I'm a newb to this whole pool owner thing so please be gentle
My new house/pool came with a T104-70 Intermatic timer on the pump (a Hayward 1HP Superpump). The previous owner had no trippers on the timer so I guess he just turned it on/off manually. I've installed a couple of sets of trippers (two blocks of time) and I used the green "on" trippers and gold off trippers. The timer is functioning (mechanically speaking) - the dial does turn and the pump is turning on and off when the trippers contact the switch. But each time the pump is turned on and off, the dial gradually pops out such that it stops rotating and the trippers no longer toggle the switch. This can happen in as little as 2 or 3 on/off cycles. Pushing the dial back in will get it working again.
I've asked google about this and haven't found a similar situation. Does anybody know why this is happening and if there is a simple solution? I'm considering just replacing the switch but it seems like there should be an easier (and less expensive solution). I've tried swapping out trippers to no avail...
The switch should be no older than 2002 or 2003 based on the age of the other bits.
Thanks in advance!
