Oil filled radiator - not working (West Finchley station N3)

Looking to give away a faulty oil filled radiator max 2500W model number BOH2503D.

I've taken it out of family storage last winter, to heat up my shed, and noticed that it doesn't heat up. The display turns on and is working, can change the settings and what not, but for some reason I can't get it to actually heat up.

I've spoke with family members and they don't remember what happened to it. Can't see any damage on the outside, so maybe it just needs a new heating coil? Still heavy, and doesn't seem to have leaked oil where it was stored. I have bought a small cheap fan heater instead, and unfortunately don't have the time to fix it.

I've taken measurements of it and it's on one of the photos.

If no one is interested, it will be taken to the recycling centre on Saturday.

Thanks
