Bakit lagi sumasabog fuse ng washing machine?

[fourtheboys96]

Yung automatic washing machine namin sumabog dahil sa power surge (see related thread on my laptop huhuhuhu). Nung mangyari yun, nakasaksak siya pero ndi naka-on.

Nung una ko pinalitan yung fuse, nag-on siya tapos sumabog yung fuse nung pag off ko. Tapos pinalitan ko uli ng fuse, ngayon naman, sumabog agad pag saksak ko pa lang ng plug. Tapos pinalitan ko uli, parehas ng nangyari nung first time.

Dun sa diagram sa likod ng washing machine ang nakasulat ay Fuse 230V~5A. so 5 amps yung fuse na binili ko.

Same situation pala dun sa DVD player namin. Nung unang pinalitan ko yung fuse ok siya, then ngayon no power uli.

Ano ba dapat ko gawin? Mukang tama naman yung replacement fuse na nabili ko. Yung isang TV namin na pinalitan ko ng fuse ay OK naman.

You might have a problem with the power in your area if you are having similar problems with other electrical appliances aside from the washing machine.

[badkuk]

i'm no expert, but could it perhaps be the electricals of the washing machine itself? maybe something shorted out, or some component got busted?

[leinahtan]

Washing machine panels is susceptible to water ingress if not used properly. Water may have sipped through the panels thus causing electric circuits to be shorted. Try opening the wm panels and blow dry the components.

Using Voltmeter, measure/ monitor commercial power in the outlet..check and compare with the appliance specifications if operating voltage is within range. Ususally motorized appliances and some appliances using stepdown transformers have limited voltage tolerance as compared to appliances with switching-type power supplies w/c have wider tolerances (around 100~240VAC). Over/ undervoltage and incorrect frequency can produce current surge..

Ask your neigbors if they encounter same problem..

Report to Meralco if your getting below 190V and beyond 240V..

Power surges usually happens during thunderstorms, heavy winds..Better protect using line-interactive UPS.

Your washing machine could have build-up bad insulation over time because of exposure to power irregularities. Clean motor, check starting capacitor for leakage..Modern washing machines have complex power supplies for the controller..Better bring to electrician for checkup..

try to check the voltage output on those outlets where the washing machine and DVD player used to be plugged. if it's within 230V might be the fuse wasn't able to cut the surged and forced it's way to the unit/s. in short, shorted na nga.

Besides what others have already posted ...

Check what kind of fuse you're replacing.

You may have used the same Amp rating ... but if you use a Fast Blow fuse on an equipment which needs a Slow Blow, chances are you'll pop the fuse everytime you turn it on.

If your not and expert with electrical don't mess with it.

It always states in the manual.

Bring to the nearest service center. or call a qualified technician.

most electronic appliances have varistors for surge protection ... they do their job well

but strong surges can damage them, causing them to short out and blow the fuse ... in many cases, removing the varistor from the circuit (and replacing the fuse) would restore normal operation (temporarily without surge protection until varistor is also replaced)

if the other appliances in your house don't have the same problem, baka shorted nga yang washing machine mo, bro. . .be thankful for the fuse is doing what it's supposed to do, which is to protect your equipment. . .pa-check mo sa qualified technician

[bambino]

ipatingin mo na lang sa house electrician para sigurado

[fourtheboys96]

linawin ko lang. nangyari lang yung power surge once. parang nag brownout then bumalik ulit kuryente in less than a second. walang time para maghugot ng saksak ng appliances. at sa balita ko, madami naapektuhan. ndi kami meralco sa nakakonek. diretso mula NPC kuryente tapos ang campus na ang nagmamanage ng distribution. ang cause daw nung power surge ay dahil may 2 wire na ibang institution ang sibusplayan ang nagdikit after mabaksakan ng puno.

nway, balik sa washing machine.

- sigurado ako ndi dahil leaking water ang sanhi ng problema.

- ok na ngayon ang voltage sa bahay at normal ang operation ng appliances.

- baka nga mali ang fuse na nabili ko. same amp rating pero ibang type yung nabili ko. kasi pagsaksak ko pa lang ng plug eh sumasabog na agad yung fuse. isang beses nag-on yung washing machine then pag turn off ko, tsaka naman sumabog ang fuse.

- posible ba na mag-short yung appliance kahit na ndi siya naka-on? kasi nung nangyari yun, nakasaksak yung washing machine, pero ndi siya naka-on. yung isang TV namin ganun din pero after palitan yung fuse, gumana na siya. unfortunately yung mas malaking TV eh naka-on at nanonood kami nung mangyari ang surge.

balak ko inspect muna wiring then pag ndi pa din makuha, tsaka ko dadalhin sa technician. haayyyy. . . .

[wildthing]

masyadong eratic power sa inyo or there's another short circuit in the washing machine. try to have your line's checked and may be an installation of a circuit breaker for your washing machine is another possible option.

pagkakasi malakas ang higop ng current at hindi kaya ng linya, nagiinit ito and if fused ito, pedeng yun fuse ang bibigay agad.

hth

[fourtheboys96]

after the power surge, the problem now is with the washing machine itself. not with the wiring of the house. the rest of the appliances are now working fine so that confirms that there is no problem with house wiring.

now, what I am trying to figure out is how to isolate the problem in the machine itself. from what i've read in the net, there is probably a short circuit in the wiring of the washing machine. i'll try to check later tonight. good thing i bought a multi tester a couple of months ago. will use it for the first time.

[badsekktor]

baka nasira yun step down transformer nung washing machine.... pacheck mo na lang sa service center

[CVT]

Don't get a fuse with a higher current rating. Use the prescribed fuse spec only (5A, as you stated earlier). There is something wrong with your washing machine that is causing the fuse to blow. It could be the motor. Have a qualified technician check it out.

mukhang dalhin ko na lang sa technician. may grounded part sa washing machine. tinest ko yung motor for resistance, meron. eh accdg sa nabasa ko dapat wala pag naka-off. tama ba?

[jatcos]

tama bro, sa tech nalang..nabanggit mona electronic control yan, malamang doon naggaling ang problema..kung manual timer lang madali troubleshoot, pwede mopa i-bypass yung speed selector

saan mo sinukatan, sa plug ba? sa electronic control meron loop masusukat kung transformer type ang power supply ng electronics, pero capacitance ang masusukat kung switching type ang ps. Sa manual control, loop ng stator ang masusukat mo (almost full short) kung nka turn on ang dial/timer to on..da best kung mabubuksan mo at malinisan mga contacts including motor..dirty surface induce unwanted current..check also starting capacitor bka may leak o lobo na.
