Ok, this is weird...

Hi,

Ok, so I was just in the kitchen about to make pancakes...

Supply Type: TNC-S - 100A BS1361 Type 2
Main Earth: 16mm (Polarity confirmed and external earth etc.)
Bonding: Gas and Water 10mm (Continuity verified)
Tails: 25mm
Consumer Unit: 17th Edition, dual RCD, everything is RCD protected

Cooker: Free standing gas oven and gas hob, wired into cooker plate at rear of oven, controlled by old wylex cooker control unit. Ignitor and clock only.

Ok, so this is what happened, I turned the knob on the gas to make it come out...

I pressed the sparker, then beep beep beep...

The Mrs and I think, what the hells that?

Hmm, I said you press it and ill look...

anyway, a new toy from the kids birthday the other day, it was literally just touching the radiator pipe.

Now the toy is plastic ok, see photo below, and this is it touching the pipework.

The beep beep beep is the sodding toy, no way, I don't believe it you say, well its only a calculator that looks like a cash register.

Hmm, whys it doing that? scratching head...

I move the toy, the beep stops, I move it back, press sparker thats on the oven in the kitchen, and sure enough its beeping again...

Ok, so I have absolutely no idea whats going on, its like there's some kind of static build up onto the pipework or something?

Any thoughts anyone?

Yes, why are you making pancakes this time of night?

Doomed · Sep 2, 2014

Is it a standard electric igniter that builds up a small charge to generate the spark - the sort that can emit interference at some frequencies?

telectrix · Sep 2, 2014

have you measured the voltage them igniters kick out.? it's enough to wake even geordie.

because he is hungry all right.

like a lot of members here he doesnt feal comfortable discussing his weight problem[emoji1]

so that's what he uses the drum for..... making pancakes.

Sometimes people get the munchies.

I fancied pancakes ok... LOL. I rarely eat them and had an urge.

I was thinking of getting the tester on it tomorrow if i get chance, but it was just making me think, is there some voltage in the pipework that shouldn't be?

Incidentally, the cooker kept relighting its self a week or so ago and behaving oddly. I am sure its knackered.

We are moving once we have found a new house to buy anyway, so not overly bothered, but wasn't expecting the kids toy to start beeping when lighting the hob.

RF interference and the radiator acting like an antenie to either induce the control circuit to trick it to beep or if the toy uses RF itself then its getting a mimic command signal.

uksparks · Sep 2, 2014

I was thinking its interference, but wasn't 100%, but you are more than likely correct.

I did put the toy on the actual cooker and see if it did it, but it didn't.

It'll only do it if you turn the ensuite hot water tap half way on

Gavin A · Sep 2, 2014

I'd suggest you stop gawping at it and get the tester out to find out why the igniter is apparently putting power into the rads in one form or another.

...you'll need a better piece of kit than a MFT to identify the frequency and magnitude of what is happening there...:stooge_curly:

tazz · Sep 3, 2014

A good 3kv plus to produce a spark.....just like the first radio transmitters, which had no defined frequency in low bands 1khz to 60mhz.....would suspect this kids till has crude rfid plastic cards to check in, working on 125khz....and your bonding is a great aerial with the water pipes...bet your daughter will charge you £25 for those pancakes....lol

Definately RFI in my opinion,a lot of things can cause it,When you work in hospitals some of them actually specify certain types of equipment that you are not allowed to use as they can play havoc with the equipment in intensive care,certain types of welder spring to mind.
