[Solved] Geberit WC - 2-way drain valve art. no. 240.622.00.1 - out of order

I have a GEBERIT cistern installed in the toilet, art. No. 110.302.00.1, year of purchase around 2003 (unfortunately my bill has been lost somewhere). It is probably a Geberit Kombifix for the toilet, which is due to the number of the article stuck inside the tank, although one of the sellers during a phone call claimed that it was a Duofix.



Installed toilet flush plate Twist (cut egg):


There is a 2-way drain valve in the cistern which does not function properly.
From what I found out in the materials available on the Internet, this is art. no. 240.622.00.1 Download



The hooks visible at the top are for draining the water. The one on the right of a small number, and the one on the left - a large number.

The problem is that by pulling the one on the right to flush a small amount of water, the hook can be pulled all the way to the top of both the tank and the flushing does not take place. The one on the left is working fine.


There is a hook in the mechanism, visible in the photo, which, in my opinion, should catch in the visible hole when rinsing with a small amount of water, but it pops out of it.
I watched it carefully:

but no damage is visible on it.

Please let me know how the flushing mechanism works with a small amount of water and what is the cause of the failure.
I think that if I know how these parts should work together, I will remove the failure without any problems.

Hello, I have a similar problem, rinsing with less water does not work for me, This hook "pops up" too. I don't know exactly what the Geberit model is, but it looks like the one in the picture. Did you fix it or did you need to replace the valve?
How to remove this valve at all (unscrew it if you need to pull it out), I would not want to damage anything.

I had the same problem. I wrote an email to Geberit and despite the fact that I did not have a receipt for the purchase (the previous owner assumed), I was very pleasantly surprised by this company. You called me from the service. We made an appointment to repair. Two days later he came and exchanged. Of course, everything is free. Also, I know only Geberit.

In the 2nd photo - the middle element with a square hole at the top (such a cone) has two hooks securing it to the body below in 2 places (left and right). It should be disassembled with sensitivity (because it is plastic), pry so that the hooks pop out of the holes. The same applies to the element with a square hole on the right and then you will be able to tilt the entire valve and pull it out of the hole in the bottom of the flush at an angle.
You have to reduce the length of the valve (height) or it won't come out.
You will see for yourself what will stand in the way of pulling out.
I was able to buy this valve for about PLN 50. The "normal" price is about PLN 80.

Hello

Old topic, but maybe someone knows why the water drain does not work in these Geberites?
The valve looks undamaged, everything is assembled correctly and the drain is not working. The lever from the photos pops out of the casing and does not pull the caisson.

Broken catches. You can't see it, but at 99.9% it is. The situation is the same as for me. The valve to be replaced with a new one - unfortunately expensive.

Thanks for the answer. So it only remains for me to replace.

That's right, these plastics tend to have tiny tears that are dense and hard to see.
If it does not function properly even though all components are in place, there is a slight crack somewhere - a damage that is difficult to locate.

Old topic, but after reading it, I made an attempt to fix it.
The green tongues at the top of the cup break and lift the entire white central pipe. I found only one, the second one has probably been flushed with water a long time ago.
I drilled 2 holes on both sides and tightened the screws. After putting the green cup on the white pipe, I unscrewed them slightly so that they hooked and lifted the pipe later.
It flashes like new and saved several dozen zlotys.

Thanks a lot for the hint, because I had the same problem. At first I thought it was the white hook that raised the entire trigger, but actually at the top of the green element there are two tabs (in the middle) lifting the white plunger and they broke off. After screwing in the two screws in their place, everything works as it should.
By the way, I have no idea what function this white hook at the bottom performs.

Many thanks, gentlemen, I couldn't find out what was going on and I was about to call a professional. I found your solution to the problem, I undressed again and also found only one broken fragment so I got where it should be. I also screwed the screws into the drilled holes in the white element and so far it works Costs postponed for a while. Greetings.

Hello colleagues
I have a request for help on a topic that, as you can see, causes a lot of problems and concerns the two-part drain valve art. no. 240.622.00.1. I have no problem with the operation of this valve and its leakage through the drain seal. I tried to disassemble this valve, looking for a feeling, because unfortunately you can not see anything there. The elements that will allow it to be disengaged, but I could not feel it. Could someone who has already mastered this art in a few sentences write how to do it and in which way to shoot so as not to tear anything off. If we could still attach some photos, I would be grateful.
Thank you in advance for your help

Detach the larger white element (the pipe) by turning it counterclockwise about 1/4 turn and fold it out to the side. Upwards from the valve axis to the outside - you can help yourself by pressing your finger on the upper part of the valve mounting. Should help

Hi
Thank you so much for help. I have already ordered the gasket and will try to remove it.
greetings

Thanks for the hint, I had the same problem with Geberit yesterday, but thanks to the hints here - already fixed.

The white hook at the bottom must be slightly hidden in the opening of the outer body - otherwise, after flushing, the water does not fill the tank and flows freely into the sewage system.
Therefore, in place of broken plastic hooks, the screws should be screwed in as high as possible (even slightly slanted) - so that the white hook remains hidden in the external body.

I did the classic way. 5 minutes and everything works.

Where exactly should these green hooks be?

It would be immediately visible with the black band. Only when I got a better look did I understand what was going on

The repair with two screws has worked well. It's been over two years now and the flush is still working fine.

Could someone toss a photo where exactly should these screws be screwed in?

I have a Geberit concealed frame and the problem is that when flushing, the water does not wash the front part
bowls. As if the force of the water outlet was too small.
I have the marking on the reservoir: 111.320.00.1 and further: 01.14.01.04-2.3-KIWA
Could this valve, gasket be the cause?

The point of contact of the green part with the white part must be in a place where (with the strands of these elements aligned) the top of the green part is aligned with the "protruding ring" (red arrows). It does not have to be super accurate, but it cannot be a situation that the small element cannot fall down enough to close the drain in the cistern. In the photo borrowed from the post above, I marked the place where you can screw the screw with a blue arrow. It can also be screwed into the green element. I used a clamp, but just above this white bulge, not below like in this photo, because the drain valve did not close.

The patent is 100% effective. Thanks to you, I saved PLN 100. Greetings.

I confirm that the repair method is simple and 100 percent. effective. I was close to solving this problem, but the hooks of the green element were both broken and I did not find that they were missing. It seemed to me that some ring is missing, which broke and ran off the water. For me, the screws have passed the exam. The cistern is 12 years old and has lasted so long. Thanks for the help. Greetings to Geberit, less and less equipment can be repaired at home.

Thanks to the gentlemen. I was also thinking about buying a new cistern because a small flush does not work for me, and here is something ... Congratulations for your ingenuity and best regards. Saved PLN 100

Thank you gentlemen, I'm going to the store for "tights"
