**Brand:** Dr.coffee
**Milk Frothing Issue:**
- Ensure the milk frothing jug is not completely sealed during milk frothing process to allow for proper pressure buildup.
- Store unused milk in the refrigerator and thoroughly clean the milk tube to prevent blockages that may affect milk frothing.
- Perform a deep clean of the milk system to resolve issues.
- Use full-fat milk for optimal milk frothing results; using thick milk or oat milk may lead to abnormal froth or difficulty in milk suction.
**Residual Grounds Box Reminder:**
- Empty the residual grounds box before shutting down the machine to ensure accurate detection and reset of the count.
- Manually confirm the box has been emptied when prompted on the machine screen for the count to reset.
**Water Reservoir Tray Installation Issue:**
- Avoid adjusting the water reservoir tray while the machine is in operation to prevent misalignment of the brew unit.
- If the tray cannot be installed, remove the residual grounds box, install the tray, perform a quick clean of the brewing system, and wait for the brew unit to reset before reinserting the box and tray.
**Bean Hopper Grinding Adjustment:**
- The bean hopper grinding calibration is factory-set and calibrated; avoid unnecessary adjustments.
- If minor adjustments are needed, recommend adjusting within a range of plus or minus 1 level for finer adjustments (generally below level 5) to compensate for wear and tear after prolonged use and maintain optimal taste quality.
