Whirlpool washing machine AWM5145/5 wont drain

Hi,
My whirpool AWM5145/5 washing machine, Model number 857051415590 has developed a fault.
No matter what cycle you start it on it stops between the 10 (Silk) and A (rinse and spin) cycles. It wont move to the next programme & wont drain at all even if you put it directly to D ( drain ).
Ive cleaned the drain hose that runs from the drum to the motor and cleared all blockages / rubbish from the drum and other hoses.
Ive also now replaced the drain pump with a new unit but it still stops at the same place and wont drain or run the spin programs at all.
Any help appreciated.
Mark.
