Our next fix will be to replace the pump with last years. Any other ideas??

Check your main robot battery. As the voltage of your main robot battery decreases, the amperage of the current traveling to all your electrical loads will increase. (E.g. Watts = Volts x Amps). This increased amperage is usually what blows the fuse on the Spike relay.
Replacing your main robot battery with a fresh one should take care of most of your issues. 
Edit: Oops, I forgot Ohm's Law.
