What to do if the high pressure/temperature alarm pilot light is on in my CleaverBrooks WB Boiler?

  If the high pressure/temperature alarm pilot light is on in your CleaverBrooks Boiler, it could be because the pressure or temperature has exceeded the setpoint on either the auto reset limit control or the manual reset limit control. If it’s the auto reset, allow the pressure/temperature to fall below the setpoint. If it’s the manual reset, allow the pressure/temperature to fall and then depress the reset button. If necessary, raise the setting, but do not exceed the design limit or manual reset setting.

How to fix a CleaverBrooks Boiler when the pilot switch is on but the pilot light is off?
- Y
  Yolanda WatersAug 5, 2025
  If the pilot switch is set to 'power on' but the pilot light is off on your CleaverBrooks Boiler, there are several potential causes. First, ensure the main power supply is energized. If that's not the issue, check if the control transformer fuse is blown and replace it after checking for loose connections. The control transformer itself might be inoperative, so inspect wiring and connections, and replace the transformer if needed. Lastly, the pilot light may be burned out; check for loose connections and replace the light.

What to do if the low water alarm pilot light is on in my CleaverBrooks WB Boiler?

  If the low water alarm pilot light is on in your CleaverBrooks Boiler, it could be due to several reasons related to the water level or the low water cutoff (LWCO) system. Here's what to check: * **Float-type LWCO:** Ensure the unit has the correct water level and that the LWCO line is at the proper level. Also, verify that the float blocking plug has been removed and perform a blow-down of the float cage. Make sure the switch plate operates freely. * **Probe-type LWCO:** Check for loose connections or improper wiring. Ensure the unit has the correct water level. If the probe or relay is faulty, replace it.

Why don't all the steps energize on my CleaverBrooks WB Boiler?

  Kimberly JonesAug 13, 2025
  If your CleaverBrooks Boiler steps do not all energize, the step control may be faulty, requiring replacement. Alternatively, the contactor coil could be inoperative; check for loose coil connections and replace the contactor if necessary. Finally, step control relays might be faulty; ensure the relay is tight in the socket and replace it if needed.

What to do if contactors aren't energized on my CleaverBrooks WB Boiler?

  If the control power pilot light is on, but the alarm pilot lights are off and the contactors are not energized in your CleaverBrooks Boiler, the alarm pilot lights might be burned out, so replace them. Another cause might be a blown step control fuse, in which case you should replace the fuse. Also, the pressure/temperature control may be improperly wired to the step control; check the wiring against the control literature and the unit wiring diagram.

Why aren't the steps drawing rated current on my CleaverBrooks WB Boiler?
- Z
  Zachary WilliamsAug 22, 2025
  If the steps on your CleaverBrooks Boiler do not draw the rated current, it could be due to blown branch circuit fuse(s). Check the element(s) for proper ohms and resistance to ground, then replace the fuse(s). Another possible cause is improper element bussing. Verify that the element bussing matches the wiring diagram.

Why are the contactors noisy (chatter) in my CleaverBrooks Boiler?
- B
  Barbara RobertsAug 27, 2025
  If the contactors on your CleaverBrooks Boiler are noisy (chatter), it could be due to open element(s). Replace any faulty element(s). Alternatively, the contactors may be damp or dirty. In this case, blow out the contactors with compressed air, or remove, disassemble, clean, and then replace the contactor.
