Error Code: F12 Difficulty: Hard
Problem: Water intake fault at the start of a cycle, with no pulses detected from the flow meter.
How to Fix F12 Error (Step-by-Step)
- Turn off the power to the dishwasher at the circuit breaker and shut off the water supply valve, which is typically located under the sink.
- Carefully pull the dishwasher out from under the counter to access the water connections. Place a towel underneath the water inlet hose connection to catch any residual water.
- Inspect the water inlet hose for any kinks or sharp bends that could be restricting water flow. Straighten the hose if necessary.
- Disconnect the water inlet hose from the dishwasher. Check the small filter screen inside the inlet valve for any debris or sediment buildup and clean it thoroughly with a small brush under running water.
- If the hose and filter are clear, the water inlet valve and flow meter assembly is likely faulty. This part is usually located on the left side of the dishwasher base. Disconnect the wiring harness and hoses attached to the old valve.
- Install the new water inlet valve assembly, ensuring all hose clamps and electrical connectors are securely fastened in the same positions as the original part.
- Reconnect the main water supply hose, slide the dishwasher back into place, turn the water supply and circuit breaker back on, and run a test cycle to ensure the error is resolved.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
