Insufficient water supply: This is the most common cause of the FL error code. Make sure that the dishwasher is connected to a water supply with adequate pressure and flow. You can also try turning on a faucet in another part of the house to check for low water pressure.
Clogged inlet valve: The inlet valve is responsible for supplying water to the dishwasher. If the valve is clogged, it can prevent water from flowing into the appliance. You can check for clogs by disconnecting the inlet valve from the dishwasher and inspecting the screen.
Faulty float switch: The float switch is a sensor that detects the water level in the dishwasher. If the float switch is faulty, it can send an incorrect signal to the control board, causing the FL error code. You can check the float switch by disconnecting it from the control board and measuring its resistance with a multimeter. The resistance should be within the specified range for your dishwasher model.
Troubleshooting Steps:
Check the water supply: Make sure that the dishwasher is connected to a water supply with adequate pressure and flow. You can also try turning on a faucet in another part of the house to check for low water pressure.
Check for clogs in the inlet valve: Disconnect the inlet valve from the dishwasher and inspect the screen. If you see any clogs, remove them with a toothpick or other small, pointed object.
Check the float switch: Disconnect the float switch from the control board and measure its resistance with a multimeter. The resistance should be within the specified range for your dishwasher model. If the resistance is outside of the specified range, replace the float switch.
Additional Tips:
If you have checked all of the possible causes and the FL error code is still occurring, you may need to contact a qualified appliance repair technician.
You can also consult your dishwasher’s user manual for additional troubleshooting instructions.
Here are some additional details that you could include in your explanation:
The FL error code is usually accompanied by a message on the dishwasher’s display that says “Insufficient Water Level.”
The FL error code can prevent the dishwasher from completing the wash cycle, so it is important to address the issue as soon as possible.
If you are unable to resolve the FL error code on your own, you should contact a qualified appliance repair technician.
