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”

10 years... u already have the answer.

risk of being electrocuted is high.

Not sure what can open for cleaning.. later I try to open here and there la.. everything seems very tight...

FYI, my hometown Panasonic never spoilt with more than 20+ years.. But still I replaced hometown one as more than 20 years scare scare...

it look something like this. inside like plastic filter. u not knowing mean it not been clean since 10 years too



just make sure stop the water source first

It doesnt have to be the same model. Most stand alone water like this have roughly the same concept.

Yeah, the hassle is to drill hole through the tile.

10 year, mean it's time already. Hehe. I also have change mine to newer panasonic unit. Yes, i also have the same concern for the screw hole, pipe etc. So i did few checks before purchase new one. Especially on the wall unit diameter. Than i do replace it myself. Surprisingly 3 out of 4 skrew hole is fit correctly. So i dont have to do any drilling. Just to be extra carefull when u detach/attach the power cable.

I also worry about power line as well. If not careful or mistake, can teleport into another world immediately. Thus most likely ask contractor... maybe kaotim or what...

Chances that they have some spare parts for your model are low, but still - I believe it's OK to ask them at least. A nice support can help you if there are compatible models as zerorating already said. Have you contacted them yet?
Unfortunately, my experience with water heaters was not great (and I wasn't so lucky) so I had to replace mine Rheem completely after six years of usage.

10 years already buy new lah. Wanna die electric shock?

10 years for a push mechanism to finally got problem is a miracle. Please buy 1 whole roasted babi and give back to god

Ok.. Will check with them.. Let me check the model number....

But even if I can buy the spare part.. I wonder how to replace... hahaha...

Hi guys. May I know if the water is turn off from the tap but on off switch is not press the heater of turn off or still will remain on?

open up the plastic cover and see which part to replace...it's not that rocket science inside.

My on off switch is not working. The technician came and spray some grease then ok. But I tell him if water is off the heater doesn't turn off he says it's normal. Mine still under warranty. By right no water flow heater should be turn off regarding got use the switch or not?

I think u better clarify with the technician. If no water flow but heater is still on and heating, your heating element will overheat the stagnant water and scald u when u turn on the water next (or overheat the air, which is worst and cause dry burn and plastic tank to melt). This is not normal.

But if what u meant by heater doesn't turn off is not referring to the heating element or pump, BUT the ELCB / RCD indicator, ELCB / RCD will always be on as long as the switch outside your bathroom is still on.

Remain on but there is a sensor to prevent heating of the water.
But the heater light will be 'on'.

Heater won't function till water flow.

If the on/off switch still gives problems, then call Panasonic and login a complaint.
They will send technician to change the parts free of charge since you said under warranty.
Just ensure you have proof of warranty.

When I first bought the light will be off when no water flowing.

Problem is the stupid technician says it's normal. Then I request another technician same guy come again and same he's the only one. Keep arguing with me.

Confirm the circuit board got issue. Because when I push the on/off switch to on. The temperature control knob when turn fully counter clockwise to the off position the power is still on. Now then he says no spare parts and need to refer to HQ. Very bad attitude guy. Keep grumbling and arguing with me.

PANASONIC heaters are like that one.
Do not bother to change any parts. Expensive.
Either:
1. Install an additional external valve on the inlet pipe.
2. Replace with new water heater, 10 years already paid back.

my downstair panasonic heater oso same problem after 1yr

nvr bothered to find out y cos jes off at my own wall angle valve oni

if change new 1 get those with RCCB, not ELCB

I'm replying to 4 yo thread. Thank God I managed to rectify the problem of water can't stop flowing. I suspected something wrong with the inlet body. Maybe the rubber washer need to be replaced or something.

The culprit was few grain of sands that got stuck in the inlet body prevented the valve from fully close.

my unit just started to have the problem these few weeks, is it easy to replace?
