Why does my Bradford White Water Heater display six flashes, then three flashes, with a three-second pause (Soft lockout)?

  The 'six flashes, then three flashes' error on your Bradford White Water Heater indicates a soft lockout, which could be due to: * Unstable pilot. * Pilot tube blocked or restricted. * Oxidation build up on pilot electrode. * Wire damage to pilot assembly or bad connection at gas valve. * Insufficient combustion air. * Low gas pressure. The system resets automatically after 5 minutes.

What does it mean when my Bradford White D-38T-155 Water Heater shows six flashes, then two flashes, with a three second pause (Soft lockout)?

  If your Bradford White Water Heater is showing six flashes followed by two flashes, with a three-second pause, it signifies a soft lockout. This may be caused by: * Pressure switch tubing kinked or blocked. * Vent blockage or improper vent configuration. * Vent termination being affected by windy conditions. * Blower not spinning up to speed. * Vent temperature too high. * Faulty pressure switch or blower temperature switch. The system is designed to automatically reset after 5 minutes.

  If your Bradford White Water Heater displays an error code of eight flashes followed by three flashes, verify the control is not wet or physically damaged. You can also try resetting the control on/off switch. If the 8?3 error persists, replace the electronic module.

  If your Bradford White Water Heater is showing eight flashes followed by two flashes, with a three-second pause, it could be due to damage to the sensor or wire in the control’s well, or the control’s sensor resistance being out of range. In either case, replace the control.
