I had when I read my codes at christmas, but made no effort to check if it is still occuring or rectify it.

If it is easy to disconnect the power to that pump then doing so should cause an open circuit fault, indicating the short circuit to be inside the pump. If the faul remains then the fault is probably in the wiring.
