Tutorial - How to remove an immersion element which has been stuck in with jointing compound:
Time - Approx 1/2 hour from draining.
1, drain to below level of element
2, remove all cover, thermostat, wires etc
3, make a saw cut across top with hacksaw as in the first picture, down to the gasket but be careful not to cut through the gasket or you will damage the face which the gasket seals onto. Make another saw cut at about 45 degrees to the first.
4, with a 3mm drill, drill a series of holes across the face of the element joining the saw cuts and going round the thermostat hole and element terminals.
5, use a 5mm drill to enlarge the holes so that a continuous gap is created across the face.
6, next we need to cut through the vertical sides of the element cap where the threaded section is (first picture). Work a hacksaw blade along the gaps to clear out and parts between the drill holes. Next cut into the threaded part, being careful not to cut beyond the thread or you will cut deep into the cylinder thread and risk damaging the cylinder.
7. with a pair of grips, try to pry out the 45 degree segment. Once you have cut through enough thread you should be able to remove this (second picture). Once removed, you should be able to squash the remaining sides of the element top together to free from the cylinder and unscrew.
8, With a wire brush and miniature screwdriver, clean out the threads on the cylinder and clean any jointing compound from the mating face.
