Parts Meaning
Care and Maintenance
A regular inspection and maintenance of your machine will help to prevent faults. This saves time and prevents future problems.
Cleaning the dishwasher
- Regularly wipe the front of the appliance with a damp cloth – water and a small amount of liquid soap is adequate.
- For stainless steel appliances (excluding black stainless), use a stainless steel polish to seal and protect the surface.
- Clean the outer edges of the inside door panel regularly to remove debris that may collect from normal loading. If spots begin to appear on the stainless steel, make sure the rinse agent is full and functioning properly.
- Clean the door seal regularly with a damp cloth to remove food particles that may collect from normal loading and cause odor. A soiled door seal may not seal properly.
To check or clean the filter system
- After each wash cycle check the filters for residue.
- Unscrew the Large Object Trap as illustrated and remove the entire filter system.
- Remove the micro filter from the fine filter for easier cleaning.
- Rinse the filters under running water and use a soft brush to clean.
- Reinstall the filter system in reverse sequence and lock into place by screwing the Large Object Trap until the marking arrows align.
Troubleshooting
If the appliance stops during dishwashing or does not start for any obvious reason, first run the cancel wash cycle function.
| Trouble | Remedial Action |
|---|---|
| Dishes not dry. | No or too little rinse aid in the dispenser. Refill rinse aid. |
| Plastic dishes not dry. | Special properties of plastic. Plastics do not dry well because they do not hold heat. |
| Silverware not dry. | Silverware not arranged properly in the silverware basket. Separate silverware if possible, prevent contact points. |
| Appliance interior wet after rinse cycle. | No appliance fault. Dishwashers us “condensation drying,” where humid air condenses on tub walls so it can drain and be pumped out. |
| Food soils on the dishes. | Dishes placed too closely together, racks overfilled. |
| Dishwasher seems to run a long time. | Incoming water is not warm enough. Before starting a cycle, run hot water faucet at the sink closest to the dishwasher. |
| Washable or water-soluble coatings in the container or on the door. | Detergent substances are deposited. These coatings cannot usually be removed with chemicals. Change detergent brand. Clean appliance mechanically. |
| White limescale on the dishes, tub, racks or door. | White residue coats dishwasher interior and racks wheels squeak from lime scale deposits in hard water. Use dishwasher cleaner every few months. If dishwasher has a water softener, increase the setting. |
| Filling valves making striking noises. | Depends on domestic installation, as appliance is not defective. No effect on appliance function. No remedial action possible. |
