i'm using joven water heater which usually i just off the main water pipe and the heater (red light indicator) will off, just the green light ON.

now the heater did not turn off after i off my water pipe and i heard boiling sound from the water heater until it cut off by thermostat and heater off itself....

i suspect the auto flow sensor switch not working and cannot detect no more water coming.....

can i still using the water heater as it just flow sensor switch not working only? now i switch off the heater after i off my water pipe....i just used for 2 years but only twice a week....

Better don't use and call the service center for help.

You don't want end up like last yrs the jap couple in mont kiara.

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....

I may contact a wireman that I know which can do the repair work. Anyway, just wait for the SC reply to you then see how it goes.

you mean you got wireman contact to repair the water heater? i think is the flow sensor switch not working, not sure where is located....other than that, it working fine...

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.

i just brought it for rm250...i think now also selling around this price...

if more than rm100, better buy new one....yup, next week call and see...

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.

just repaired the heater....not a big problem, just the sensor stuck in the inlet, cannot go down cause the heater cannot auto off...

change it plus workmanship rm60....better than change a new one, use few more year first...

Hi, do u mind share your contact for the repair?

Just call joven, they will send ppl to check
