Measures when safety device is on
Failures Failure Codes Symptoms and Causes
Hot Water Temperature Sensor
Failure
E0
Disconnection or short circuit of hot water temperature
sensor
Ignition failure E1 Initial ignition failure
Poor detection during ignition E2 Re-ignition failure during combustion
Primary overheat protector failure E3
Overheat protector for heating failure or its component
failure
Hot water boiling safety device E4 Hot water temperature increase over the limit

chamber before or after activation
Poor communication EC Communication failure between main circuit boards
EEPROM failure EE Poor memory IC
Wind pressure switch (counter-
pressure safety device activated)
EH
