It might prove a little difficult to undo and unscrew the faulty
immersion element. How old is it? Any sign of additional sealant or
corrosion? They can be very stiff to undo.

If you try loosening it - try first to see if it will move with a full
tank of water so it has some weight to counterbalance the spanner force.
The danger of that is that it might leak afterwards!

Last one I did came undone but distorted the tank slightly.

Unless she cant do without the immersion heater it might be best left
until this virus bollyarks is over and done with -- just in case it wont
undo and (worst possible case) need a replacement tank ?????



I had to resort to the method shown in this video

As there is a small amount of plastic in the fitting - temporarily
disable any nearby smoke alarm.

The quality of the spanner can also make a big difference. Those made
from a stamped out flat piece of steel can easily distort before the
fitting moves.
