Residues on dishes ⇐ Dishwasher chemicals

[Rita]

Good afternoon Dear dishwasher users, I have a problem of this nature: I’m worried that there is detergent left on the dishes after the wash cycle. Sometimes I notice visible stains on the plates, so I rinse them by hand. But even if there are no visible traces, this thought does not allow me to live controversially. I use finish gel, as they say the gel dissolves better in water. Can you recommend something?

[Pavel]

I have the same problem, the machine is new, and after washing the detergent remains on the dishes. I use finish tablets. The dishes are slippery. Bosch dishwasher series 2. I even tried throwing a third of the tablets, still the same, the dishes are slippery.

[Boševec]

the machine is new,

I apologize for what may be a stupid thought - do the rocker arms spin? I just had this happen recently when I forgot to remove one of the rocker arm fasteners on a new car. It’s just that because of this there is not enough splashing and the product is not washed off.
Or the nozzles are clogged, it happens that fish bones get into these holes.

[Elenka]

do the rocker arms spin?

How can you see this in a working machine? You can turn them manually, you can clean the holes with a toothpick and rinse them under running water, but once you put them in place and turn on the machine, how can you see what they do and what they don’t?

Dishes are slippery due to rinse aid, reduce dosage! Whitish stains are mainly due to lack of salt, increase the dosage! Less often, all these problems are caused by short washing cycles, improper placement of dishes and overdose of detergents!

We cannot solve the problem of soapy dishes. For example, we have already tried with no rinse aid and with a small dose of rinse aid, and on short and long washing cycles, and at 65C and 50C, we halved the amount of detergent - but this measure gave a slight improvement.

What is your water hardness?

[Granitol]

0.8-1.1 mmol/dm3 - St. Petersburg, our water from the Neva is very soft, no scale forms. Salt, of course, was not added to the machine, the softening system is at zero.
In general, the feeling is that there is a failure in the programs, the machine simply stupidly does not rinse enough, because if some small amount of water gets stuck somewhere - for example, on the bottoms of cups - it is always soapy.
We have a different machine at work, there are no such problems from the word “at all”, the dishes are not slippery, if there is water left somewhere, they are clean. So we have something to compare with.
We are now trying to contact the service, but I’m afraid the same thing will happen there - "you put too much detergent".

This was my answer, for some reason I was thrown out of my account =)

The water is very soft, try setting the water hardness and rinse aid to 0, no 3 in 1 tablets, only powder or classic tablets without additives, Bio-Mio is not suitable, they contain impurities for water softening, in my region the water hardness is 4g, PMM 60cm, with a full load, 10-15 grams of powder or half a tablet weighing 20 grams is enough, everything washes perfectly, if the PMM is 45 cm, then a whole tablet or 30-40 grams of powder, as the manufacturers recommend, is a lot, so if the service center says that there is too much detergent, then they to some extent they will be right, with very soft water like yours, the detergent will foam more, it will be better to wash, but unfortunately it will take longer to wash off)

[Vika-Nika]

Matrix, apparently you haven’t read everything =))) I wrote to you above about the hardness settings that they are at zero =))))) but what does the rinse aid have to do with it? In addition, as experience has shown, the amount of rinse aid does not affect the soapiness of the dishes; I wrote above that we also tried without rinse aid. =)))
If you put less than 20 grams, then the dishes don’t wash well, they are soapy and dirty =)
As for the type of detergent, I wrote that there are no such problems at work in the car arises at all, never, at all. Even if we put half a tablet, even a whole one, even if there are 10 plates, even 20, the dishes are never slippery, all the water that remains on the dishes is clean - I also wrote about this above. By the way, she rinsed everything well, even when one of the rocker arms did not spin, they blocked it with a bowl - oh, how! And water is supplied from the same water supply with the same hardness. I brought home the same tablets, everything is soapy after washing.

When, under equal conditions, two machines show such different results, a suspicion creeps in that one of them is faulty. Or Bosch makes new, built-in machines that are significantly worse in consumer qualities than the old (5 years old), free-standing Kandy ones - apparently, this also cannot be ruled out.

Is your hose for draining water from the PMM into the siphon installed correctly? Is the water pressure at the inlet to the PMM normal? Is there anything preventing the waste water from draining? There may be a blockage somewhere in the siphon)

No, they installed a new siphon two weeks ago, there is definitely no blockage there, and you can’t feel the blockage in the sink at all. The water pressure is normal, at least not lower than what I usually see in apartments. Everything is most likely connected correctly, but I am not an expert in this matter, as well as in the operation of PMM. I can only compare my actions with one PMM and with another, and the result of the same actions. Actually, if we call a specially trained person - a master - maybe he will see what’s messed up, but there are no obvious mistakes, everything is clearly according to the instructions.
In addition, for rinsing we are forced to run a short cycle for an hour, naturally , no detergent, everything rinsed perfectly after that. Apparently there is no reverse flow of water (if such a thing is even possible, but it happens in washing machines), because. no sewer smell in the car.
