GC Water Pump Down

[Pwee]

We are away on our first longer outing in our 2023 GC 600. We are now seeing a couple of the long known quirks and glitches of the van. Two days ago I added a post on heating and hot water drop outs to an existing thread. Mr T kindly confirmed the temporary workaround and am now booking in with the dealer. However yesterday morning the water pump stopped. Nothing to be had at the sink or bathroom. No sound of a labouring pump just now you have water, now you don’t. I have tried a reboot of the control panel using the red switch with no joy. This looks to be another recognised problem but is it one like the heating one, now with a VW TPI or identifiable solution? Is there anymore I can do while on the road please, as the trip is getting more interesting for the wrong reasons and need a site with all the facilities?
