The contacts inside the time clock have most likely warn out. If it is coming on randomly it is not making good contact and will create arcing, which is dangerous. Call an electrician, they may be able to replace just the internals.

If you are getting voltage to the motor, and it still doens't work, you probably need to replace the unit.

You need to check the line voltage being supplied to the timer. It is possible that you have a reversed neutral and common (hot) line providing power to the timer. It is also possible to have another reverse situation with the way the timer is hooked up to the device it is controlling.

Timer motors should only operate in one direction, but if mis-wired, they can operate backwards.

I would need more information about the exact installation you have in order to provide a more thorough diagnois and solution. Info such as is this a 220V-AC installation; is the timer hooked to more than one (1) device (pump, etc.) ; Is there a GFCI breaker on this circuit (there should be!) ; Is this a new installation or a refurbished pool with a new pump & timer?

Please use the "comment" button to supply me with the info requested so I can better address your issue.

Thanks!

T104 timer is 240Volts.
Not 120Volt
You can convert timer into 120V by changing clock motor from WG1573 to WG1570. This action will convert the T104 into T103.

The T104 timer can be wired many different ways:

Add a comment with specifically what you are connecting to timer, and I will comment back with more detail as needed.

The problem is that you need a jumper wire to power the clock from one of your two hot wires (assuming the clock is 120V), because the clock is currently powered downstream from the switch built into the timer. The jumper wire needs to go from one of your hot wire inputs to the clock. Don't add a new wire, just move the existing jumper wire that is going from one of the output terminals to the clock, so that it goes from one of the input terminals to the clock.

Your 240V wiring is not described clearly, and it sounds like you are confused about 240Volt circuits.
You posted under T104R indoor-outdoor 240volt timer:
http://waterheatertimer.org/images/T-104-control-240V-Load4-35.jpg

Typically a 240Volt cable is 2-wire with ground, and does not have a 'neutral'
A neutral is not necessary to complete 240V circuit.
If your 240Volt cable is a 3-wire with ground, then the neutral connects to terminal A on timer.
Open following links for specific T104 wiring diagrams plus illustration of 2-wire and 3-wire cables, and illustrations and explanation of difference between 120V and 240V circuits:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
http://waterheatertimer.org/images/wire-ga-250.jpg
http://waterheatertimer.org/B220C.html

If you have 240Volt cable, then do not move clock motor wires.
The clock motor wires connect to terminals 1 and 3.
240V power from circuit breaker connects to same terminals.
Load wires connect to terminals 2 and 4.

If you are not getting 240V across terminals 1 and 3, then check circuit breaker.
240Volt circuit breaker can be tripped off on one leg, or bad on one side so you get 120V on one leg at timer, and then clock motor does not rotate dial.

Is the clock keeping time?
Was a new clock installed so that wiring was disturbed?
Ensure that it is wired to the line on terminals A & 1.
If the clock is operating, is the ON tripper installed properly, that is, hitting the switch to turn on
the load?
Do you have the proper tripper for your timer?
These are some areas that can be inspected.

Two hot wires from the panel go to "line" and two wires from motor go to "load". See the diagram on the inside of the door. You should consider running the "load" to a 220 wall switch and then to the motor so you can turn it off quickly if necessary without fooling with the timer.

The clock motor has gotten weak.
With Intermatic T100 series timers, replace WG170 120Volt or WG1573 240Volt clock motor for $20.

Couple of possibilities
1. make sure the clock motor is connected to the input line 2. see #1, but make sure the clock motor comes before the switch (so it's not running just when the switch is "ON")
3. ... and make sure the feed is always on

Did you forget to push the yellow dial back in? If the timer has been in place for a while and was working OK in the past, this tip may help:
http://www.fixya.com/support/r4722277-troubleshoot_problems_intermatic_timers_

If this is a new installation the timer is mis-wired. The incoming 240 volt wires from the circuit breaker (or source) _must_ be connected to terminals 1 and 3 because the clock motor is also connected internally to those terminals. Read this tip:
