fault with my Hotpoint aquarius + (WMF760)?

I have a fault with my Hotpoint aquarius + (WMF760).

The fault:
When the machine gets to the last 5/6 minutes which is the spin cycle function an error comes up F11 and you can hear the drainage pump constantly draining.

What I have done to try and fix this fault:
• Checked the wiring near the drainage pump etc and all looks ok
• Removed and cleaned all drainage pipes including the filter
• Checked the drainage pump is working ok

I am out of ideas, except for trying to reset the pcb/fault but as the machine is always on pause I cannot get this to work even if this might correct the issue ?
