Possible Causes

Grind too coarse, Insufficient coffee in basket, Heat too low or removed too early, Worn gasket causing pressure loss

How to Fix / Troubleshooting

Safety first: Handle the pot carefully when hot; metal parts can cause burns.

  • Adjust grind: Use a finer grind suitable for moka pots (finer than drip, coarser than espresso). Avoid very coarse grinds.
  • Fill basket properly: Fill the filter basket level to the rim without tamping. Ensure even distribution.
  • Use appropriate heat: Use medium heat and keep the pot on the burner until the upper chamber is about 80–90% full, then remove from heat.
  • Check gasket: If you see steam escaping from the seam, replace the gasket to restore pressure.

Consistent weak coffee after these adjustments may indicate a deformed filter basket or worn internal components that should be replaced.
