Weishaupt Mechanical Vibration / Mounting Fault

Water heater vibrates excessively or rattles when the fan or burner is running.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose fan mounting screws, Unbalanced fan impeller, Loose casing panels, Unit not securely fixed to wall

Safety: Isolate power before tightening any internal components.

Check wall mounting: Ensure the Weishaupt water heater is firmly fixed to the wall and that the wall is solid enough to support it.
Tighten panels: Tighten all accessible casing screws and ensure panels are correctly seated.
Inspect fan: With power off, check that the fan is securely mounted and that the impeller is not damaged. Tighten mounting screws if loose.
Professional balancing: If vibration persists, the fan may need replacement.
