Mend Vaillant Ecomax 824 Fault Code Low Pressure

Where is the water switch- Vailant Ecomax 824-Fault code F25?

My Vailant Ecomax is showing a fault code of F25 (water switch - low pressure) I have checked the pressure which looks fine but I cannot identify the water switch, where is it or does it have another name?
