Warwick XL Water Pressure Switch

Does anyone know where the water pressure switch is on the newer Warwick XL's? On my previous with the Truma system it was easy to find. 

This van has been easy to fill tank from scratch with no adjustment required and little air in the system. Usually up and running within seconds after filling tank.

For some reason, this first fill after draining down for the winter, the pump just will not switch off. I can't see that there is any air left in the system. The pressure switch is my next port of call

Sounds more like dump valve open, ithink I have read that this is a yellow switch u der a hatch beneath nearside sofa, hopefully a someone with Whale system will be able to confirm or correct this.

Yes, I originally left the dump valve open and that was my first thought. Dump valve closed now, refilled. Still no joy

All sorted!! Found it. It is a lot smaller than my last one. Slight adjustment - in fact it's gone back to more or less where it was. I can enjoy my weekend away now

I don't have Whale but I believe the pressure switch is on the reverse of the water inlet socket but hopefully someone with the Whale system can confirm (or not).

Posts crossed, so where was it?

It was in more or less the same position as before - forward underneath the off side bench seat, more or less in isolation. There was nothing surrounding or obstructing it. I don't know how I missed it in the first instance
