What the symptom can mean
Product delivery depends on the compartment, programme and water flow. A full conditioner slot and dry powder left behind need different consideration rather than a universal drawer replacement.
Name the product and compartment
Keep the detergent or conditioner name, amount and drawer position in your notes. Say whether the residue is dry powder, diluted liquid or a full conditioner compartment. Mention a recent drawer refit or product change.
Describe the wash result separately
Clothing residue and a liquid-filled drawer are related observations rather than proof of one failed part. Include the programme and whether filling or rinsing sounded different from the usual sequence.
