Tell the team if movement or access changed after flooring work. A new surface, threshold or raised edge can affect the machine's position and the ability to remove it safely.
Understanding this situation
That timing is a clue, not proof that the appliance itself is sound. Heavy vibration may also have other causes, so the relevant facts include when the change began and whether the machine has visibly shifted.
A useful next step
Do not pack random wedges under a connected machine or climb onto it to suppress movement. Stop operation if it moves violently. Describe the floor alteration and any trapped access rather than expecting an engineer to discover those restrictions on arrival.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
