Nespresso Repair leaking

How to fix a Nespresso Magimix Coffee Machine that leaks water into the Capsule Box every time you make a coffee. Replace genuine parts for a fraction of the cost to send the machine away.
Nespresso were not interested in replacing my machine just a few weeks out of warranty. I had never used any other make of capsules other than genuine Nespresso ones, and they wanted €90.00 just to LOOK at it, my repair was less than €40.00 and 20 mins of my time. Simple repair that anyone can do for a very common issue.
