DeLonghi DDW60S20 Instruction Manual

Ensure that dishes are not blocking the spray arms. Place larger items at the sides and back, and ensure that all items are securely positioned. Cups and bowls should be placed facing downwards.
Check the filter and drain hose for any blockages. Clean the filter if necessary. Also, ensure that the drain hose is not kinked or clogged.
The filter should be cleaned once a month to ensure that the dishwasher runs efficiently and to prevent any blockages.
Use only dishwasher-specific detergents. Tablets, powders, and gels designed for dishwashers are all suitable. Avoid using regular dish soap.
To reset the dishwasher, switch it off, unplug it from the power source, wait for about 10 minutes, and then plug it back in. Turn it on and try running a cycle again.
This could be due to hard water. Try using a rinse aid to help reduce mineral deposits. Ensure the salt reservoir is filled if your dishwasher model requires it.
Check for any foreign objects in the dishwasher that may be causing noise, such as utensils falling out of the rack. Also, ensure that the dishwasher is level and not touching adjacent cabinets.
Regularly clean the filter, check the spray arms for blockages, and wipe down the door seals. Additionally, run a cleaning cycle with a dishwasher cleaner every few months.
Inspect the door gasket for any damage or debris that might prevent a proper seal. Also, ensure that the dishwasher is level and that the hoses are securely connected.
Ensure that the rinse aid dispenser is filled, as this helps with drying. Also, use the heated drying option if available, and leave the door ajar for a short time after the cycle ends to allow steam to escape.
