Error generation
The error is generated when the data from the EEPROM is not received correctly.
EEPROM (Electrically Erasable Programmable Read Only Memory): A memory chip that holds its
content without power. It can be erased, either within the computer or externally and usually requires
more voltage for erasure than the 5 volts used in logic circuits. It functions like non-volatile
RAM, but writing to EEPROM is slower than writing to RAM.
Supposed causes
The possible cause is a malfunctioning hydro-box PCB.
Troubleshooting
Caution

occurred.
Switch the power off
and on again to restart.
The malfunction may be caused by an external
factor, rather than damaged parts.
Locate the cause and correct the situation.
