Code
Name
Possible causes
Heater response
Possible solutions
F23
No heat
- element failure
- ECO tripped/malfunctioning
- triac(s) failed open
- relay/contactor malfunctioning
- control board failure
- inlet water supply out of spec
Heating will be disabled after
30 seconds of continuous no
heat condition.
- measure element
resistance with the unit
completely turned off
F24
Low heat
- undervoltage
- triac(s) failed open
- control board failure
- inlet/outlet thermistor(s) failure
Heating enabled, reduced
performance (lower outlet
temperature).
- verify power supply
(voltage) while heater is
running
F33
Residual heat
- internal water temperature elevated
without flow
- both triacs failed closed
Heating disabled until outlet
temperature falls below the
reactivation temperature
(see default parameters
table).
- run water through the unit
F34
Overvoltage
- inlet voltage is too high compared to
the stated heater specifications
Heating enabled, reduced
performance (higher outlet
temperature).
- have certified personnel
verify the inlet voltage
- provide voltage within
specified range
F36
Undervoltage
- inlet voltage is too low compared to
the stated heater specifications
Heating enabled, reduced
performance (lower outlet
temperature).
- have certified personnel
verify the inlet voltage
- provide voltage within
specified range
F38
High flow
- flow is too high to heat the water to
setpoint temperature
Heating enabled, unit
operates as intended (lower
outlet temperature
possible).
- reduce flow (outlet flow
restrictor, faucet aerator)
F47
Inlet thermistor
failure
- inlet thermistor interrupted or
disconnected
Heating enabled based on
default inlet temperature
setting (see default
parameters table;
higher/lower outlet
temperature possible).
- inspect connections/wiring
of inlet thermistor
F48
Outlet
thermistor
failure
- outlet thermistor interrupted or
disconnected
Heating enabled, auto
calibration disabled.
- inspect connections/wiring
of outlet thermistor
F64
Freeze warning
- inlet temperature is too low (below
35°F)
Heating disabled while
condition is present.
- increase inlet water
temperature above 35°F
