Range tribune HE no hot water??

[Tomjr98]

Ok guys so my Range Tribune He immersion heater stopped giving hot water a couple days ago (I’m a joiner with a limited knowledge in plumbing) also the hot water capacity was never that much it would do 2 showers a day. Any ideas of what’s up with it?

looking at it i would advise getting a g3 gas engineer out as it needs work on it it has issues that you can not do.
