Washing machine has suddenly started pausing mid cycle - WF80F5E0W4W eco bubble 8kg

Machine has been brilliant until just started doing this yesterday....I thought I had accidentally knocked it and when I pressed start/pause it fired up again?!

I cleared drain this evening and recalibrated the machine but problem still persists. 

Can anyone shed any light on this issue for me? I could really do without the expense of an engineer while I am furloughed 😕
