Error Code: F47 Difficulty: Hard
Problem: Water Filtration System Issue. The dishwasher’s water filtration system is not operating correctly.
How to Fix F47 Error (Step-by-Step)
- Disconnect the dishwasher from power and water. Turn off the circuit breaker for the dishwasher and shut off the water supply valve, usually located under the sink.
- Remove the lower dish rack to access the filter system at the bottom of the dishwasher tub.
- Twist the upper filter assembly counter-clockwise and lift it out. Then, pull out the lower filter that sits underneath it.
- Thoroughly clean both filters under running water. Use a soft brush to gently scrub away any food particles or debris. Do not use abrasive materials that could damage the filter mesh.
- While the filters are removed, inspect the filter housing and the sump area for any foreign objects or blockages. Carefully remove any debris you find.
- Inspect the drain hose for any kinks, clogs, or damage. Disconnect the hose from the dishwasher and the sink drain to check for obstructions. Clear any blockages you find.
- Reinstall the clean filters, ensuring they are securely locked in place. Reconnect the drain hose, restore power and water to the dishwasher, and run a short cycle to test the repair.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
