To address a low flame signal on your Honeywell Water Heater, consider the following: * Check the spark/flame sense rod for any buildup of silicone-dioxide. * Check the spark/flame sense wire insulation.
What to do if Honeywell Water Heater gives ECO Limit Lockout error?
If your Honeywell Water Heater displays an ECO Limit Lockout error (water temperature exceeds TCO), the control enters permanent lockout after three ECO events. Reset the control by turning the Setpoint knob to its minimum setting for at least 30 seconds, then return the knob to the desired temperature. This limit should not be reached under normal conditions, so check the installation to ensure all manufacturer recommendations were followed. You may also reduce the setpoint temperature to keep the maximum water temperature further away from the ECO trip point.
What to do if my Honeywell Water Heater has Soft Lockout - Failed Trial For Ignition?
If your Honeywell Water Heater experiences a Soft Lockout due to a Failed Trial For Ignition, first check the gas supply. If the appliance hasn't been used for a while, ensure air is purged from the gas lines. If the pilot flame lights but the control still locks out (6-1 flash), inspect the flame rod for silicone-dioxide buildup. If you have the tools, check the flame signal strength. If the pilot lights but the flame sense issue persists, consider replacing the control.
What to do if Honeywell WV4262B has Soft Lockout - Recycle Limit - Flame Lost?
If your Honeywell Water Heater shows a Soft Lockout - Recycle Limit because the flame was lost, check the pilot flame to make sure the main flame isn't lifting it away from the flame sense rod. Also, check the gas supply to ensure pressure is maintained when the main burner lights.
What to do if Honeywell Water Heater detects FVS Fault?
If your Honeywell Water Heater indicates an FVS Fault, first verify the Flammable Vapor Sensor (FVS) is connected. Then, check that the FVS resistance is not below 1.0 K?. Inspect the wiring to the FVS to ensure it is not shorted. If all these checks are okay, you may need to replace the control.
What to do if Honeywell WV4262B Water Heater detects Valve Fault?
If your Honeywell Water Heater shows a Valve Fault Detected error, first verify that the valve is not wet or physically damaged. Try resetting the control using the ON/OFF switch. If the 8-4 error persists, consider replacing the gas control.
What to do if Honeywell WV4262B Water Heater has Soft Lockout - Recycle Limit - Flame Lost, End Switch Failure?
If your Honeywell Water Heater displays a Soft Lockout - Recycle Limit due to Flame Lost and End Switch Failure, check the wiring of the damper and end switch.
What to do if Honeywell WV4262B Water Heater detects Electronics Fault?
If your Honeywell Water Heater displays an Electronics Fault Detected error, first verify that the control is not wet or physically damaged. Try resetting the control with the ON/OFF switch. If the 8-3 error persists, replace the electronics module.
What to do if Honeywell Water Heater has Flame Out Of Sequence?
If your Honeywell Water Heater experiences a Flame Out Of Sequence issue, check for a pilot flame. If the pilot flame is present when the gas valve should be off, replace the control.
What to do if Honeywell Water Heater has Soft Lockout - Flame out of Sequence Sensed?
If your Honeywell Water Heater shows a Soft Lockout because a Flame out of Sequence was Sensed, check that the pilot flame does not linger after the valves close.
