Samsung washer strange WE90K5410UX/EU

Hi,
This washing machine has a weird fault. Start a program, it fills with water, drum starts to rotate then it stops and just sits there. Time doesn’t count down. If you press pause and then unpause it it will start again for a bit with drum rotating then stops again. It’s like a brush problem but brushes all good and it’s strange it starts after pausing. Seemed to work on spin. Draining, heater all checks out ok. Motor has slight lower insulation but still well in the megger ohms.

Any ideas?

Thanks
