I followed what everyone else had made reference to and to my fiancee delight, the machine is working again. I think it is worth noting though that it is important to tilt the machine backwards and place a bowl or bucket underneath the bottom right corner. in our case this meant pulling it out from within the built in unit. this way you manage to avoid a lot of the water getting on the floor. Also, we thought that if we just turn the plastic Bung a little and let the water trickle out, we could then gradually turn the bung more allowing a greater flow, however just be warned that once the water is coming out at a good flow rate you won't be able to tighten the bung back up and you Will have to wait for all the water to have drained. Didn't really find anything stuck but the process has worked so great, thanks all.
