We use it regularly, probably 2-3 times a week... And we constantly leave the drum door open after a wash and we don't let wet clothes sit inside for ages. However we seem to constantly see mould build up in the tray...

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Mould recurring in LG washing machine dispenser drawer

The problem
The user reported repeated mould build-up in the detergent tray despite regular use, leaving the drum door open after washing, and not leaving wet clothes sitting in the machine.
Likely cause
The accepted reply said the most likely cause is damp and detergent or fabric-conditioner residue collecting in the dispenser drawer and housing, where airflow is poorer than in the drum. It also suggested possible contribution from overuse of detergent/conditioner, partially blocked spray holes, or water sitting in the drawer after a cycle.
What fixed it
Recommended action was to remove and thoroughly clean the dispenser drawer and the drawer housing with hot water and a small brush, clean reachable water jets above the drawer, reduce excess detergent or conditioner if applicable, leave the drawer slightly open after use as well as the door, and run an occasional hot maintenance wash or machine cleaner cycle. If excessive standing water remains or anything beyond normal cleaning is needed, further diagnosis should be carried out by a suitably qualified appliance engineer.
Checks to try
  • Cleaned or inspected the dispenser drawer and drawer housing
  • Checked detergent and fabric-conditioner quantity/residue
  • Checked the spray holes/water jets above the drawer for blockage
  • Checked whether standing water remained in the drawer after a cycle
  • Left the dispenser drawer slightly open after use
  • Ran a hot maintenance wash or machine cleaner cycle
Parts or tools mentioned
  • Hot water
  • Small brush
  • Old toothbrush
  • Machine cleaner

Safety: Isolate the appliance from the mains before inspecting anything beyond normal user cleaning. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Mould in the dispenser drawer is very common, even when you do the “right” things with the door and drum. The drawer area stays damp, catches detergent residue, and gets less airflow than the drum.

1. Pull the dispenser drawer right out and clean it thoroughly. Most LG drawers unclip or have a release tab. Wash the drawer and the drawer housing with hot water and a small brush or old toothbrush, especially around the softener section where slime often builds up.

2. Check what you are putting in. Too much detergent or fabric conditioner often leaves residue which feeds mould. Try using a little less, and dilute fabric conditioner if it is very thick. If you use powder, make sure it is fully flushing through.

3. Clean the water jets above the drawer. If the spray holes feeding the drawer are partially blocked, detergent can sit there instead of rinsing away properly. Wipe and brush what you can reach.

4. Leave the drawer slightly open after use as well as the main door. Many people leave the drum door open but shut the drawer, which traps moisture in exactly the place mould grows.

5. Run a hot maintenance wash. An occasional hot wash, or a machine cleaner on an empty cycle, helps remove detergent slime inside the dispenser system and tub.

6. Check for standing water in the drawer after a cycle. A little can be normal, but if it is excessive there may be a partial blockage or water flow issue.

If you inspect anything beyond normal user-cleaning, isolate the appliance from the mains first. For internal electrical work, ask a qualified appliance engineer. If you want, I can also suggest the best way to clean the LG drawer housing itself, as that awkward area is often the real source.

    By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.

  • Watch for sharp edges

    Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.

  • Water appliances can leak

    Turn off the water supply before disconnecting any hoses.
