Hotpoint FDFF1110 Error A5

Before I start taking the appliance apart to try resolve this problem, could someone give me an idea as to where these would be located before I start taking it all apart.
Typically I believe this to be just out of warranty but cannot locate my receipt at present.

I understand from the error codes section that this means one of the following :
A05
A-5: Circulation pump blocked or faulty
Check filters
Check circulation pump motor for blockages
Check main circulation pump

All help greatly appreciated.

Thanks
