- Check Wire Harness: Inspect the wire connections to the wash pump motor for looseness or damage.
- Check for Blockages: Ensure there are no foreign objects obstructing the wash pump impeller.
- Thermal Fuse: The wash pump has a thermal fuse that trips at 284∘F. You can check its resistance with a multimeter. It should be around 0.1−2 Ω. An open circuit (∞ Ω or OL) indicates a blown fuse.
- Electric part name: Pump thermal fuse
- Temperature: 274∘F±10∘F
- Ohmic value: ∼0.1−2 Ω
- Abnormal value: ∞ Ω | OL

Solution:
- Unplug and Inspect: Immediately unplug the dishwasher. Carefully inspect the area around and beneath the dishwasher to locate the source of the leak.
- Repair Leak: Once the leak is found, the source of the water intrusion must be repaired. This could be a faulty hose, seal, pump, or other component. Note: This error often requires professional service to identify and fix the leak correctly.
Turbidity Sensor Error (Codes 550147, 550196)
The turbidity sensor measures how dirty the water is during the cycle and helps the dishwasher optimize wash performance.
- 550147, 550196: Turbidity sensor error.
Solutions:
- Power Cycle and Reset: Unplug the dishwasher for 60 seconds. Plug it back in and attempt to use the “Reset All” function. See if the error persists.
- Harness Connections: Check that the wire harness connected to the turbidity sensor is secure.
- Clean Sensor: The sensor can become coated with debris. Locate the turbidity sensor (usually in the sump area) and gently clean it according to your owner’s manual.
- Replace Sensor: If cleaning doesn’t help, the turbidity sensor may need to be replaced.
- Main Board: In rare cases, the main board could be the cause.
Water Softener and Salt Errors (Codes starting with 5701)
These errors relate to the built-in water softener system.
- 570114: Low salt in water regeneration tank error.
- 570154: Low rinse aid error.
Solutions for 570114 (Low Salt):
