Step-by-step troubleshooting
- Identify the Error SymbolDo: Locate and note the displayed error symbol on the control panel.Observe: The symbol may be a water droplet, flame, padlock, or other icon.Means: The symbol corresponds to a specific issue (e.g., water supply, heating element, or lock mechanism).Next: Consult the manual for the symbol's meaning.
- Check Water SupplyDo: Ensure the water inlet valve is open and the supply line is not kinked.Observe: Water flows freely from the supply line to the dishwasher.Means: A blocked or closed valve restricts water flow, causing error symbols.Next: If water is flowing, move to the next step.
- Clean the FilterDo: Remove and clean the dishwasher's filter using a soft brush and water.Observe: The filter is free of food debris and blockages.Means: A clogged filter can prevent proper drainage and trigger error symbols.Next: Reinstall the filter and run a test cycle.
- Inspect the Drain HoseDo: Check the drain hose for kinks, clogs, or improper connections.Observe: The hose is clear and connected properly to the drain system.Means: A clogged or kinked drain hose causes water to back up and trigger errors.Next: Clear any blockages and ensure the hose is secure.
- Reset the DishwasherDo: Unplug the dishwasher for 1 minute, then plug it back in to reset.Observe: The error symbol disappears and the dishwasher operates normally.Means: A reset can clear minor electronic glitches causing the error.Next: If the symbol returns, proceed to the next step.
- Check the Heating ElementDo: Visually inspect the heating element for damage or mineral buildup.Observe: The heating element is intact and free of corrosion.Means: A faulty heating element can cause error symbols related to heating issues.Next: Replace the heating element if damaged.
