Chefman Under-Extraction / Incorrect Brew Temperature or Flow

Brewed coffee is weak or watery even when using normal amounts of coffee.

Possible Causes

Water not reaching proper brewing temperature, Flow too fast due to missing or damaged restrictor, Incorrect grind size (too coarse), Too little coffee in filter

How to Fix / Troubleshooting

Safety first: Unplug before cleaning.

Steps:

Verify you are using the recommended coffee-to-water ratio (typically 1–2 tablespoons per 6 oz of water).
Use a medium grind suitable for drip coffee makers.
Descale the machine to restore proper heating performance.
Ensure the filter basket and any flow restrictor parts are installed correctly and not missing.

If coffee remains weak, the heating element may not be reaching full temperature and could require replacement.
