I have a 3 month old Wunda 9 zone manifold with a Grundfos pump connected to the the wiring centre. It has been working fine until recently when the system stopped working and it turned out the pump had a fault. The pump was replaced and worked for a day and now the new pump seems to have blow too. There is hot water as far as the pump but nothing is getting through and I suspect this isnt just a pump problem. The lights on both pumps stopped flickering and didnt power up after I flicked the power. The pump does have power to it as ive checked the cable for volts
What could keep blowing these pumps? A few hours before the lights went out on it tonight the system stopped working and I was trying to figure out why it wasnt flowing.
Im lost and my plumber hasnt a clue
