Ben two years ago we had to replace our pump - aparently the actual cog inside the pump is plastic, both the male and female parts, this means that in time they simply disintergrate. I'm now having the same issue again, so of course I'm wondering whether we have to raplace the pump again, might be time for a new brand of machine quite frankly.
Did you manage to find any more out on your end?
