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 the circuit breaker and shut off the water supply valve, which is typically located under the sink.
- Check the water supply hose for any kinks or bends that could be restricting water flow. Straighten the hose if necessary.
- Disconnect the water supply hose from the dishwasher’s inlet valve. Place a towel underneath to catch any residual water. Check the small filter screen inside the inlet valve for any debris or sediment and clean it with a small brush if it’s clogged.
- If the hose and filter are clear, the water inlet valve is likely faulty. To replace it, first remove the bottom front access panel (kick plate) of the dishwasher, which is usually held by two screws.
- Locate the water inlet valve, typically on the front left side. Disconnect the two wires attached to the valve, the main water supply line, and the hose that leads into the dishwasher tub. You may need pliers to loosen the hose clamp.
- Install the new water inlet valve by connecting the wires, the water supply line, and the internal hose in the reverse order you removed them. Ensure all connections are secure to prevent leaks.
- Re-install the front access panel, turn the water supply back on, and restore power at the circuit breaker. Run a short wash cycle to test the dishwasher and check for any leaks around the new valve.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
