Remove loose stored items carefully without pulling or bending the hose, and keep the disposer unused while visible damage is assessed. A crushed hose or strained connection is more than a housekeeping issue if water can escape.
What the observation tells you
Notice which appliance the hose serves rather than assuming every flexible tube carries disposer waste. Do not disconnect it to look for debris or leave it stretched in a new position. Photograph any lasting kink or wet connection.
A useful next step
If its shape or connection remains doubtful after the storage is cleared, request assessment. Explain any drainage change that coincided with filling the cabinet.
