Whale heater

Post by Rudi's Mum on Mon Apr 17, 2017 11:48 am

We are on our first trip in our 2013 Topaz since the habitation service in February and I've noticed that the red light keeps flashing even though the gas is not switched on- neither are the controls.  We normally use a small electric fan while on hook up. Any ideas please as due to my husband having had a stroke I am the driver and not very technical.

How many red flashes do you get before it pauses and then repeats?

Have a look at pages 22 and 23 of this :   

https://whalepumps.com/rv/siteFiles/resources/docs/resource-library/SHgas_electricinstructions_181.175_v1_0411.pdf

I'm not sure it is the correct manual for your model, but it refers to "gas lock out " and a red light flashing.. I suspect that if you turned your gas on, then ran it on gas for a short while then turned it off, that your red light may go out.... It seems to suggest that the red light indicates that there is air in the pipework eg following a bottle change...  We had a Truma heater which did much the same...

My understanding of a " gas lockout " is that the system is sensing air rather than gas in the pipework, so is disabling the gas side of things, and flashing a red light to let you know ..


Quote from page 23 here :-

Gas Lockouts Gas lockouts must be cleared by turning the selector knob from gas on (flame) position to off position then back to the on position. The complete sequence of switch movements must be completed within 2.5 seconds for a lockout to be successfully cleared. If there is air in the gas line, e.g. after a gas bottle change, the space heater may require several attempts before it lights. Lockouts can also be cleared by switching to the ‘fan only’ position and then back to ‘on’ within this 2.5 second period. Other Lockouts If the lockout is caused when the unit is operated on electric, the lockout can be cleared by turning the selector knob from electric ‘on’ position to ‘off’ position then back to the ‘on’ position. The complete sequence of switch movements must be completed within 2.5 seconds for a lockout to be successfully cleared. Note: A cycling of the power supply to the unit will not clear a lockout. Some gas lockouts, e.g. ignition lockout and combustion air faults will still permit use of the appliance in electric only operation.

It is saying - Sorry, I cannot light because my flame is going out - perhaps becuase of no gas (your case) or because of insufficient air (if the cover fitted to the outside of some older flues has not been removed.

Thank you so much Justus 2, I really appreciate your help I switched the gas on and switched the control on an off a few times and the light has thankfully stopped flashing.

Thanks also to Inspiredron,

Sue

Hi Sue
Just noticed this thread. It will happen again for sure, specially when you use the van for the first time in a while.

I know it's impossible for air to get into a sealed gas system, but it does!! Our fridge is the worst. I sometimes takes ten minutes of re-trying before it will stay lit, and even the hobs are sometimes stubborn.

Just keep at it, and once you have purged the pipework and the pure gas is getting through, it will be OK.

ALWAYS when you have changed a bottle or when the van has been left for some time turn off the fridge, then turn on the gas and light a gas burner.  ONLY when that is burning well turn the fridge on.  The fridge wil then light within seconds!
That is my experience.  up!

It happened to me also last weekend. Remedy is as other forum members have said above & explained in some detail in the A/S Manual. Gas lockout, switch the control on & off.

Thanks all, brilliant forum.  I was totally puzzled as I hadn't switched the gas on and hadn't attempted to use the heater

Hi,
To cancel the light you just switch it on and off again within about three seconds.

Hi

I had this error in the Topaz since new. As said to cancel switch on and off. I also turn the thermostat temperature dial to full on when not being used. I get less errors doing that.
