(Little noise may be generated during the high-speed SPIN.)
The current breaker may be down due to the lack of the current when the
wash machine and other apparatus are used.
In this case, execute the cold water wash to check whether the current
capacity is lack.
If above points are not found, the PCB assembly is out of order. Replace it.
