    We are just getting ready for our first outing this year and Mike has filled up with water to check the heating and water.

    Unfortunately, the taps are on, the water is in but there is no sign of the water pump working.

    We have located the fuse, which was blown, and replaced it but still no sign of the water pump kicking into life.

    Any advice please???

    Check fuses or give the pump a tap with a hammer if you can see it, might be stuck

    Is it a submersible inside the tank?

    Cheers

    you Need to remove the panel that you move to get to the drain tap and there is a large screwed cover and the pump is at the bottom of the tank.
    On the Possle forum I’ve seen pictures of the pump melted, I now carry a spare pump bought from EBay.

    Yes it is in the water tank, so that’s first problem solved. Where did you get your new pump John, and can you give me the exact model please??

    Do you think we could exchange it ourselves or is it a job for the professionals?

    We've experienced a similar problem with our submersible pump on our Rapido pvc.

    Advice from this forum resolved the problem. We unscrewed the top inspection cover for the fresh water tank and reached inside to grasp the pump. Whilst the tap was switched on I banged the pump on the side of the tank to break the airlock that had presumably formed. It worked!

    No idea if such action would solve your problem, but it's worth a try. The issue for us arises after the tank has been drained down and the pump dried out.

    This is the pump which is fitted, could this be a replacement, it doesn’t seem very powerful.

    Water pumps are a constant source of problems - just do a search on here.
    You won't notice a difference between 19 or 20 ltr.
    If you go Reich make sure it will fit through the hole in your tank.
    To replace is easy but you will need to expose the electrical connections which may be behind furniture - just depends where the tank is.
    Carry a spare - lots of people do - but then I was a boy scout.

    I would try & stick with the Comet as a replacement. The higher pressure of the Reich could be a recipe for leaks when showering. When you stop the flow with the showerhead trigger, the pump will raise the water pressure in the pipes to 1.4 bar when Globecar were only expecting 1.1 bar. So long as you are happy with how fast the water comes out of the tap, the lower the pressure, the better.

    If the fuse has blown, I suspect the pump has seized, rather than it being an airlock issue. Can you hear the pump running when you open a tap? It is possible that a sharp tap may free a lightly seized pump, but less likely. Well worth a try though. But even if you manage to free it off, carry a spare. If it's already seized once, you are almost certainly on borrowed time.

    Well we banged it on the side, still no water but there was a nice smell of burning, so accepted that the pump was broken.

    Many thanks to Terry who has recommended a dealer in Barnsley, so we are on our way to pick one up now.

    We bought a spare identical pump from Amazon. I know some people fit a non submersible pump which may be a route we go down ultimately ...

    Our Globecar is fitted with the Reich pump as standard.

    That’s interesting John, Mike has always complained about the strength of the shower - he calls it more of a dribble! Maybe the Comet was put in instead of the Reich. I’ve tried to find which pump was fitted originally but no joy as yet.

    We have bought the same comet pump, but if I can find which pump was fitted originally we will buy that as a spare.

    just a thought, if the old one was giving poor performance it may be wired in reverse. this would match those symptoms plus globecar install a reich pump as standard I believe. both pumps are similar in output and either can be used
    german wiring confuses people as they often use blue for live

    Hi @Teasy2007 our shower and wash hand basin tap hasn’t the same flow rate as the kitchen tap.

    My Campscout dates from 2013. I'd have to go & fish to see exactly what the make & spec of the pump is, but it certainly looks more like the Comet than the Reich. They may well have started fitting the Reich to later models.

    We have a 2018 Campscout with the Comet fitted by Globecar.
