Error Code: DRYING SYMBOL Difficulty: Easy

Problem: Indicates that the dishwasher is in the drying phase of the wash cycle.

How to Fix DRYING SYMBOL Error (Step-by-Step)

1. Identify the ‘Drying’ symbol on your dishwasher’s display, which often looks like rays of sun or heat waves.
2. Understand that this is a normal operational light indicating the dishwasher has finished washing and is now in the drying portion of its cycle.
3. This symbol is not an error and requires no action from you.
4. The dishwasher may use a heating element or condensation drying. The door may be hot to the touch if a heating element is active.
5. Allow the dishwasher to complete the drying cycle for the best results. Opening the door early can result in wet dishes.
6. The light will turn off, and the dishwasher will typically signal with a beep, once the entire cycle is complete.
7. Turn the appliance off, wait about 2 minutes, then turn it back on.

Error Code: DELAY START SYMBOL Difficulty: Easy

Problem: Allows the user to set a delayed start time for a wash cycle.

How to Fix DELAY START SYMBOL Error (Step-by-Step)

1. Recognize that the ‘Delay Start’ symbol (often a clock icon) means a wash cycle has been programmed to start at a later time. This is a feature, not an error.

5. This action should cancel the ‘Delay Start’ setting and reset the dishwasher. The ‘Delay Start’ symbol should disappear from the display.

7. Turn the appliance off, wait about 2 minutes, then turn it back on.

Error Code: CHILD LOCK SYMBOL Difficulty: Easy

Problem: Indicates that the child lock feature is activated, preventing accidental operation.

How to Fix CHILD LOCK SYMBOL Error (Step-by-Step)

1. Locate the ‘Child Lock’ symbol on your dishwasher’s control panel. This indicates the controls are locked to prevent accidental operation.
2. To deactivate the child lock, look for a button or text on the control panel specifically for this function. It is often labeled with a ‘key’ symbol or text like ‘Child Lock’.
3. Press and hold the designated ‘Child Lock’ button for approximately 3 to 5 seconds.
4. Watch for the ‘Child Lock’ symbol on the display to turn off, or listen for a beep confirming the deactivation.
5. Once the light is off, the dishwasher controls will be unlocked, and you can now select a cycle and start the machine as usual.
6. To reactivate the child lock, simply press and hold the same button again for 3-5 seconds until the indicator light reappears.

Error Code: CHECK WATER LIGHT Difficulty: Easy

Problem: Indicates a problem with the water supply, such as a blockage or the tap being turned off.

How to Fix CHECK WATER LIGHT Error (Step-by-Step)

1. First, locate the water supply valve for your dishwasher, which is typically found in the cabinet under the kitchen sink.
2. Check the valve to ensure it is in the fully open position. The handle should be parallel to the water pipe.
3. Inspect the water inlet hose that runs from the valve to the dishwasher. Look for any sharp kinks or bends that could be restricting water flow.
4. Gently straighten any kinks you find in the hose to allow water to pass through freely.
5. If the valve is open and the hose is straight, turn off the water supply valve completely.
6. Place a towel under the hose connection at the valve and carefully unscrew the hose.
7. Look inside the connection for a small screen filter. If it is clogged with sediment, gently remove it and rinse it clean under a faucet before reinstalling it and reattaching the hose.
8. Turn the appliance off, wait about 2 minutes, then turn it back on.

Error Code: BRUSH SYMBOL Difficulty: Easy

Problem: The dishwasher is currently in the washing cycle.

How to Fix BRUSH SYMBOL Error (Step-by-Step)

1. Identify the ‘Brush’ symbol on your dishwasher’s display. This light is a normal indicator.
2. Understand that this symbol means the dishwasher is actively washing your dishes. It is not an error code.
3. The light will remain illuminated throughout the main washing and rinsing portions of the cycle.
4. It is important not to open the dishwasher door while this light is on, as hot, pressurized water is being sprayed inside.
5. The light will typically turn off when the washing phase is complete and the dishwasher moves into the drying phase or finishes the cycle.
6. No action is required from you when you see this symbol; it is simply providing the status of the current wash cycle.
7. Turn the appliance off, wait about 2 minutes, then turn it back on.

Error Code: BEEPING Difficulty: Easy

Problem: Can indicate the end of a cycle, an improperly closed door, or drainage issues.

How to Fix BEEPING Error (Step-by-Step)

1. First, determine if the beeping is signaling the end of a completed wash cycle. Check the display panel for a ‘Clean’ or ‘End’ indicator. If the cycle is finished, the beeping is normal and will stop when you open the door.
2. If the cycle has not finished, check the dishwasher door. Open it completely and then close it firmly, ensuring you hear a distinct ‘click’ as the latch engages.
3. Inspect the area around the door seal for any obstructions like a stray utensil or a dish rack that is out of place, which could prevent the door from closing properly.
4. If the door is secure, check for potential drainage issues. Look inside the dishwasher at the filter area at the bottom of the tub. Ensure there is no standing water.
5. If you see standing water, you may have a clog. Turn off the dishwasher. Carefully remove the bottom dish rack and unscrew the filter assembly.
6. Rinse the filter components under warm running water to remove any food debris or blockages.
7. Reinstall the filter, ensure it is locked securely in place, close the door, and attempt to resume the cycle.
8. Turn the appliance off, wait about 2 minutes, then turn it back on.

Problem: The automatic wash cycle is selected.

How to Fix AUTO CYCLE SYMBOL Error (Step-by-Step)

1. Recognize that the ‘Auto Cycle’ symbol simply indicates the currently selected wash program.
2. This is a normal operational light and does not signify an error with your dishwasher.
3. The ‘Auto’ cycle uses sensors to determine the soil level of your dishes and automatically adjusts the water temperature and wash time for optimal cleaning.
4. If you wish to select a different cycle, press the ‘Cycle’ or ‘Program’ button on your dishwasher’s control panel.
5. Continue to press the button until the light for your desired cycle (e.g., ‘Heavy’, ‘Normal’, ‘Express’) is illuminated.
