Autocruise Startrail Water Tank

[Connie]

We have just taken our Autocruise Startrail 2009 motorhome from storage and discovered a few problems ~

 

The Control Panel lights remain permanently lit, they should turn off after thirty seconds

 

Also, a warning on the control panel says - Water tank reader failure - the fresh water intake on the control panel is actually showing that is is only half full when we know the tank must be completely full to its maximum capacity because the water was in fact overflowing.

 

Additionally, the water when heated via the Truma Combi 6 is lukewarm.

 

Any help would be greatly appreciated.

Did you run the water pump to fill up the boiler first before you turned the heater on?

[Connie]

Yes we filled the boiler first. I failed to mention this problem occurred using the electric hook up, we haven't actually tried gas only yet.

 

Thank you for replying.

Check any wiring underneath around the areas of the tank and water heater for any signs of corrosion or damage.

The connections may have corroded with the damp whilst in storage over the winter or just may have been the victims of rodent damage depending where you store it :-(

I note from your previous postings that you have owned your Startrail for at least two years, so I’m reluctant to suggest you might still be unfamiliar with its Truma Combi 6E heater.

 

This time of year domestic freshwater will be pretty cold, but a newly-filled Combi 6E should be able to heat the water inside it to 40°C in, say, 40 minutes when the heater’s 'Summer Operation (boiler operation only)’ 230V 1800W setting is chosen.

 

If one were to select 'Winter operation – Heating with water temperature monitoring’ and the heater’s 230V 1800W setting, as air heating would also be taking place, water heating would be much less efficient and even after, say, 40 minutes the water might only have attained a lukewarm temperature.

 

I suggest you try the following:

 

Select the heater’s 'Summer Operation (boiler operation only)’ 230V 1800W setting. Choose the 40°C water temperature setting. The orange light on the heater’s control-panel should now illuminate. Keep an eye on the orange light, which should be expected to stay on for 30 to 40 minutes. When the orange light goes out the water in the heater should have reached 40°C.

 

Now run some water from a hot tap. This (as one should expect) will be cold to begin with but should soon run hot. If the orange light does not go out, or the orange light goes out very quickly, or the orange light goes out after 30 to 40 minutes but the water from the hot tap is no hotter than lukewarm, it must be assumed that there’s a problem with the heater.

 

I’m not sure if this (long) earlier discussion will help, but it has a broad scope.

Vehicle electrics can get uppity after prolonged non-use in cold damp conditions. Try running the heater on gas for a while and use the heater’s blown-air capability to get the motorhome thoroughly warm inside. Keep everything warm for a while and you might find the present problems cure themselves.
