LG WASHER CUTS OUT
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
Solution Summary
AI-generated from this discussion
This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
LG F1443kds powers off after a few minutes with PF error
- The problem
- LG washing machine F1443kds was repeatedly cutting out with PF (power failure). It first happened at different points in the wash, then progressed to switching off after about 5 minutes even when only powered on. The display, sounds and programme selection were otherwise reported as normal, and it did not blow a fuse or trip the breaker.
- Likely cause
- A mains-related internal electrical fault was suggested. The strongest supported possibilities discussed were a failing main PCB, or a fault on the mains suppressor/capacitor. An external supply fault was considered less likely because multiple wall sockets were tried with the same result. The exact failed part was not confirmed.
- What fixed it
- No repair was confirmed in the discussion. Advice was not to fit a PCB speculatively because the fault was not guaranteed to be there, and because a poor connection could overheat. Further diagnosis should be carried out by a suitably qualified appliance engineer.
- Checks to try
- Tried the machine on about four different wall sockets with the same fault
- Observed that it powered off after around 4 minutes, then after cooling/restarting lasted just over 2 minutes
- Noted it seemed to stay on longer when cold
- Confirmed it did not blow a fuse or trip a breaker
- Smart diagnosis/app only reported PF power failure
- Parts or tools mentioned
- main PCB
- mains suppressor
- capacitor
Safety: A poor connection was mentioned as a possible risk for burning out or catching fire if left plugged in, so professional diagnosis was advised.

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

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.
