I have a compass caravan fitted with a truma crystal filter and a submersible pump. When the taps are on the LED lights up on the ZIG unit to say pump running. the pump sometimes will run for about 20 seconds then stops, then will run no more. I have checked that there is 12volts at the pump connection (back of crystal filter unit) when taps are on. The pump works when connected to an independent supply. As soon as the pump is plugged in the 12 volts disappear. Any ideas would be gratefully received. Thank you.

I have a Truma S3002p. It goes out, but at no particular time or pattern. have sat and closely watched the blue flame stop, if i press the piezo quick enough it relights as the thermocouple is holding the valve open. i am Gas safe LPG etc and have thrown new parts at it, valve, thermocouple, burner, 30mb jets, electrode, the flue and cowl are spotless. The alloy casting was washed out with gallons of water, no sign of a blockage, gas pipe purged (aggressively) and of course a full bottle, It is a second-hand swift 2008 sportstyle 2. only had it 3 weeks but seems so very much more. please HELP !

1. I think we have a problem with our Gas Regulator part number TRuma 0129411. I see from other queries a problem with residues blocking the regulator is a regular problem. We have tried two different gas bottles we know have gas in, and no gas is getting through to appliances, hence we think the regulator. Does this seem correct. 2. Buying a new one - we cannot find this part number on the TRuma web-site or yours. Are the new replacements all with an elbow? 3. Should one fit a filter as well?

Hello Tom, I have a van with a Truma c6002eh heater, it has been playing up for a week or so before finally stopping altogether, can you tell me this, although the air circulation fan turns as soon as switched on, I have taken the combustion fan out to check that, despite a 12 volt supply reaching it, when the boiler is switched on it does not turn at all could this be the reason the boiler does not attempt to run, many thanks.

Hi,
We have a 2003 Lunar Solar 524, we can get our trumatic fire to work on electric but have no idea how to work it on gas. We have tried pressing the ignition etc but nothing seems to work. We've searched everywhere in the van to see if there is maybe a valve we should turn on, but can't find anything. Also, the ignition doesn't make a noise when we press it.....should it not sound like its sparking etc? All help is greatly appreciated as we are new to caravanning.....thanks in advance.

Hi I have a truma ultrastore gas and electric hot water boiler/tank 10ltr today the red light came on the controller as if to say the gas has run out. So I checked the cooker in the van and all burners worked so there is gas in the bottle. The problem is gas is not going to the truma boiler. I can hear the ignition working but it will not light. Its only happened today been using without any problem for 1 month. Any idea what would cause this. I had a friend turn it on whilst I put my nose to the exterior vent and I could not smell gas, just the sound of the ignition. Hope you can help. Thanks in advance.

Hi. I have a Chausson Motorhome and note that the gas pipe is 8mm black plastic coated steel. Are the standard fittings e.g item 126863 compatible? Do you supply suitable gas pipe to connect from the manifold to a Truma barbeque point? I have an available take off point from the 4 tap manifold as the grill has been removed and replaced with a microwave. I am not sure about the compatibility of copper pipe to this manifold as everything is piped in steel and would prefer to keep it the same. Rest assured any changes will be checked and tested by a competent person. Thanks

I have a 2005 Hymer Freetec 582. Every time the temperature drops below 4'C the boiler drain valve operates and drains the boiler - as it should. Unfortunately it also completely empties the fresh water tank, which according to the hand book "all other parts of the drinking water system remain filled". For a winterised motorhome that we intend to take with us for winter skiing it is obviously a problem if each day we leave the motorhome to ski we are going to return to a completely empty freah water tank.
