Excessive vibration; machine "walks" on the counter during brewing.

Safety first: Unplug before moving the machine.

Steps:

• Level surface: Place the coffee maker on a flat, stable, non-slippery surface.
• Check rubber feet: Inspect the bottom feet; replace if missing or hardened.
• Inspect pump mounts (advanced): Open the housing and check that the pump is secured in its rubber mounts. Replace mounts if cracked or loose.
