Pool was buildt in 2001.
Pump is Hayward 1HP Model # K8L2N105;
The time is T104R Intermatic 208-277 Volts 60 hz

Last night went to turn the pump on manually and nothing - Manual switch and the timer is not working. The time dial has not moved.

I have checked the pump and can not see any wire problems.
Hit all the resets - nothing.

I have power to the timer, so Im assuming the timer is dead.:confused:

Cna you confirm a full 240 volts at the timer? Poiwer could be just 120 if you lost a leg

Confirm power at Line and Load side terminals, if you have power on Load side and pump doesn't work, it is the wiring between timer and pump or pump.
If the timer doesn't advance, verify power to line side, if you have power and timer doen't advance, just change the Timer Motor. Bring old one in as they have a couple of styles of tomer motors.

Balle is correct. If you are only getting 115 volts to the timer then the times will no advance since it is 240 volt.
You might not have a good connection to one of your legs. Check both legs (Electrical that is.)
