Hadn't used the spa for 6 months or so and when starting the jets the safety switch is tripping.
Last time this happened (approx. 2-3 years ago) I noticed a small water leak where the pump joins the pipes, and replacing the o-ring stopped the leak and the pump continued working.
This time, again a small water leak so replaced the O-ring. Leak is fixed but the pump is still tripping the safety switch.
Is it toast?
Or is there something else I should check?
Pump is an Edgetec Triflo like this one: https://www.spastore.com.au/edgetec-triflo-1.0hp-auto-heat-air-switch
