Beko washing machine stuck on wash phase

I have a Beko brand washing machine, model number 'wmb 51021', and very recently has a issue where it get stuck on the 'wash' phase (second phase after starting). The machine goes on for hours washing, and seems to never end. Using different heat settings all have same result.
Works normally when using Quick wash setting.

Any ideas what might be the cause? Machine 2 years old.
