Error Code: WATER TAP SYMBOL Difficulty: Hard
Problem: Problem with the water supply.
How to Fix WATER TAP SYMBOL Error (Step-by-Step)
- Turn off the power to the dishwasher at your circuit breaker and shut off the water supply valve, which is usually located under the sink.
- Check the water supply hose for any kinks or sharp bends that could be restricting water flow. Straighten the hose if necessary.
- Unscrew the water supply hose from the dishwasher’s water inlet valve. Place a towel underneath to catch any residual water. Check the small filter screen inside the valve for any debris or sediment and clean it with a small brush and water.
- If the filter is clean and the hose is not kinked, the water inlet valve itself may be faulty. This part is located at the front, typically behind the bottom kick plate.
- To replace the valve, disconnect the power clip and the water supply line. Remove the two screws holding it in place. Install the new valve by securing it with the screws, reattaching the water line, and plugging in the power clip.
- If replacing the inlet valve does not solve the issue, the problem could be with the main water inlet assembly, which is a more complex component inside the dishwasher.
- After performing the repairs, reconnect the main water supply hose, turn the water and power back on, and run a test cycle to ensure the dishwasher fills with water correctly.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
