Error Code: WATER TAP SYMBOL Difficulty: Easy
Problem: Problem with the water supply.
How to Fix WATER TAP SYMBOL Error (Step-by-Step)
- Begin by checking the water supply valve connected to the dishwasher, typically located under your kitchen sink. Ensure the handle is turned fully counter-clockwise to the ‘on’ position.
- Pull the dishwasher out slightly from the cabinet to inspect the water inlet hose for any kinks or sharp bends that could restrict water flow.
- Gently straighten any part of the hose that is pinched or bent.
- Turn off the water supply valve. Place a small bucket or towel under the connection and unscrew the hose from the valve.
- Look inside the end of the hose for a small filter screen. Check if it is clogged with sediment or debris.
- Remove the screen with needle-nose pliers if possible and rinse it thoroughly under running water until clean. Re-insert the filter.
- Securely reattach the hose to the water supply valve, turn the water back on, and start a new cycle to clear the error.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
