To ensure optimal cleaning, place large items like pots and pans along the sides and back of the dishwasher, angling them towards the spray arm. Ensure that all items are spaced out to allow water to reach all surfaces. Place cups and glasses on the top rack, and avoid blocking the detergent dispenser.
First, check the drain hose for any kinks or blockages. Then, inspect the dishwasher's filter for debris and clean it if necessary. If the problem persists, the drain pump may be faulty and require professional service.
Open the dishwasher and remove the lower rack. Twist the cylindrical filter counterclockwise and lift it out. Rinse the filter under running water to remove debris, and use a soft brush if necessary. Reinstall the filter by aligning it properly and twisting it clockwise until it locks in place.
To descale your dishwasher, remove any dishes and pour a descaling agent into the detergent compartment. Run a full wash cycle without any dishes, using the hottest water setting. Follow the descaling agent instructions for optimal results.
White residue is often caused by hard water deposits. Ensure that you are using an adequate amount of rinse aid, and consider using a dishwasher cleaner to remove mineral buildup. Adjusting the water softener setting may also help if your model has this feature.
To reset the dishwasher, press and hold the start button for about 5 seconds until the display clears. This will reset the current program. For a full factory reset, consult the user manual for specific instructions as this process may vary.
Check for any loose items or utensils that might be hitting the spray arm. Ensure that the dishwasher is level and that no parts are obstructed. If noises persist, there may be an issue with the motor or pump, which may require professional inspection.
Regular maintenance includes cleaning the filter monthly, wiping down the door seals, checking and cleaning the spray arms, and descaling the dishwasher every few months depending on water hardness. Regularly inspect the hoses for leaks or damage.
Ensure that the rinse aid dispenser is full, as rinse aid helps with drying. Select a higher temperature wash cycle if available, and leave the door slightly open after the cycle to allow steam to escape and enhance drying.
Refer to the user manual to identify the error code and follow the recommended troubleshooting steps. Common solutions include checking for blockages, resetting the unit, or contacting customer support if the problem persists.
