Coffee maker makes loud banging or rattling noises during brewing.

Possible Causes

Air in water circuit, Loose pump mounting, Kinked inlet hose, Scale causing irregular pump load

Safety first: Unplug before opening the housing.

Steps:

Bleed air: Run several water-only cycles to purge air from the system. Ensure the tank is full.
Check placement: Make sure the machine is on a stable, level surface and not touching other objects that can amplify vibration.
Descale: Scale can cause the pump to work harder and noisier. Run a descaling cycle.
Inspect pump mounts (advanced): Open the housing and verify that the pump's rubber mounts are intact and that the pump is not touching the plastic housing directly.
