Damp smelling washing machine

[timeforachange999]

Sorry I know this has probably been asked before but I can't find a thread. My washing machine drum smells damp. I've done a 90 degree wash twice but the smell persists. Does anyone have any suggestions for how to fix it?

You may already have done all of these...but I'd say:

Empty the filter (usually down the bottom somewhere, put down towels first and a baking tray to catch the water as there is always SO much more than you think)

Add soda crystals to your 90c service wash, or get one of those dr beckman sachets from the supermarket

Wipe the door seal inside and out

Take out the drawer and wash it, and wipe out the whole inside of the drawer space (including the roof)

Leave the door and drawer open after every wash to let the inside air dry
