LG WASHER CUTS OUT

[Thermoman]

Hi

I have a LG washing machine  F1443kds which keeps cutting out on power

its error code is PF  (power failure)

it takes a few mins after switching off before it comes back on

but it doesn't blow a fuse or trip a breaker

its a direct drive with smart diagnosis  I let it talk to the phone via the app but just says power failure

 It started cutting out during different points of the wash cycle

now I have narrowed it down to the fact it is just cutting out after about 5 mins even if I just turn on the power 

all the graphics and sounds work fine all the programs work fine 

I am now thinking the pcb  ? But not sure

thanks for any help

Have you tried it in a different wall socket first just in case?

[Thermoman]

Yes I have tried about four different sockets but still the same

thanks

An update

I switched the power on to the Washing machine it took 4 minutes to power off

then after about a minute I can switch it on again

timed it again and it was just over 2 mins

so it seem that if the machine is cold it stays on longer

does it sound like a faulty component on the pcb?

thanks

It could be a fault in the pcb but not guaranteed so it would be too risky to try fitting one. If it's a poor connection somewhere you risk it burning out or even catching fire if left plugged in. I would get an engineer in.

look like that's what's got to happen

the washer is like new and it has a good capacity 11kg

have you heard of this problem before?

Thanks

It's not too common but you can get main pcb failing.Another possibility could be a fault on the mains suppressor or capacitor but again it's not something I would advise looking at. Let us know if you get an engineer out what it is.

Will do
