Joven as far as I know it will cut off once no more water supply.
Before we can give comment, can provide the model? Like it has internal pump or not.
My first waster heater was Joven with internal pump, used for 7 years before the motor failed. It will stay on until I off the main power.
Normal operation mode is I turn on the main water supply, it starts and if I want hot water, just set the thermostat to required. Before turning off the main water supply, I always turn off the thermostat for cold water first.

i'm using joven 880e, no water pump....

normally i just ON the outside switch and turn ON the water supply, the heater(red light indicator) will ON....

but now the heater will ON even the water supply is off. Then, i heard water boiling sound until it off by itself, should be thermal cut off which is normal feature...

i checked the user manual that 880e model got one auto flow sensor switch which it will turn off the heater when no water coming (mean water supply turn off)....that's why i suspec the flow sensor switch is not working...

try call the service centre and see how coz my warranty already expired....

Well, I don't really suggest my way as far as possible, as incident regarding to water heater every year sure has few.
You can turn off the main power or fuse out before you open the cover.

yes, I think call service centre and see, if can repairable and price below rm100, just change the sensor....

if not buy the new one....quite, just used for 2 years only

Unlikely to be rm100, but just give a call and confirm.
Or just see your nearby got people do such repair or not.

Like that, never know that unit without pump so cheap.
I may consider scrap it and buy a new 1. Since water heater needs to be changed after few years.
Just a sad case for you that you need to change it after 2 years.
