White coating on dishes after washing in a dishwasher is one of the most common troubles of machine owners! And, if, for home use, this nasty effect is not so critical, then for the owners of cafes and restaurants it’s just a disaster and torment. Harmful visitors grin squeamishly, have to rinse, and this is an overspending of electricity and water ... Therefore, let's urgently understand why this is happening.
Three main reasons for the formation of plaque on the dishes
There are only three reasons, but this is not any easier. After all, using the pump method to find the main one from them is not so simple. So here is this list:
- Technical difficulites
- Hardness of water
- Wrong selection of detergents
It would seem that everything is simple. But, in fact, not at all easy! Each of these reasons has a lot of nuances and it’s very difficult for a beginner to understand all this.
Therefore, we advise you to start the diagnosis with technical problems in the first place. Of course, if, you know for sure that the dishes were washed off with a bang yesterday, and today, after changing the detergent, a plaque suddenly appeared, then the point is in it. Change it and deal with the end!
But, if you have a new machine, and the very first wash disappointed you, or an old machine that always washed well, but eventually began to leave a coating, then the matter is more complicated.
If you have a machine for a long time, then we recommend that you start the diagnosis in the sequence that is listed in the table of contents.
If it’s completely new, then you need to start with the points: “Poor quality of detergent”, “Incorrect dosage as the cause of the problem”, “Water hardness and how to choose a remedy”, “Decrease in water supply pressure and how to deal with it”.

Jamming of the lid of the detergent compartment and what to do
If before this, the lid worked properly, then it is impossible to immediately notice this. They closed it, left, but the tablet does not think to wash properly. And from this, of course, salt does not enter the ion exchanger.
And salt doesn’t come in, so the water doesn’t soften. And the white coating on the dishes is not the remnants of the detergent, but traces of hard water.
If the cover is broken, you need to call the wizard. Eliminating this problem, white spots on the dishes from the dishwasher will no longer bother you.
Reducing water supply pressure and how to deal with it
When water comes in badly, the machine cannot work fully. And, of course, that the dishwasher leaves a white coating.Detergent is not washed out due to lack of water!
If you know that such a phenomenon takes place, then check this option. A high probability of a decrease in pressure can be if the water supply comes from an autonomous source, a well
Therefore, first of all, check the water pressure in the tap. If you clearly see that he is weak, then the reason is clearly this. Then you should deal with the pump itself.
If, however, you have a central water supply and the water pressure is reduced, then you only have to wait for the moment when the pressure normalizes. Naturally, if, this phenomenon is one-time.
But, if this problem is permanent, then it is worth starting the fight against this. There are several options to solve this issue:
- Cleaning the filter in front of the counter
- Larger pipe laying
- Installation of a pump to increase pressure
- Installation of storage tank and pump station
Which of these methods is right for you, you need to decide on the spot and proceed from the situation.
Clogged holes in the sprayer or filters
Here it is impossible to give a general recommendation, since there are a lot of models of dishwashers. You need to take instructions for your typewriter, find these parts and carefully study the recommendations for removal.
Cleaning them is not at all a problem. As a rule, they are clogged with sedimentary deposits.
The ion exchanger is out of order
But this is already an expensive thing. It can only fail due to the fact that you misused the machine. Namely:
- Ignored the rules and did not add salt when washing
- Replaced special salt with another
If you know that such sins were found behind you, then ... write letters.
Water hardness and how to choose a remedy
If your water has always been not too hard, but gradually you began to notice that the situation is getting worse, then the point is that the pipes at the common station are worn out and the water quality is affected.
You can put a filter, of course. But, it is not so cheap. After all, by and large, a slightly increased water hardness does not bring critical damage. And with a white coating you can fight by choosing the right remedy.
Rinse aid is a must if water in your tap is hard. And, if, before that, you could safely do without him, now circumstances have changed and you will need to acquire.
Incorrect dosage as the cause of the problem
Here the statement is very suitable: "When there is a lot of good, it is no longer good." Do not exceed the recommended dose, as the product simply cannot be washed completely.
Even if your dishes are too dirty, you should not expect that a double dose will solve this problem. It is better to wash at elevated temperatures in this case.
Poor quality detergent
Well, here, as they say, no comment. We recommend that you always read reviews online before buying any powder.
Indeed, there is nothing more offensive to buy and toss out the entire package in frustration ...
We hope that now - a white coating on the dishes after washing in the dishwasher, it will not be a problem for you and you can overcome it yourself!
