After flushing, wather doesnt come up in bowl evan if ball close hole good.

conventional flush: push lever, chain lifts "flapper" over the hole to allow water to enter bowl. As water goes down in tank, flapper covers the hole to allow the tank to refill. The small tube that dumps water into the standup, larger tube is what fills the bowl back up. Otherwise it would stay in a low water position allowing sewer odors into the structure. If the water does not stop, your fill valve is not shutting off. Probably needs an adjustment. If adjustment does not fix, replay flush valve.

The holes around the inside of the bowl may be clogged, try using some CRL and scrubbing the holes with a good stiff brush.

You should use a ball that weighs around 1/10 of your body weight. If you weigh 90 lbs., pick an 9 lb. ball. Try to put your fingers in the ball holes, your thumb should go all the way into the ball for a good fit. The fingers and thumb should touch all the way around the holes without being tight.

This usually indicates one of two things: (1) a poorly seated flush valve ball, which can be easily adjustedor replaced, or (2) a flush handle chain that is too long and is getting caught between the flush valve ball and the seat, which is easily remedied by shortening the chain between the flush handle and the flush ball.

One other possibilty is that the fill valve is not shutting off the bowl wash function. There is a small adjustment screw for regulating the flow.

Here's how I fixed the same problem on a different model toilet.

Its simple. Check to see if you installed toliet right by removing top of tank and holding handle all the way down. Did it flush from all rim holes? If not, then u will need to get a garden hose with a sprayer to increase pressure and shot high volocity water at rim holes to unblock it. Remember the very front on newer blows do not have holes its a pee shield. Also try doing these other things adjust screw inside tank to make sure the bowl has enough water in it to do a good job. Check the rubber tube going into the hollow pipe and make sure it is going fully inside the plastic pipe that is sticking out of the top of the water in the tank. Also you need to have enough water in tank to allow it to flush good. To increase tank water levels then just unscrew the big plastic ball (or just bend wire to allow more water or bend to allow less water) at top of water in tank. Also increase (max) water pressure at wall to allow it to work at its best. If you have hard water it can cause problems but you say it happened even new, so, you do not have to go in that direction.

adjust the flappers-- either adjust the length of the lift line-from flapper to handle and or the flapper itself not properly mounted on tank seat

Make sure the water level is the same in both tanks, so you know the water volume will be the same for both units when flushing. Next, hold the handle down for the full flush release to make sure the flapper (in the tank) is not closing too soon and cutting off the full water volume needed. Next, would be to get a tolet snake reamer (buy the cheapest one) and run it through the toilet bowl 3 or 4 times always turning clockwise while entering and while removing. If all this does not cure the problem, then you probably have a defective toilet outlet hole that was made too small when the toilet was formed. The outlet hole must be minimum 1 5/8 inch diameter (most are between
1 3/4 inch to 2 1/4 inch diam.) . This is an occassional industry problem; I have seen it several time over the many years. To confirm this, you need to remove the toilet and measure the hole, or get flush balls of 1 5/8 inch with 4 ft. string attached. If the ball flushes and takes all the string slack, then the hole is at least correct minimum size. If ball does not completely flush after 3 tries, then there is some obstruction or the hole is too small and toilet it therefore defective. Goodluck, Macgivor

yeah sounds as though the ball valve or water inlet valve is stuck in the closed position or jammed so when you flush the loo the water doesnt refill.
Isolate water service remove valve as required clean/replace re instate test & leave working
