Mend Whirlpool WMA36 Washing Machine Drain Pump PCB

wma 36 wont drain on end of wash cycle?

Help. My wma36 stops at the end of the wash cycle and displays all lights - wash/rinse&spin/final spin. I checked the pcb and found one of the tracks that outputs to the pump to be burnt out. I got a new (2nd hand) board but it made no difference. The pump works fine as i've hard wired it to the mains with a couple of spade connectors so I can switch it on and off at will to drain the machine. If I time the draining right the machine completes its cycle correctly incl. rinse and fast spin. What causes the pump not to get the signal to drain - I cleaned everything out but to no avail. I have been told by the person that supplied the board to totally remove and discard the ping pong ball. Any suggestions would be great..

when looking down on the board to the left of middle there is a series of 3 plugs side by side, 2 of the plugs have only 2 wires one is black x2 the other is blue and black. the 2 blacks (press sw) should be furthest left and positioned at x9

I'm about 99% sure they are right, which leaves a bit for error! Any idea where I can doubl check where they go?
cheers

very easy to mix up the plugs when changing the board. Are you sure you put them on correctly as this fault will occur when they are wrong?
