Can you email the pictures to firstname.lastname@example.org.
It would be particularly handy if there are pictures of the pump as opposed to the control module as that was fitted to a few different pumps.
It could be a faulty non return valve in the control module if the pump is cycling on and off or it could be something on your system activating the pump. You need to have an isolation valve after the module. If you have one shut it down and leave the pump
as long as possible and see if it still cycles. If it does the control module is faulty but at 10 years old we would recommend replacing the complete pump, once it's identified.
