LG F1247TD5 noise - pump?
Hi There,
Our washing machine over the last few months has developed a noise - it sounds like it's the pump but before I pull it apart, are you able to help diagnose this properly from the video?
Many Thanks, Gareth

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
LG F1247TD5 noisy during wash traced to recirculation pump
- The problem
- LG F1247TD5 washing machine developed a noise over several months. The noise occurred during the wash cycle and not on spin. Water through the recirculation nozzle was only weeping after cleaning.
- Likely cause
- Confirmed fault was the recirculation pump/pump housing assembly. Early replies considered pump versus motor/drum bearings, but later discussion and the final repair point to the recirculation pump, possibly after blockage and strain from accumulated debris.
- What fixed it
- The owner first cleaned a recirculation nozzle that was found full of gunk, but this did not restore proper water flow or stop the noise. The confirmed repair was replacement of the pump/housing unit containing the pumps. The owner also stated these machines have separate drain and recirculation pumps, and chose the complete dual-pump housing assembly.
- Checks to try
- Noise stopped when the drum stopped rotating while the pump could still be heard running
- Machine identified as a direct drive model
- Recirculation nozzle inspected and found clogged with gunk
- After cleaning, water was still only weeping through the recirculation path
- Noise was reported during wash rather than spin
- Parts or tools mentioned
- Pump / housing unit
- Recirculation pump
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

It sounded like a very dry bearing on the pump but the noise stops when the drum stops rotating and it sounds like the pump is still running ok in the background? To troubleshoot this noise you would normally take off the drive belt and let the motor run separately. However, if it's one of those direct drive machines you won't be able to do that. If the noise doesn't get any louder or worse when it kicks into spin I would suspect the pump but if the noise gets a lot louder it's the motor/drum bearings.

Thanks Andy... it is indeed a direct drive machine. After a bit more digging, it looks like it could be the re-circulation nozzle being clogged up with gunk, causing the pump to make that noise. I had a go at cleaning the nozzle and it was indeed full of gunk but unfortunately water is still not getting through (it's weeping at best) so I need to get the lid off to access the hose and see if I can clean the hose.
I'll report back once I've done this...
Hello. I didn't realise it was on wash, I assumed it was on the spin cycle. Had a realised I would have said it's likely to be the circulation pump. It might need a new one. That noise sounds more like a faulty bearing than gunged up but please report back with updates.

It took me a while to get round to fixing this but I bought a new pump / housing unit, replaced this and is now quiet! Thanks for your help & advice :-)
Excellent. Many thanks for the update and glad you got it sorted.

Hi Goaten 2000, it seems my machine is now displaying the same noises and problems as yours, could you advise on what and how you managed to fix yours? Many thanks
My machine is not making any noises on spin so it's not a bearing and only during the wash cycle.
Hi Frankie
It was the recirculation pump. These machines have 2 pumps - 1 to drain and 1 to recirculate the water. You can either replace the individual pump, or there's a unit that is the part with 2 pumps already attached (I went for this option - it worked out cheaper than a pump on it's own!)
This video give you a general guide on how to access the pump, but don't bother removing the front panel with the door - it doesn't come off! (I only discovered this after removing the door seal, which turned out to be a waste of time!)

Once you've removed the kick panel and the top panel, you'll see the pump at the bottom of the machine. Be warned it's quite fiddly with tight access, but with a bit of perseverance and patience, it can be done (and is very satisfying afterwards). Whilst the machine was apart, i took the opportunity to clean the pipes that i could access from the detergent draw, recirculation pipe etc. It's amazing how much gunk was in those pipes
Hi Goaten2000
I have also identified the same problem with the recirculation pump. We had a blockage which I have unblocked and the noise reduced however the pump still makes a significant noise on start-up so I'm guessing it was damaged under the strain. The unit you replaced (housing both pumps), was it called a Drain Pump Assembly?
Thanks
Megan
