The F12 error code on your Hisense dishwasher indicates a problem with the water supply. This means the dishwasher isn’t getting enough water to complete a wash cycle.
Let’s go through some steps to diagnose and fix the issue:
Troubleshooting Steps for the Hisense Dishwasher F12 Error Code
1. Check the water supply
- Turn on the water valve. Make sure the valve supplying water to the dishwasher is fully open.
- Water pressure: Check if the water pressure from your main supply meets the dishwasher’s requirements (refer to your user manual). If the pressure is low, contact a plumber.
2. Inspect the water inlet hose.
- Kinks or damage: Look for any bends or damage in the hose that might restrict water flow. Ensure the hose is securely connected to both the dishwasher and the water supply valve.
3. Clean the water inlet filter.
- Clogged filter: Debris or sediment can clog the filter, reducing water flow. Locate the filter (refer to your user manual) and clean it thoroughly. Reinstall the filter properly.
4. Check the water inlet valve.
- Malfunctioning valve: In some cases, the water inlet valve itself might be malfunctioning. If you’re comfortable with DIY repairs, you can use a multimeter to check the valve’s resistance. The resistance should be within the range specified (usually around 0.9 kΩ for 120V or 4 kΩ for 220V). If the reading is outside the range, the valve might need replacement.
5. Flowmeter malfunction:
- A flowmeter measures water intake. If the flowmeter malfunctions, it could lead to the F12 error. Refer to your repair manual or consult a technician for troubleshooting the flowmeter.
6. Main Control Board (last resort):
- Reset: If none of the above solutions work, try resetting the dishwasher by unplugging it for a few minutes and then plugging it back in.
- Replacement: In rare cases, the error might be due to a faulty main control board. If you’ve exhausted all other options, consider contacting a qualified appliance repair person for diagnosis and possible replacement.
By following these troubleshooting steps, you should be able to identify and fix the cause of the F12 error code on your Hisense dishwasher. For most users, the issue will likely be resolved by checking the water supply, inspecting the hose, or cleaning the inlet valve filter.
