How to Fix WATER TAP SYMBOL Error (Step-by-Step)

  1. 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.
  2. 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.
  3. Gently straighten any part of the hose that is pinched or bent.
  4. Turn off the water supply valve. Place a small bucket or towel under the connection and unscrew the hose from the valve.
  5. Look inside the end of the hose for a small filter screen. Check if it is clogged with sediment or debris.
  6. Remove the screen with needle-nose pliers if possible and rinse it thoroughly under running water until clean. Re-insert the filter.
  7. Securely reattach the hose to the water supply valve, turn the water back on, and start a new cycle to clear the error.
  8. Turn the appliance off, wait about 2 minutes, then turn it back on.
