Lg Fuzzy Logic Wf-T502Th Top Loader

Hi

Those brown flakes are often a mix of detergent residue, fabric conditioner, grease and limescale, so you’re on the right lines looking at the inner tub. On many LG top loaders of that era, the tub fixing bolt is usually a large metric size, but I wouldn’t want to guess the exact socket and send you down the wrong path.

1. Isolate the washer from the mains first before stripping anything down.

2. Check the bolt head properly before buying tools. On LG top loaders it is commonly around 36mm to 38mm for the tub nut/bolt, but some versions differ. A vernier, ruler, or even measuring across the flats with a tape will quickly confirm it.

3. Before removing the tub, also check under the wash plate/pulsator and around the top tub ring. A lot of scrud builds there and can be cleaned without a full tub removal.

4. If the bolt is seized, don’t force it blindly. Use penetrating oil and make sure you know whether that model uses a normal or reverse thread. Forcing the wrong way can cause a lot of grief.

5. Once apart, clean the outer tub, inner tub holes, pulsator underside and any hidden crevices manually. Chemical cleaners alone often won’t shift established scrud.

6. If the flakes return quickly afterwards, check detergent use. Too much liquid detergent or conditioner is a very common cause.

If you want, I can help you work out the likely size from a photo of the bolt head. For any internal electrical work, or if you’re unsure about dismantling, it’s safest to use a qualified engineer.
