After flush the system must close the hole which lets water into the toilet. If it does not close after flush, it is continuously letting the water thru. Check if it closes after flush and allows tank to fill.

The tank holding the proper amount of water is a good sign. The inside of the stool is like the GOOSE NECK under you sink. It always holds water. This may sound like a bit of a hassle to do but if all 3 toilets are identical, here is what you can try if you are a bit handy. Go to the hardware store and purchase 4 toilet wax rings with a plastic flange and a few sets of toilet floor flange bolts(they are cheap and you can always return if not used, as It is better to have xtra parts on hand). Turn off the water supply to the "Mystery Toilet". Leave the tank and everything connected to the stool. Flush the toilet and remove all excess water from the tank and bowl. This can be done with a shop vac, sponge or towel. Disconnect the water supply to the tank. Remove the bolts holding the stool to the floor and carefully remove toilet. Scrap off all the old wax from the floor flange and bottom of stool. Now go and repeat this proceedure to one of the toilets that is working properly. In other words Switch the "Mystery Toilet" with a "Working Toilet" and see how they react. If the working toilet does it in the same bathroom and the "Mystery Toilet" does not do it in the other bathroom then you probably have a VENTING PROBLEM. If the "Mysery Toilet" Does it in the other bathroom then you most likely have a Defective Toilet. This Job is best done by 2 people, as it can sometimes be challenging to center the new wax ring on the toilet flange. Reconnect to the floor and reconnect water supply to the tanks. DO NOT OVERTIGHTEN BOLTS to the floor flange as you may crack the toilet. All drain lines must be vented properly for water to flow. If you are curious check out drain venting on the internet. Also, sometimes a vent can become obstructed with debris, ice, bird nest, etc.. I would 1st check the vent on the roof visually and then have someone flush and listen. If you believe the vent is clear....Then do the toilet switch and go from there.....Hope this helps and Happy Holidays....Joe
SOURCE: toilet not flushing properly
there are allot holes around rime inside they get clogged over time because water quality very hard to get there to clean best bet replace toilet
SOURCE: valve adjustment
You need to replace the flapper and you will need to purchase one specifically for the Kohler toilet. I have the same toilet and tried using a generic flapper and from experiance, it didn't work until I bought the correct one and I'm a plumber! Have a great night.
SOURCE: tank won't fill unless I push down on flush valve inside toilet
Hello there
ok first when the valve inside of the tank is wearing out or is dirty this will happen you can take a washrag and clean the underside of themechanism really good and also the part that it rests on providing that you can get to it
if there are no screws to adjust the water reg valve see if it will turn clockwise to shorten the arm making it turn off or if needed turn it counter clock wise i have had to also slightly bend the arm down in some units to make the water stop after the tank is full so you may want to try that too ok
hope that this helps
best regards michael
