Anova SV tripping when plugged into Energenie energy monitor.

Wanted to drill down on items energy consuption, so plugged in the 3150 watt capable Energenie monitor which works fine with ASHP tumble drier, kettles etc (uk 220-240v) but the anova is hating it & tripping out, not fusing, however its display is fully lit up.

Why is this? common sense logic clearly eludes me.
