If this does not work I would open the 3 pumps and inspect them for any blockage. I would do all testing without the 7097 connected and this means no din cable connected at the pump. The simple possibility would be that the 7097 night mode was on or a setting shut off the 3 pumps but if you disconnected the din cables at the pump and the 7097 is disconnected that would rule this out.

Thanks for the suggestions, the power supplies seem to be fine. The working pump continues to work with all the PSU's.
I haven't taken them to bits yet, but would be a big coincidence for all 3 to go within 40 min.
That said, wouldn't rule it out
