Some noise from the dishwasher is normal in normal cases.
For example, there is a possibility that food scraps are going down or the sound of valves to release water.
Noise may occur when the timer is operated, or when the motor is stopped for dryness, or if the dishwasher falls off the pedestal inside the device, it may sound.
Always make sure that the dishes are properly placed. If you suspect another problem, contact the manufacturer’s A/S center.
