Hotpoint Fdd912 dishwasher a7 error code

I will try and help with your Hotpoint Fdd912 dishwasher

I cannot find an A7 error​ code​ but F07 is a fault code​ and means you have a fill problem normally with the water turbine  - it may be damaged or blocked, I have included a video below  but it explains how a turbine works and is sometimes called an impeller jug
