A hot water heater problem not electricity problem

Fee

Hi, I have a hot water heater problem and need opinions. Any comments or clues will be welcome
I tried to fix a leaking problem of hot water from the kitchen faucet. I shut off the inlet main water valve and the valve under the sink. As the water should be completely stopped at this moment. But when I removed the cartridge from the faucet the hot water still runing out of the faucet. Why did this happen and what is the possible cause?

Thanks so much for your opinion for this matter.
