Check the Float Switch
Locate the float switch, usually found at the bottom of the dishwasher, near the drain pump. Use a Phillips #2 screwdriver to remove the screws holding the float switch in place. Gently pull the float switch out and inspect it for any signs of damage or blockages. Check for any debris or food particles that may be preventing the float switch from functioning properly.

Check the Water Level Sensor
The water level sensor is usually located near the float switch. Use a multimeter to check the sensor's resistance. The sensor's resistance should be around 10-20 kΩ.
