5 Reasons Why Your Dishwasher Doesn’t Clean Right

It must be after a lot of research, thoughts and rumination that you finally decided to invest in a dishwasher. And nothing can be more disappointing than having a dishwasher that doesn’t clean the utensils to your satisfaction. But before you write off your dishwasher, take a look at some of the top reasons why your dishes aren’t clean enough and tips to resolve them.

Water Hardness Is Way Too High

If you live in the metro cities with a hard water supply and TDS higher than 500 ppm, then your dishwasher would have a hard time working effectively. Though you add salt to counteract the water hardness and crank up the salt level to the highest, there is a limitation for any dishwasher when TDS is too high. In such cases, the utensils will retain a white residue after washing. Sometimes, it may also deter the dishwasher from cleaning the food stains properly.

The ideal solution in such a case is to install an additional water softener device. If you are not sold on that idea, then you could use dishwasher tablets along with salt and rinse aid, as this achieves better results.

Poor Quality Cleaning Supplies

One of the main culprits of unsatisfactory cleaning results is poor quality detergent. We have found Finnish dishwasher supplies to be better than others. But even among Finnish, some products work better than the others- especially when it comes to dishwasher tablets.

For example, Finnish All in 1 Max Powerball tablets, though expensive, are excellent in terms of wash quality. Not only does it clean well, but it is also highly effective against hard water residues. But on the other hand, Finnish Powerball Classic tablets lack the same effect even when used along with separate salt and rinse aid.

The Filter Is Not Cleaned

If you find small, grainy bits of food on your dishes after cleaning, or if the dishwasher smells bad, then it is high time you clean the filter at the bottom of the dishwasher. 

You can remove the filter and scourge it with a scrub or old toothbrush to remove any debris. If you need detailed step-by-step instruction on how to clean the dishwasher filter, you can take a look at this article. 

It is also recommended to descale the appliance every month to remove any scaling and hard water deposits inside the appliance and connecting pipes.

Leftovers Have Not Been Scraped

Too much leftover on dishes can clog the filter. Also, those small gritty bits may settle on the dishes after the wash cycle, which defeats the purpose of a dishwasher.

Ideally, you should scrape off any leftovers and rinse the dishes before loading them to the dishwasher. And if you have a scorched pan or stubbornly stained Kadai, it is better to soak them in water for a few hours before loading them into a dishwasher. 

You Haven’t Loaded The Dishwasher Correctly

Overloading a dishwasher or loading it incorrectly is a sure shot method to reduce its cleaning performance. The spray will not be able to reach all the dishes effectively and moreover, the dishes may hit against each other and get scratches too. Placing large pans or Kadai near the door should also be avoided as it may stop the detergent from reaching the utensils behind.

Also, as the technician who came for the demo said, always turn the sprayer arm to ensure it isn’t blocked by any utensils.

Finally, do not use a dishwasher to clean cast iron cookware, cutting boards, non-stick, sharp knives, aluminium and anodized aluminium cookware. These items are not meant to be washed using a dishwasher and should be ideally hand washed.
