Why is there water on the floor in the bathroom during an appliance cycle?

Use location and timing to separate supply, drain and condensate connections around showers, drains, seals, extract ventilation and wet-room layers.

What the timing tells you

The phrase during an appliance cycle is diagnostic context. Compare the symptom before, during and after that trigger.

What is special about this location

Showers, drains, seals, extract ventilation and wet-room layers create pathways that are not visible from the finished room.

Start with competing explanations

Compare supply, drain and condensate connections. Do not select a cause from appearance alone.

First useful check

Use the linked check to create a timeline or pattern, then follow the strongest cause family to its full dossier.

Repair decision

Avoid cosmetic work until the source or mechanism is controlled and the original trigger no longer reproduces the symptom.
