Immersion heater failed.

I've discovered a lack of hot water today. I haven't changed anything.
I run the upper element on Econ 7, so the water heats overnight. Lower element is switched off at all times.
I assume that either the heating element has failed or the wiring to it.
I've looked on Screwfix and they're £17, so no big problem there, assuming my largest adjustable will fit the massive nut. Either that or I'll have to buy the correct socket at the Plumb Centre.
Is it common for these to fail? This might be the original unit that would have been fitted in 1991, so 17 years old.

There is a little thermostat on them that somtimes have a little reset button, might be worth isolating and having a look.
PS a multimeter or contiuity tester can be used to test the element. stat & safety cut outDave0 -
Test everything like Dave says, with a multimeter.
If the element has failed they can be an absolute pain in the !!!! to replace-

Often it is best left to a plumber if you can't move the element.0 -
OK. Before I get too excited I'm going to take a look after midnight when the E7 is on and make sure that the mains is actually coming on.Happy chappy0

Be very careful if the immersion heater is tight, will not budge, you could end up wrecking the tank.
I would advise getting the correct spanner for the job.;)0 -
When you place back the element, get some cylinder jointing compound from the plumbers merchant too - will make your non-leaky and hassle free.
Slightly loosen the element while the cylinder is full otherwise you may bens/distort and ruin cylinder -GOOGLE it before you ask, you'll often save yourself a lot of time.

Well, I checked last night, and the LED was on. I checked the water this morning and it was very hot.
I'm going to inspect the wiring.Happy chappy0 -
