A dishwasher is an indispensable kitchen helper that saves time and effort. However, it may sometimes fail to perform well, leaving dishes dirty, stained, or covered in residue. Let’s explore the main reasons behind this issue and how to resolve it.
Clogged Filters and Spray Arms
Over time, food particles, grease, and limescale can accumulate in the filters and spray arms, blocking water flow. As a result, dishes don’t get cleaned properly.
What to do?
- Remove the filters and rinse them under running water using a soft brush.
- Check the spray arms. If the holes are clogged, clean them with a toothpick or needle.
- Use specialized dishwasher cleaners to remove buildup.
Incorrect Loading of Dishes
If dishes are packed too tightly or block water access, even the most advanced dishwasher can’t clean them properly.
How to load correctly?
- Place large items, such as pots and pans, on the bottom rack.
- Lighter items like plastic containers and glasses should go on the top rack.
- Ensure there is enough space between dishes for water to circulate freely.
Low-Quality Detergents
Not all detergents are created equal. Cheap powders or tablets may not dissolve properly, leaving residues and even damaging the machine.
Solution:
- Use reliable detergents suitable for your dishwasher model.
- Add dishwasher salt if you have hard water in your area. This will improve cleaning quality and extend the machine’s lifespan.
Water Temperature Issues
Hot water is essential for removing grease and food residue. If the water isn’t hot enough, dishes will remain dirty.
What to do?
- Check your machine’s settings. The water temperature should be around 60°C.
- If the water isn’t heating, it may indicate a malfunction. Dishwasher repair troubleshooting might be required.
Worn-Out Components
Over time, parts such as door seals or spray arms may wear out. This can cause leaks or reduce pressure inside the dishwasher.
How to spot the problem?
- If you notice leaks or unusual noises, check the seals and replace them if necessary.
- For complex issues, call a technician for servicing.
Hard Water
Water with a high mineral content can leave white residue on dishes and the machine’s interior parts.
Solution:
- Regularly add dishwasher salt to soften the water.
- Use vinegar or citric acid for preventive cleaning to remove limescale buildup.
Professional Maintenance Needed
Even with the best care, your appliance might need professional attention. Regular washing machine services and dishwashers can prevent serious malfunctions.
When to call a technician?
- If dishes remain dirty despite your efforts.
- If the machine makes strange noises, leaks, or doesn’t drain water properly.
How to Prevent Dishwasher Problems?
To ensure your dishwasher works efficiently and lasts long, follow these simple tips:
- Clean filters and spray arms once a month to remove residue and buildup.
- Use high-quality detergents and add salt if needed.
- Avoid overloading the machine and load dishes correctly.
- Perform regular cleaning to remove grease and limescale.
- Remember that maintaining washing machines and dishwashers can help prevent sudden breakdowns.
A dishwasher may fail to clean properly due to clogs, incorrect loading, water issues, or worn parts. However, most of these problems are easy to fix. Regular care and timely maintenance will extend your appliance’s lifespan and keep it running efficiently.
