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.
