I have this on my pull button

#showtooltip Summon Water Elemental
/stopcasting
/castsequence [target=focustarget] reset=144 Summon Water Elemental, Cold Snap
At times this does nothing, even if the Water Elemental's CD is up.
Try removing the reset or lowering it? If you're hitting your pull button again before 144 seconds are up, you would run into issues where you're restarting the timer and nothing will go off because it's stuck on waiting for the coldsnap timer to progress. If it can't reach the end of the macro because CS is still on cooldown, it can't loop around to the start of the macro to pop the WE, and it can't reset because you told it to wait 144 seconds without any action in order to clear its' status in the macro.
Try using:

/castrandom[target=focustarget] Summon Water Elemental;
/cast Cold Snap
