What does FLOW_SW_NOT_CLOSED mean on PEERLESS PureFire PF-210?
If your PEERLESS Boiler displays 'FLOW_SW_NOT_CLOSED': 1. Check for electrical continuity between wires connected to terminals 9 & 10 from the field supplied flow switch. 2. If there is no continuity, check to be sure the circulator is working. 3. If the circulator is working correctly, check the flow switch.
How do I fix a blocked condensate drain on my PEERLESS Boiler?
If your PEERLESS Boiler shows a 'BLOCKED CONDENSATE DRAIN' error, check the condensate tanks, hoses, condensate switch, and harness.
What to check if my PEERLESS PureFire PF-210 shows a low water error?
Check the boiler water level, low water cut-off, and harness. If a LWCO is not used, a jumper should be placed between terminals #9 and #10, LWCO Contact.
What to do if there is a false flame detected before ignition in my PEERLESS PureFire PF-210?
If you're experiencing a false flame detected before ignition with your PEERLESS Boiler, check the flame sensor and igniter to ensure there are no shorts to ground.
How to fix hot/neutral reversed error on PEERLESS Boiler?
If your PEERLESS Boiler displays the error 'HOT/NEUTRAL REVERSED', verify the polarity of the incoming wiring and check the boiler ground and harness.
How to fix DHW sensor short error on PEERLESS PureFire PF-210?
If your PEERLESS Boiler displays the error 'DHW SENSOR SHORT', check the harness and sensor.
How to troubleshoot stack sensor short error on PEERLESS Boiler?
If your PEERLESS Boiler displays the error 'STACK SENSOR SHORT', check the harness and sensor.
What to do if PEERLESS PureFire PF-210 showing low water?
If your PEERLESS Boiler displays 'LOW WATER', check the boiler water level, low water cut-off, and harness. If a LWCO is not used, a jumper should be placed between terminals #9 and #10, LWCO Contact.
How to troubleshoot high return temp on PEERLESS PureFire PF-210 Boiler?
If your PEERLESS Boiler displays 'HIGH RETURN TEMP', check for reversed supply and return piping or a pump installed backwards.
Why is the return higher than supply on my PEERLESS PureFire PF-210 Boiler?
If you see 'RETURN HIGHER THAN SUPPLY' on your PEERLESS Boiler, check the system piping to ensure water enters the return connection and exits the supply connection correctly. Also, compare the supply thermistor reading to the temperature gauge; if they don’t match, replace the supply thermistor.
