Hi All
what connection, if any, is there likely to be a connection between the
following two events:

- Immersion heater seems to have failed (power going to terminals OK)
- a small leak around the top of the tank, where the heater is fitted
?

Of course my next step is to try and unscrew the heater with a view to
replacing; I'm just wondering what failure mode might account for both
symptoms.

Cheers
