Dishwasher clogged

I have recently had the problem that my dishwasher ignored the upper floor. So the dishes stayed "dirty" at the top. I clean the sieve regularly before "washing".

Since I remembered a tip here in the forum, which was actually intended for clogged drains. So I unscrewed the sieve, poured 2 packets of baking soda into it. Then add 1 tbsp vinegar essence. Then sieve screwed on again and the machine given 10 minutes rest. Then the machine started. And behold, after the washing program was over, my dishes were clean. Also in the upper floor!
