The LED display will display the hour (1-12) and on the half hour a light will illuminate in the upper right corner, next to the number 30.

1) Copy following links to identify timer, and download possible manual:
http://waterheatertimer.org/Woods-timers-and-manuals.html#13660
http://waterheatertimer.org/GE-timers-and-manuals.html

2) After programming is complete, press clock button to start timer programs at next set point.
It is not necessary to push Mode button. Some people report that Mode button is problematic with these timers.

3) Add comment and include photo or detailed description of timer for possible identification of timer, and possible manual

If you need further help, I’m available over the phone at https://www.6ya.com/expert/gene_9f0ef4df2f9897e7

I don't have repair for defective timer.
If following information does not apply to your timer, then add a comment with clear description of timer for possible help.

1) The only complaint about this 6-button timer sold by Woods, GE and Westek is the MODE doesn't work.
The key to this timer is to finish programming, and then press Clock to return to current time, and at this point the timer is in correct mode.
Then do NOT press mode button ever for any reason, except to reset timer.

2) Try resetting timer by pressing Clock Mode and Prog buttons at same time, and then re-program timer.

3) Timer is not heavy-duty. Load rating is 1000watts incandescent, and 1/4 HP.
If load rating is greater, then timer will not operate as expected.

4) If you have problem with timers, try timer on different load and on different outlet.
Test outlet for polarity using circuit analyzer.

I cannot repair defective timers, and there are complaints about this timer's MODE button.
Most people complain they can't get mode to set.
Avoid the MODE button after programming timer.
Reset the timer by pushing CLOCK PROG MODE buttons. Then re-program the timer per instructions, and then press CLOCK button to exit programming and timer is in Auto mode and ready to work.
No need to press MODE after programming timer.
Typically, this timer has limited 1 year warranty.

15117 is not heavy duty timer. Both outlets combined are rated 1000 watts incandescent and 1/4 HP. Check nameplate on your pump for HP rating.

For limited-lifetime-warranty timer, rated 1/3 HP, choose Intermatic HB800RCL 2-outlet timer.
Cost twice as much as GE 15117.
For 1HP outdoor pumps choose Intermatic P1121

Easiest solution is to buy two separate timers.

GE does not have 2 channel plug-in timer. Nor does Woods, UPM, Swilight, Sylvania, Tork, etc etc.
http://waterheatertimer.org/GE-timers-and-manuals.html

Zilla has a two channel power strip where one channel is for 12 daytime hours and 1 channel for 12 nighttime hours. The yellow outlets power daytime hours and blue for nighttime. You can adjust current time so the hours can be whatever, but the 2 channels are strictly 12 hours each and do not overlap
http://waterheatertimer.org/GE-timers-and-manuals.html#zilla
Your time schedule doesn't fit zilla

You need a 2-channel timer which takes you into more expensive territory ($150-$300), or just buy two separate timers since each load has to operate independently.

Intermatic make 2 and 4 channel timer:

The Nordik TM-065 timer looks similar to Woods/Noma N1506

Plug timer into outdoor receptacle.
Press Time button until correct time displays.
Dot on display is for pm hours
Nordik appears to be on the 24 hour clock instead of am-pm

Set operation of timer by pressing Mode button.
P flashes for program mode.
Press time button until starting time displays.
Press Mode again and E flashes.
Press time button until finish time displays
Press Mode button to exit programming.

GE 15117 manual

You might try a new AA battery.
Some guy wrote in this week and said he bought 6 timers and all the batteries were bad except 1.

Some timers, like Woods TD1300, and others have the 12 hour or 24 hour option.
You press and hold Time button to choose 12 hour or 24 hour
But GE 15117 manual says nothing about this option.

GE 15117 timer is same timer as Woods 59403
Several folks have written in past couple weeks about the Woods 59403 timer skipping over functions.
The best I can guess is your timer is malfunctioning like the other people's timers.

Woods 59403 manual is identical to GE manual, and says nothing about 12 hour 24 hour option either
http://waterheatertimer.org/pdf/Woods-59403.pdf

I test timers for programming and wiring difficulties.
Yesterday 3 timers arrived here, and 1 didn't work.
I took it apart and tested the electronics, and something went bad.
When these timers don't work, you get your money back or throw them away.
