Noise of flush water

No ,you have to hold button to get full flush

Prelude:
My toilet had the same problem a few times. I managed to clean it out because the pipe is somehow connected to the downstairs drainage pipe in my house. What fixed the toilet clog was going to the source of the problem and pouring extremely powerful hair clog remover chemicals in it (I did have to open all the windows and get the pets as far away as possible and wear a mask). After the specified amount of time waiting, I went to go flush and it worked.

**Answer**:
I would recommend doing the same thing but only if everyone in the house is gone for 1 hour. Also I would air it out by leaving windows open, not first floor doors or windows though. It can be deadly if inhaled for extended periods of time. The more powerful the cleaner, the better the results but the deadlier it can be if inhaled. Try this.

My second guess is that it may be the plug inside the toilet's tank. You should check to see if it is working properly. Try flushing with the lid off and watch the plug to see if it is working properly.

follow this steps and fix it. God bless you

f the toilet bowl overflows, use a plunger or auger to eliminate clogs. If the toilet does not flush, tighten or replace the defective handle , adjust or replace the lift chain , or replace the flush mechanism. Jiggling the handle forces the lift chain or rod to re-seat the flush mechanism, telling you that something is awry.

If the bowl drains sluggishly, remove the clog with a plunger or auger, or raise the water level in the tank .

If water runs continuously through the toilet, lower the water level in the tank , adjust or replace a lift chain or wire , repair or replace a worn flush valve , clean or replace the valve seat assembly .

If water appears under the tank, tighten the tank hold-down bolts , lower the water level in the tank, replace the float valve , replace a malfunctioning ball , or tighten nuts on the water supply line, replace leaking supply line . As a last resort, re-seat the toilet .

If the seat is cracked or unsightly, replace it .

If the bowl or tank is cracked or otherwise unacceptable, replace the entire toilet .

For now, just hold the handle down until everything goes down, common problem with low water use toilets, You may want to take this unit back and get another one.

lift off cover and adjust =shorten length= between flapper and handle lever

Try holding the handel down for a few seconds each time you flush.

Check the water level inside the tank to be sure the tank isn't overfilling and spilling into the overflow tube.

Also check the flapper valve (the rubber valve at the bottom of the tank that sits over the flush hole and is connected to the flush handle) to be sure it is holding and not leaking.

Make sure the handle chain that goes to the flapper valve isn't tangled up and holding the flapper valve partially open.

This is how it is meant to work!
Short push of lever for small flush, push and hold lever for full flush.

I had the same problem. The fix cost me 50 cents (literally). I just placed a quarter on top of the Blue and White flush buttons (not sure of the technical terms) inside the tank and now it flushes properly. It seems that the 2 plastic poles the extend from the faux chrome buttons are just a bit too short.
Hope this helps

You might want to check the flush cylinder, to see if it has water in it. It has to be water free, that way the air in it, lets it go down easier, during fill up.
