hey peeps,
my boiler (not the wife) has packed in, any experts out there?
its an instant gas water heater, powered by one of those small repsol orange gas bottles. the light is not coming on, but the batteries to power it have just been replaced. gas is fine as its working in the cooker.
when the hot water is turned on, nothing, no spark, no igniting...
its a junkers by bosch make. i've looked inside, no stray wires, or anything like that.
cheers, hopfully, in advance.
ps, yes we are therefore smelly today

One suggestion I have is if you have power from the batteries and there is no spark or the digits do not function then look at the water pressure. There is a filter inside the heater take this out and clean it.
HTH

hi- batteries are fine, but no life at the on/off switch at all (i know that this light flashes when the batteries are dead, happened a few moths back, but now ones re-installed today anyway) no spark at all, water pressure is not great, but no worse than its been.
where abouts would the filter be?
cheers

Where is the filter? It is difficult to explain, if you follow the water inlet pipe it is located where that pipe joins the body of the heater. This pipe is usually a flexible pipe.
It is illustrated in the instruction booklet. If you do not have one then you can download it from Junkers web site. I don't think there is an English version though

hi- ok, i can see where the cold water pipe hits the heater, around where the temp control switch is, so is the filter 'filtro de agua' in the diagram, sort of looks like its right where the water pipe connects?
thanks for the help incidently.....

thats ok.. I am off to bed now so you are on your own until tomorrow

Has the boiler been left unused for a period of time?

digdug

nope, ran out of gas on wed morning, picked up a new bottle today.

As CSE said it may be water pressure, try opening two taps at once.
If it ran out it may of got air in the gas pipe and will take quite a few attemps to light before the gas gets through unless you purge the pipe.
If it is still under the two year warrenty call the service dept and they will send someone out to fix it.
We had the same problem intermitently, first time he said it was an airlock, but just after he left it went again.
He returned the next day and put a new bit in the control box and it has been perfect since.

Who...are yes us. Sorry it is early in the morning! So how did it go Double D?

digdug

hi all, just got it sorted. i rang an explumber, who insisted the heater would have a trip switch somewhere, 10 minutes of hunting found the wee git - working like a charm....

thanks all - off the de-smell!

Trip switch? where is that....not for us but some friends who have a similar heater. We still have a reliable non electrically controlled water heater.

right at the bottom (you dont actually need to even take the cover off).
on my model, theres a black plastic arm about 3" long connected to the bottom of the metal unit. on the bottom of this are is a wee round cover, just pop it off, and theres a push-in switch, using a screwdrier. hey presto!!hope this helps.

thanks for the info. It may help our friends if they have problems as their house is a holiday home and they disconnect everything whilst away.

Make sure you get gas boilers serviced regularly, and keep your eyes open for any fumes coming back into the room.

Monoxide is a real danger.

Me, I plan to set up a solar system with electric as backup.
