. Lastly, verify the flowmeter is getting 5Vdc power; swap out the circuit board if it isn’t. Also, ensure the pressure gauge is functioning properly. If the F40 error persists, reinstall the motherboard.
F41: Heating Error
The F41 error number signifies a malfunction in the heating component of your dishwasher, which is responsible for raising the water temperature during its operational cycle.
To solve this issue:
- Start by inspecting that the heating element is properly wired and connected.
- Check for symptoms of electrical problems such as burnt connections and frayed wires.
- Tighten the cables and fix or replace them if they have cracks or breaks.
Check the heating element using a multimeter in the resistance or continuity mode. If you place the probes of a multimeter on the terminals of the heater, you should read a resistance of about 12 ohms. If there’s no reading in the heating element, replace it.
F42: Temperature Sensor Error
If your dishwasher displays the F42 error, it probably sensed a temperature that was too high or too low. Conduct a thorough examination of the wiring harness to identify any loose connections or physical impairment.
Test the dishwasher’s temperature sensor to ensure it gives you an accurate reading. The electric component referred to as the NTC sensor possesses an ohmic value of 10 KΩ at a temperature of 25 °C (77°F). If none work, contact a professional or swap out the motherboard.
F43: Pressure Sensor Error
The F43 error code on your dishwasher’s display means the pressure sensor is malfunctioning.
If this error persists, you need to examine the wiring for any frayed or disconnected segments or other damage that could be causing the F43 error.
The proper functioning of the pressure sensor is crucial for precisely sensing the pressure within the dishwasher. If the fault persists, check the control unit and replace it, or hire a professional to rectify the pressure sensor error.
F44: Turbidity Sensor Error
The F44 code indicates that your dishwasher’s mechanism for measuring the amount of dirt and food particles in the water has malfunctioned. The dishwasher’s turbidity sensor aids in calculating how much water and detergent your dishwasher requires for an automatic cycle.
Confirm that the turbidity sensor’s wiring and connections are working well. Check for symptoms of electrical malfunction, such as frayed or exposed wires, and fix or replace the damaged ones.
When the turbidity sensor gets filthy or covered in residue, it stops working properly. Remove any gunk blocking it with a damp cloth. Search for rust or other physical damage on the turbidity sensor and replace it if necessary.
Furthermore, you must install the turbidity sensor in the dishwasher in a straight, level position.
F45: Diverter Valve Error
If your dishwasher displays the F45 error, there’s a problem with the part controlling the water flow inside the appliance.
The diverter valve directs the water flow to various components, such as the lower, middle, and upper spray arms. Therefore, there shouldn’t be any fractures, leaks, or obstructions to the diverter valve’s movement. If a problem arises, you should replace the diverter valve. Also, you can test the micro-motor resistance with a multimeter. It will be necessary to replace the diverter valve if it does not pass inspection.
F52& F53: Water Level Errors
The F52 and F53 error codes indicate an issue with the dishwasher’s water level. Check that the pressure sensor detects the dishwasher’s water level correctly and that the valve releases the right amount of water. Also, the flowmeter should accurately record the quantity of water used.
Check the drain hose and air brake mechanism to ensure they work properly. Also, check for frayed or broken spots in the wiring harness. Additionally, ensure that the drain pump works properly by emptying some water and cleaning the filter of any debris or residue that may have accumulated.
F54: Float Switch Error
The F54 error code indicates that the dishwasher may leak because the float switch has detected water collecting in the dishwasher’s base.
Examine hoses for wear and tear, slack connections, and leaks; repair or replace as necessary. Check for dampness or water in the dishwasher’s bottom. You should inspect gaskets and seals on your dishwasher doors for wear, corrosion, and improper alignment. Keep the seal and gasket in good condition by cleaning or replacing them as required.
If there’s no water, check the float switch and its surroundings for debris and clean them if necessary. Activate the button by lifting the float by hand to observe if it moves freely. You might need a new one if the float switch doesn’t work.
F56: Circulation Pump Error
The F56 error number signifies a failure in the circulation pump of the dishwasher. You should inspect the wiring harness for potential loose connections or physical damage. Also, check that the pump in charge of circulation is working properly.
Hisense Dishwasher Troubleshooting
Some typical issues can arise when using a Hisense dishwasher. This section provides in-depth advice for handling these concerns.
The Door Will Not Close
There could be an issue with the arrangement of the baskets. Ensure the baskets are horizontally aligned and that the dishes are not in the way of the baskets’ ability to slide into place.
The Dishwasher Will Not Start
This can happen if you do not hook your dishwasher’s power cord into the wall outlet, the fuse or circuit breaker has tripped, or both. Also, make sure there is no leakage or overflowing water by checking the supply valve.
The Dishes Are Still Dirty
This suggests that the spray arms are stuck and must be removed and cleaned. Use the right detergent and soft brushes, and replace the filters when completely worn out.
