Cover of the heater

The cover for the immersion heater of my Pulsacoil has come off. It's cracked and is revealing some live wires underneath. There seems to be a rusty peg at the bottom where the earth wire is connected. I'm wondering if the whole element is starting to corrode.

Does the whole thing need to be replaced?

thanks

Hi uakram,

Yes corrosion of the cap fixing stud tells us the heater element is leaking. The 'rusty peg' is all that's left of a stud that started off 50mm long! A common problem on Pulsacoils of all types. For yours to have corroded to the point where the cap fallen off indicates it's been leaking a Very Long Time...

The whole heater element needs replacing, but not the whole appliance. Best to replace both heater elements while it is drained down.

Cheers, Mike
