Truma problem (1 Viewer)

[goldenline]

Have just bought a hymer 644 swing and tried the water and hot air systems before we set off for home in France everything worked fine. On route we found that the water system
stopped working to the toilet and taps,but found that there is an overflow from the trauma boiler and when we opened taps or flushed toilet the water came from the overflow. Just wondering if anyone else has experienced a similar problem.Any thoughts would be appreciated
Thanks

This 'overflow', is it on the van side, a small outlet next to the Truma air inlet???

Hi
The tube exits the van just under where the heater is situated.Could it be an air lock?

Try this, from a friend.......:thumb:

Check the non-return valves there will be at least 2 one in line with the cold feed to the boiler & one in line with the loo (this one shouldn't have any effect on the problem) there may be one after the pump.
Also check for a kinked pipe it doesn't take much to reduce the flow at the taps as the pumps aren't very powerful.

Has the anti frost valve opened? this dumps the water to avoid frost damage.You can simply pull the lever up -usually red or yellow-- it should stay up but if the fuse has blown it will remain down/open once you let go --of course I could be on a different thought wave Just re read your post and it does not sound like dump valve but worth a check

It sounds to me like your anti-frost valve has opened and dumped the contents of the boiler. When you switch on a tap the pump starts and pumps the water straight out. It happened to us in the middle of summer when it got accidentally knocked by a tin of beans (ours is in a kitchen cupboard).
