If a customer is complaining about a poor taste with their coffee, follow the steps below to troubleshoot the device. 

Troubleshooting Poor Coffee Taste

Clean the Machine

• Run a cleaning cycle or use a descaling solution.
• Clean the brew head, water reservoir, and any milk frothing parts.

Check Water Quality

• Use filtered or bottled water if your tap water tastes off.
• Avoid distilled water—it lacks minerals that help extract flavor.

Inspect Coffee Beans or Grounds

• Make sure beans are fresh (not oily or stale).
• Store them in an airtight container away from light and heat.
• If using pre-ground coffee, check the grind size—too fine or too coarse can ruin taste.

Adjust Brew Settings

• Try tweaking temperature, brew time, or strength settings.
• Some machines let you control these via app or manual buttons.

Check for Old Filters

• Replace water filters if they’re past their recommended lifespan.
• Clean or replace reusable coffee filters.

Test Different Beans

• Try a different roast or brand to rule out bean quality issues.
• Lighter roasts tend to be more acidic, darker ones more bitter.

Look for Residue or Mold

• Inspect inside the machine for any buildup or mold.
• Clean drip trays and internal tubing if accessible.
