What the symptom may mean
The unit starts without fixture use may involve water entering, sensing or discharge return. An engineer assesses the actual appliance; a symptom alone does not identify a component.
Useful details from ordinary use
Record how often it runs and which fixtures are connected. Separate the selected programme or control setting from the result you saw or heard. Keep the exact display message if one appeared.
Find the product, safely
Record the exact model from an accessible label or existing paperwork. Do not open a waste-connected unit.
Mention the fixtures connected to the unit and whether any are backing up. Stop using fixtures if discharge is not clearing.
Stop if it becomes unsafe
Do not remove covers, reach into moving parts or continue using an appliance with smoke, sparking, a burning smell, water near electrical parts or repeated tripping. Do not restart it to reproduce the problem.
