Getting cold water from hot side of faucet.........water heater 'bypass' valve is still open.
3 valve system......bypass is one on red/blue line
2 valve system......bypass position shown (valve handles pointing in direction of flow)
Different 2 valve system.....bypass is one on red/blue line
1 valve system......bypass would be if valve handle was pointing up

CLOSE bypass
