If The Dishwasher Does Not Wash Cleanly

If the dishwasher causes problems, you don’t always have to pay an expert. Sometimes a few handles are enough, and the dishes get clean again effortlessly.

If you once had a dishwasher, you probably never want to miss it again. Used dishes become effortlessly clean, and depending on the device, you even need less water than with hand washing. However, it happens again and again that some stubborn food residues survive the rinse. How to make sure your dishwasher washes clean and also eliminates unpleasant odours.

If, after the washing process, leftover food and dirt on the dishes and inside the dishwasher may be due to the water hardness. In the case of very calcareous water – more than 21 degrees of German hardness – the multifunctional rod’s water softener cannot be sufficient. It explains the Industrial Association for Personal Care and Detergents in Frankfurt. In this case, you should also add regenerate salt to the water tank. The use of rinsers can also help.


Disorderly clearing makes the dishes cleaner

The foundation stone for clean dishes is laid as soon as you clean it up. Sensitive parts belong upwards, heavily soiled dishes down. It is also important that the water can reach any angle. Therefore, you should not evacuate your machine too fully and align heavily polluted parts towards the water jet – or rinse it briefly under running water in advance. Order is not necessarily required. On the contrary, a little chaos in the machine ensures a better washing result. Thus, the water is directed into all corners and spaces rather than with accurately admitted dishes.

Do not set the dishwasher too cold.

The cause of ugly deposits may also be too low a dosage of the detergent. Or the rinsing temperature, for example, in the savings or eco-program, was too low. If the eco-program is used daily, the industry association recommends that the machine be run once a month at a rinsing temperature of 60 degrees to prevent deposits. In this way, you also avoid unpleasant odours in the machine caused by bacteria and germs inside.


Hot rinse prevents odours.

Since germs also multiply on residues in the filter and on seals, you should clean these areas regularly with a cloth and appropriate cleaning agent.

If the bad smell cannot be expelled in this way, it is worth looking at the sewage hose. If it is bent, too much residual water can accumulate in it – a biotope for germs, according to the Forum Waschen.

If it smells in the machine, especially if it has not run for a long time, the smell usually disappears the next rinse. Therefore, for longer downtimes, it is useful to choose the program “pre-rinse” and use a dishwasher deo, the forum advises further.


Ready meals leave stubborn deposits

The remnants of ready meals on the dishes can also be problematic. These can contain hardened greases with a particularly high melting point, deposited in the machine room on plastic parts. Such fats are often only dissolved by a higher rinsing temperature and a higher dosage of detergent. In this case, it is best to dispense with the Eco program and let the hygiene program go through once – even without dishes if necessary.


Wash glasses clean in the dishwasher

Especially glasses are often not completely clean when they come out of the machine. After a few runs in the dishwasher, they often look milky, or they only shimmer matte. Often this turbidity is caused by salt or lime. In this case, fixing the problem is easy. Check the salt tray and the correct dosage.  


Prevent glass corrosion

Lime deposits are formed by too hard water. In this case, check that the softening system in the dishwasher is set correctly. The best way to correct the settings is to refer to your machine’s user manual.

Citric acid also helps against lime stains. However, guilt can also be a heavy load on the glasses in the dishwasher. However, glass corrosion cannot be corrected. It is caused by frequent rinsing at high temperatures and the soft water used in the dishwasher. To prevent this phenomenon, the rinsing temperature should be kept as low as possible. Furthermore, a dishwashing detergent with special glass protection can also create improvement. Susceptible glasses such as heirlooms should be rinsed by hand if possible.


Tabs or powder?

Whether tabs or powders are better is not yet proven. The powder has the advantage that you can dose it individually. However, you also have to pay attention to the correct storage – too high humidity causes the dishwasher powder to clump quickly.

On the other hand, tabs have the advantage that they are easy to handle and usually contain several components – cleaning, rinse, drying. However, if the dishwasher is only half full or if the dirt is not as strong, tabs contain too many additives and chemicals compared to powders.


Avoid air rust

If rust is visible on the cutlery after the rinse, this can be flight rust. This occurs when there is an object in the dishwasher that rusts. Through the rinse, the rusty particles are distributed in the machine and settle on other objects. In the case of flight rust, you should therefore check not only the rinsed parts in the machine, but also the individual parts – such as sieve, cutlery basket and co. – for rust.


If the dishwasher is rattling during cleaning

In some washing processes, it rumbles and rumbling in the dishwasher. Especially the sound of swelling water can cause concern. Next time you don’t hear anything. What’s going on? On the one hand, the dishes are conceded a little differently each time. Loosely seated objects can rattle. On the other hand, the water does not always leak from all spray arms and spray nozzles simultaneously, explaining the forum Washing. Also, the pressure of the water is changed again and again during the washing process. According to the cleaning experts, there may be noises that give a restless impression during the change in the water flow.
