Inherited a “nice” LG front-loader… turns out it’s mold city. How do I clean the unreachable parts?

Just bought a house with an LG front-loading washer (grey). Looked great until I opened the gasket and detergent drawer… both were full of mold.

I scrubbed the gasket and drawer with a cleaning solution (Amazon stuff), and over a week got ~80% of the visible mold off. I also ran the washer’s Tub Clean and used Affresh three separate times.

Every time I run another clean cycle, black specks/chunks still show up in the drum, like the internal hoses/dispenser path/recirculation lines still have mold or biofilm I can’t reach.

What I’ve tried Pulled back the door gasket and scrubbed thoroughly Removed and washed the detergent drawer + housing area Multiple Tub Clean cycles with Affresh x 3 times

What’s the best way to deep-clean the internal paths on these LG front-loaders (dispenser channel, recirculation, drain lines)?

Any enzyme/biofilm cleaners that actually work vs. just perfuming it?

At what point is this a lost cause vs. worth disassembling/replacing hoses/gasket?

I hate the idea of tossing a working machine that still has life left, but I’m stuck. Any proven steps or product recs would be awesome.

TL;DR: Cleaned visible mold, but clean cycles still release mold chunks. Need advice on deep-cleaning the internal plumbing or knowing when to give up.
