Nespresso Coffee Machine Descaling

missile

Hi,
We bought a new Nespresso Vertuo Coffee machine. Makes great coffee. The machine has a warning to indicate when descaling is required. The process is quite difficult. I took my time, following the instructions carefully and still warning light. Repeated the process and still warning. I contacted Nespresso who talked me through the process for a third time. They agreed to collect the machine and three weeks later it was retuned with a note to say they could find no fault.
Fast forward to today and the warning light is on again    
Once again I carefully carried out the descaling process per the instructions. The warning light is still on.
I searched the internet for others who may have this issue. I discovered that the descaling process must be completed within two minutes or the system resets to fault.
I descaled the machine yet again, using only tap water. I completed this within two minutes and warning light is gone.
Nespresso instruction book does it mention this piece of important information.
If any others have Nespresso coffee machine, hopefully this may save you frustration as and when it requires descaling.
