Well, it's a bit of a guess without checking further, but you will probably find the immersion has corroded inside the tank which is causing the trip to activate.
Assuming this is the case, it needs replacing. They can be tricky things to remove, as they need a special box spanner and a careful hand so as not to damage the thin copper tank. You need to be familiar with 230 volt electrics too.
A plummer would be your best course of action.
