Boiler making strange intermittent noises (see video link with sound)

[scuava]

I have an electric boiler which has started making noises intermittently, which sound like it could be the pump into it.

See this video to illustrate the noise it makes (the sound started up at the 17 seconds mark):

It seems to do this every few minutes, occasionally very often, other times more rarely.

This doesn't seem to cause any issues and I still have hot water working as normal. But I'm worried it may be a sign of a bigger problem, and the noise is slightly annoying.

I've read up on the internet but can't seem to identify the issue exactly.

Can anyone advise what the issue might be, and how to fix it please? Or whether I need a plumber to come and check it properly.

Thanks!

That cable from the immersion heater needs sorting...it's been pulled out from cable clamp.
Looks like you might have a shower pump...show us the other pipework around the cylinder.

that is a hot water cylinder with an immersion heater with terrible wiring, it is not an electric boiler , that is something completely different, what pump are you referring to , there is no pump in your video
