How to remove the cistern from the KOŁO SLIM frame no. 99235?

Hi,
I have a KOŁO SLIM frame no. 99235 with cistern no. 99235004.
I dismantled the button, took out the tank filling mechanism, but I can`t figure out how to remove the cistern...

Maybe someone of you has a video or understandable instructions (step by step). The results in Google are already looping and I keep finding (ironically -)) the same thing over and over again.


best regards

Hi.
Were you able to dismantle the valve? I have the same problem and I`m still struggling with it.

Yes - there is a rubber connector - I just bent it hard in this place. Not very intuitive, but it worked.

Rubber connector? And what does it have in common, where to look and look for it? I remove the top piece with the two holes for the buttons. The filling valve is on the right.

Edit.
I already know what connector it is. It is best to first remove the upper "ears" that pull the valve upwards when the buttons are pressed. Then unlock the side cables connecting to the float. And then you have access to the rubber connector, lift it, tilt it a little and it can be removed.

Buddy, did you dismantle the water supply first? I have to replace the gasket because it sometimes drips and leaks irregularly. I understand that you dismantle the connectors along the rubber connector and then "break" the element when pulling it out?

Exactly. I leave the filling valve on, it doesn`t interfere with anything. I don`t even unscrew the supply pipe. Just remove the top links and disconnect the side links and you can remove it. When lifting, you gain access to the rubber connector. You can gently help yourself by tilting to one side, but this is not necessary. The first time I even managed to remove them without disconnecting the side ones, because they are so flexible. However, I prefer to save them and not risk them breaking one day.

Ok, I ordered a new gasket . The thickness of the inspection hole is several centimeters even though I assembled the set only on one plasterboard. In my case, I will probably have to remove the reinforcements along the rubber. Have you replaced the gasket?

I just cleaned it under running water. Earlier, I poured citric acid and warm water into the tank. Thanks to this, 95% of the dirt and limescale washed itself away. All seals are functional.

Hello everyone.

I have a problem with the Koło slim flush.
The strength of the water flushing stream is too low, it is visible that the water does not reach the front of the toilet bowl.
I dismantled the drain valve, cleaned it, and made sure there was no blockage under the water outlet, unfortunately to no avail.
Please help me in this matter.

Thanks in advance.

You have to unscrew the bowl and there is probably a gland in the water drain hole in the form of a plastic mesh stuck with a stone. It`s best to remove it. Or clean it.

before I looked here, I was thinking about removing this valve because I was afraid of bending it in the place where this thick rubber is, but after reading your advice, I gained courage and I DID IT!! although after inserting the cleaned valve, water still leaks from the cistern into the toilet bowl.
I don’t know if buying a new drain valve will help, because the cleaned one looks like new and the seal is not damaged either.

I decided to replace the gasket, but it is still leaking. I also think that the reason may be that the gasket adheres too poorly to the white piston filled with Styrofoam. Can anyone tell me whether the seal and the piston should fit very tightly together? Maybe gluing the gasket would help, but then what should I glue it with?

The NEW drain valve solved the problem!!
By the way, I would like to inform you that there is no problem with inserting or removing the NEW VALVE through the inspection hole because the black rubber is flexible and can be bent and the valve can be installed without any problems.

Hello, what is this long blue plastic attached to? Thank you for the information.

Hello, I have a problem with the Slim set described in this post. First replaced the gasket, it didn't help, then the entire valve was replaced, and it still leaks. Does anyone know what else I can do to prevent water from leaking?

Hello.

The problem is probably solved now, but I will write it for the next people struggling with the slim wheel. If water is still leaking after repairing the drain valve, you need to pay attention to the filling valve. You need to remove it, descale it, and check the seal.

How to check if it's the filling valve's fault?

1. When the water is drained, it does not leak.
2. When the tank is full, it does not leak, but after a short time, it starts leaking.
3. When the tank is full and you can still hear a slight noise from the filling hose.
4. When, after a short time, after the tank is filled, the water level rises so much that the water begins to flow through the opening protecting against overflow.

I replaced the gasket, but unfortunately, it was worse. I decided to replace the filling valve.
