How to replace the Water Pressure Sensor on Vaillant ecoTEC Pro 28 ?

My Vaillant ecoTEC Pro 28 died yesterday and it showed a fault code f73. Tracing the code on the manual I found a few lines about it, one of them says the water pressure sensor but nothing about how to take it out or change it. I know loads of you guys out there know how to do it. Tell me please, please, please.... Thanks.
