Central heating timer fault or something else?

[Gary Colclough]

Noticed that when we turn the heating on manually we would then notice it had gone back off again so set to continuous and saw this

video has sound

Does this look like a faulty timer or something else tripping it?

Thanks

Does look and sound like the programmer, but could be a loose wire?
