Hi, did this get resolved. Did soldering the relay fix it.
I have exactly the same problem, start-up pump kicks in for 1 minute or so and is meant to stop when the second pump kicks in but doesn’t. Start up pump keeps on running unless unplugged.
I have changed the gates as one was sticking but still get the flow error on display panel.
Everything else works as normal, but I want to have all seats with jets.
