Error information
oPE-30 M30 Detection of AF error But E63 is not displayed
oPE-32 M32 Detection of drying up water It is always displayed at test run
oPE-33 M33 Detection of disconnection of cylinder water temp sensor
oPE-34 M34 Detection of suspension of water supply
oPE-35 M35 Detection of water pump error
oPE-40 M40
An error has occurred to either unit at master
and slave operation.
Normal units are in automatic backup
operation.
Please service the unit which an error has
occurred according to error code.
· Message of [disconnection of cylinder
temperature sensor]
Hot water temperature sensor on
the cylinder (Tht-1 to Tht-9) may be
disconnected.
· Check the connection and the
characteristics of all hot water temperature
sensors on the cylinder and if there is a
problem, connect it securely or replace it.
· If no problem on sensors, replace control
PCB.
