| Common Faults and Troubleshooting for Vatti Blender | |||
| Phenomenon | Cause | Repair Method | Remarks |
| Touch buttons unresponsive | Control board failure | Visually check if the spring solder joints have cracks or voids, and if the IC pins are oxidized. | Replace the control board |
| Knob switch unresponsive | Knob switch board failure | Visually check if the encoder pins have cold solder joints or oxidation. | Replace the knob switch board |
| Control board failure | Visually check if the IC pins are oxidized, cold soldered, or bridged. | Replace the control board | |
| Cannot start program | Glass lid not tightened properly | Visually check if the glass lid is aligned and tightened. | Tighten the glass lid |
| Magnetic control switch board failure | Use a multimeter to measure if the reed switch is conductive when in contact with a magnet; if conductive, it is damaged. | Replace the magnetic control board | |
| Knob switch board failure | Use a multimeter to measure if the encoder pins are open when pressed; if open, it is damaged. | Replace the knob switch board | |
| Operation possible with lid not tightened | Magnetic control board failure | Use a multimeter to measure if the reed switch is conductive; if conductive, it is damaged. | Replace the magnetic control board |
| Control board failure | Visually check if the IC pins are oxidized, cold soldered, or bridged. | Replace the control board | |
| No heating | Heating plate failure | Use a multimeter to check if the heating plate has resistance; no resistance or an open circuit indicates damage. | Return the glass cup component for repair |
| Fuse blown | Use a multimeter to check if the two fuses are open; if open, they are damaged. | Replace the fuse | |
| Control board failure | Visually check if the IC pins are oxidized, cold soldered, or bridged. | Replace the control board | |
| Power board failure | Use a tester to check if the power board heating plate terminals have normal output voltage. | Replace the power board | |
| No stirring | Motor thermal protection | Check if the motor has been running for a long time. Unplug the power cord and let the unit sit for 30 minutes. | |
| Motor damaged | Use a multimeter to measure if the motor terminals are open; if open, it is damaged; perform a power test to check if the motor runs well. | Replace the motor | |
| Control board failure | Visually check if the IC pins are oxidized, cold soldered, or bridged. | Replace the control board | |
| Power board failure | Use a tester to check if the power board motor terminals have normal output voltage. | Replace the power board | |
| No power | Overcurrent protector has tripped | Overcurrent protector button popped up. | Press the reset button to restore |
| Power cord not plugged in properly | Check if the power point is plugged in and connected. | ||
| Power board failure | Use a tester to check if the power board heating plate terminals have normal output voltage. | Replace the power board | |
| Power board and control board ribbon cable disconnected | Use a multimeter to check if the ribbon cable is open. If so, it is a ribbon cable fault. | Replace the control board | |
| Stirring makes obvious noise or shakes | Shock absorber rubber sleeve and coupling damaged | Visually check if the shock absorber rubber sleeve and coupling are damaged or cracked. | Replace the damaged parts |
| Heating ingredients cannot be cooked | Incorrect amount of ingredients and water | Refer to the manual for the appropriate quantity of ingredients. | Follow the manual requirements |
| Start button not pressed | Press the start button again. | Refer to the manual for usage instructions | |
| Power supply voltage unstable, too low | Ensure that the power supply voltage is not lower than 198V (check local power conditions). | Use a voltage regulator | |
| Control board failure | Visually check if the IC pins are oxidized, cold soldered, or bridged. | Replace the control board | |
| Ingredients overflow | Incorrect amount of ingredients and water | Refer to the manual for the appropriate quantity of ingredients. | Follow the manual requirements |
| Power supply voltage unstable, too high | Ensure that the power supply voltage is not higher than 233V (check local power conditions). | Use a voltage regulator | |
