Error Description Corrective Action
E01
SUPPLY SENSOR
NOT CONNECTED
51 Supply sensor not connected. Check harness and sensor.
E02
RETURN SENSOR
NOT CONNECTED
52 Return sensor not connected. Check harness and sensor.
E04
DHW SENSOR
NOT CONNECTED
55 DHW sensor not connected.
If DHW Mode is not intended to be set to Mode 1,
DHW Store with Sensor, then change it to the
appropriate Mode.
Check harness and sensor.
E05 STACK SENSOR OPEN 57 Flue gas sensor open. Check vent temperature, harness, sensor.
E11 SUPPLY SENSOR SHORT 59 Supply sensor shorted. Check harness and sensor.
E12 RETURN SENSOR SHORT 60 Return sensor shorted. Check harness and sensor.
E13 STACK SENSOR SHORT 65 Flue gas sensor shorted. Check harness and sensor.
E14 DHW SENSOR SHORT 63 DHW sensor shorted. Check harness and sensor.
E19
COMMUNICATION ERROR
E2PROM ERROR
0
Problems reading from or writing
to e2prom.
Contact PB Heat Representative.
E20 FALSE FLAME DETECTED 35 False Flame detected. Verify no flame in observation port. Check Sensor.
E21 HOT/NEUTRAL REVERSED 44
Phase and neutral of mains
supply are reversed. Verify polarity of incoming wiring. Check boiler
ground and harness.
E22 POOR GROUND 43
No earth connected or internal
hardware error.
Check boiler ground and harness.
E23 NET FREQUENCY ERROR 45
Mains frequency differs more
than 2% from 60Hz.
Contact electrical provider and/or an electrician.
E24 POOR GROUND 46 Earth connection is not ok. Check boiler ground and harness.
E25 BLOCKED VENT 38 Blocked Vent Switch is Open
This error applies to PF-200, PF-210, PF-300 and
PF-399 models. Check for blocked vent pipe or blocked
heat exchanger. Check switch and tubing to switch.
E26
BLOCKED CONDENSATE
DRAIN
41 Condensate drain blocked.
Check condensate tanks, hoses, condensate switch,
and harness.
E30 HIGH STACK TEMPERATURE 39
Flue gas sensor above max flue
se diff.
If flue pipe is hot, check flue temperature and
compare to values shown Table 8.5. Check for
proper gas input and combustion readings, check
for dirty heat exchanger.
If flue pipe is not hot, check flue sensor and
harness.
E31 LOW WATER 36 Water level is too low.
Check boiler water level, low water cut-off, harness.
If a LWCO is not used, a jumper should be placed
between terminals #9 and #10, LWCO Contact.
E32 HIGH RETURN TEMP 40
Return temperature is above
194°F (90°C). Check for reversed supply and return piping or
pump installed backwards.
E42 INTERNAL HDWRE ERROR 47 Internal hardware error. See Note*
E45 INTERNAL HDWRE ERROR 31 Internal hardware error. See Note*
E46 INTERNAL HDWRE ERROR 32 Internal hardware error. See Note*
E47 INTERNAL HDWRE ERROR 33 Internal hardware error. See Note*
E48 INTERNAL HDWRE ERROR 34 Internal hardware error. See Note*
E51
RESET BUTTON ERROR
PLEASE WAIT.
66
Reset button pressed more than
7 times within one minute. Wait five minutes. If error does not clear, replace
control.
* If persistent blocking errors, E42 through E48, occur, systematically disconnect all wires that were not supplied by the factory with the exception
of the power supply (CH T’stat, DHW T’stat, LWCO and Pumps). If the error code goes away, determine if there may be feedback from one of
the circuits. If the Error occurs with all of these disconnected, there is likely a problem with the control board.
