Nivon 757 Coffee Maker Issue: Water Accumulating in Coffee Grounds Tray

Question

Hello, I have a problem with the Nivon 757 coffee machine. For some time, a trace of water (a few drops) has appeared under the coffee machine. Recently, water was not flowing through the nozzle when flushing before starting. After another rinse attempt from the rinse option, the water flew out...

From what I remember there is an electric multi-valve at your place. I am asking you to check it first

rosos · Answer

How to check it? Any tips, advice ...

nioop · Answer

For leaks - Remove the housing and look for leaks Coffee in a coffee grounds container? But it's coffee for drinking or ground coffee?

rosos · Answer

Coffee after brewing - to drink

nioop · Answer

Well, there is nothing else but to brew coffee without housing and observe what is happening.
If it was a leak, then the next attempt to make coffee would also take place ...

In this case, I suspect an incorrect arrangement of the block, however, the reason must be observed as mentioned above.

rosos · Answer

Does this multivarius have a different name - drain valve?

nioop · Answer

no, there is no other name known to me. The drain valve is another element responsible for draining the water to the drip tray

rosos · Answer

nioop · Answer

How to get to him?

nioop · Answer

Yyy .. Take off the upper casing

rosos · Answer

Hello,
I undressed the espresso machine and identified the leak. As you suspected there is a leak from the multivibration valve. Below the photo and the place of leakage marked.

What can you do about it ??

As for the lack of coffee in a mug is another fairy tale. I found the problem. The water flies through the brewing unit.
Below is the movie.

What could be wrong?

nioop · Answer

The multisaw can only be replaced.
I got tired of downloading this movie

And I did not see anything there ...
Is it not a drain / drainage valve that leaks? Please, light the flashlight and locate the leak point and replace the damaged element.

rosos · Answer

Where is the drainage profession ?? I have downloaded the film without any problem, the film shows how the water is coming from the places marked on the photo. [/ Img]

nioop · Answer

You can see the water, you can not deny .. you can not see the place where it flows. It will be difficult to grasp, therefore, it suggests that visually the Lord himself will check which element is leaking.

rosos · Answer

The water flies from the brewing machine, in the picture I marked the place of the leak. Can anyone know what the reason is? Maybe someone has already encountered such a problem.

Welcome to the forum.
I have a similar problem after three years, I think. After removing the brewing unit and setting it in the brewing position, after blowing into the upper nib the air from this hole is flying.
Questions to forum members:
Is this hole a safety valve?
Maybe someone has a schematic of building such a brewing machine?
Does the brewing unit smudge somewhere inside?
What could be the reason for the leakage of that hole?
I will be grateful for your help.

rosos · Answer

To replace the brewing unit.
