• Code: 361.371
• Description: LPH Act Fault M. Communication error between MCU and LPH Unit (M) (error in the communication IC or cable).
• Remedy: Check the timing at when this Fail occurs. Does this Fail occur right after the power is turned On? Y↓ N→If the Fail occurs when the Drum is rotating, it is very likely due to the noise caused by high voltage leak.
