Hi there,

I have a Panasonic water heater, which been using 10 years.. no complains.. It is just that now when press the stop button on it, it cannot stop the water completely anymore.. I have to tighten up the water flow for the unit to stop the water completely. After that, I can loosen the water flow and is okay.

So the question is... Is it a normal thing? Should some maintenance be done? like changing some rubber? Or just buy a new one and ask installer to replace it?

Anyway, Panasonic quality is pretty good. I have 5x units same model and only one unit has this issue after 10 years.

Any opinion? Buy new one easier?

The tombol bukak tutup air is loose maybe, that can be fixed by replacing the rubber inside

The button issue. Push and release a few times sometimes can work. Push and quickly release, let the spring force the button back.

The main problem is the rubber stopper inside out of shape. I couldn't find spare part so change the whole thing. 8 years old that time.

pasang inline valve at heater output

i am using the same model but i am using a water tap instead of pressing the big button.. do you have tap control valved?or you can buy a valve and install it before filter.. that could be a cheaper option rather than to change a working unit..

everyone I know who has this said same thing

rubber part has worn off. replace.

sounds like weak washer or spring. you turn off mains reduce pressure then the rubber seal properly.

SAME PROBLEM O ME ALSO

this.
Always rely on valve before the heater.

Already 10 years, may not be safe for your life.

10 years good la.
most water heater dont have this push on-off water flow, so only can depend on other stop-cock.

try disamble those water heater and seek for those rubber and ask panasonic if they got spare part (pretty much sure the same part were used by multiple model)

You are supposed to have a stopcock before the heater so that in the event of an emergency you can stop that.

Sometimes your water pressure too high, the internal spring cannot stop it is normal.

install at water input better to prevent internal leaking. it a 10 year old water heater.

TS, if financial allow, change a new one. sudah untung pakai 10 years.

well true, input side better

Just replace a new one. Quite easy to diy it also.

I kena once. Also panasonic. When the problem start, can still use the water flow to stop it. But later, have tu close the tap completely otherwise it will still flow out. Under warranty, i send to repair. Technician said its the stopper spoilt. 2 week to repair wor.

thanks for the sharing all your experiences. Its been 10 years, thus I believe no more warranty. And also because 10 years already, I think no more spare parts.. not sure even bother to ask Panasonic...

like one of the members here suggesting, 10 years already... better get new one even it is fully functioning? On the other hand, I do have the inlet control, so no issue to stop the water and no immediate issues to me.

If can buy same model, easy to replace la because pipe all same place. But 10 years already, impossible to same model... newer model sure need to hack a bit here and there.. It mean need to contact some contractor to help me la.. and now during MCO, I really hesitate to let anyone come to my house....

try this first. u know the small intake water filter below it. clean it.

tersumbat make water flow low pressure. if ur stopper edy used to high pressure, sudden low pressure will make the washer “loose”
