How to clean and service a washing machine soap drawer & fabric conditioner tray

If you don’t clean this then you will get a congealed mass of conditioner or soap detergent building up which can lead to unpleasant smells and mould in the washing machine. It can also cause other issues, like the soap drawer not clearing the water properly or may cause the machine to leak from the soap drawer in extreme cases, as well as resulting in the machine not taking the conditioner into the drum on the final rinse.
