Supajet 101 problems also,
I cant answer your problem but Im having trouble with a Supajet 101 . I thought it might have been the flow sensor - a post told me to remove 1 connection to the flow sensor and turn the water on - if it pumped this indicates the flow sensor is faulty. It did not work still.
An electrician friend then said to take a 12 volt power source (car battery or battery charger) and to connect it to each stage until you find the problem - ie. in place of the transformer and directly to the pump terminals. I disconnected my transformer, connected the battery charger instead & turned the water on- it worked. Hence I have a faulty transformer (£80 bl**dy quid !!).
Your problem may be the pump - just connect a 12volt source direct to the terminals to see if it works.
