Brivis TEK304/TEK321/TEK331 LED Faults:

   

LED:	Fault/Meaning:
ALL OFF	If all LEDs are off, this may be completely normal or a fault. It is normal for all LEDs to be off if the heater is in standby, waiting for the thermostat to be turned on. If you power off the mains power to the heater for 10 seconds, then power the heater back on, you should see the LEDs run through a start-up sequence which will last 5-10 seconds or so.  If you see the startup sequence and then all LEDs extinguish, this is normal and just means that the control board isn’t seeing a call for heat from the thermostat (the thermostat may be turned off, the wiring to the thermostat may be damaged somewhere, or the thermostart may be faulty).   If, after powering on the heater at the mains, you do not see any start-up procedure, this will need to be investigated further.  Firstly check that the heater is properly plugged into its powerpoint, and that the powerpoint is switched on.  You can also use a lamp or other small device (eg. a mobile phone charger and phone) to check that there is power at the powerpoint that the heater is normally plugged into.  If there’s no power at the powerpoint, check the distribution panel (fuse board/meter box) for blown fuses and tripped circuit breakers.  If the premises is equipped with fuses rather than circuit breakers, turn off the mains power to the premises before removing or re-installing any fuses. TEK304: Turn off the mains power to the heater and disconnect the heater from its powerpoint.  Remove the large top cover of the electronics enclosure to expose the control board inside.  Locate and check that both of the 2A fuses are intact and not open-circuit. TEK321/331: Turn off the mains power to the heater and disconnect the heater from its powerpoint.  Remove the small top cover to expose the mains voltage electrical connections.  There’s a 2A fuse located on the circuit board inside the control module, in about the middle of the board.  The fuse needs to be inspected and checked for continuity.  Unfortunately, this is probably best done with the control module removed from the heater, as the fuse is in a very awkward position.  Replacing this fuse is also difficult, due to its position and the lack of room to work. Note: It is best to check fuses with a multimeter, as a gap in the filament inside the fuse can sometimes be rather small and difficult to see.  Another thing to be aware of, is that on occasion, the fuse itself can fail inside one of the end caps, which is not usually visible.  If a replacement fuse is required, it should be replaced with a fast-blow 2A 3AG 250V glass or ceramic fuse.  These are available from places such as Jaycar Electronics and Altronics.  Using the incorrect fuse will void your warranty, increase the potential for an electrical fire, and in the event of a short circuit, it will cause more damage than it would have if the correct fuse had of been fitted.  If a blown fuse is found, it is suggested you purchase 3-5 replacements, as you are likely to blow more fuses while trying to locate the short circuit. Care needs to be taken when removing or reinstalling a fuse so that the fuse terminals on the circuit board do not get splayed apart, as this will cause a poor connection.  If the terminals do get splayed apart, they need to be bent back into position so that the fuse is held in snugly.
ALL ON	Solid: The most common reason for all of the LEDs to illuminate and stay on, or to turn on and off at random, is due to an electronic failure.  In the case of electronic failure, you may also hear sporadic clicking, clunking, buzzing and ticking.  The room fan may also start and stop at random.  If the thermostat is turned on and calling for heat, the burners may ignite and extinguish sporadically.  This is the most common type of electronic failure and is repairable. Solid and Flickering (very fast flicker): This is usually due to electronic failure inside the electronic heater controller, but can also be caused by an open-circuit room fan motor.  If the motor is open-circuit or not plugged in, the heater controller will get stuck in its start-up sequence and the LEDs will all come on and flicker very fast.  Even though the room fan motor can cause this issue, it is more likely to be an electronic failure inside the electronic heater controller and not a problem with the room fan motor.
O/HF:	Overheat Condition – Fan (return air/cold) side. Solid: The over-temperature thermostatic switch near the room fan motor inside the heater is open-circuit.  This fault may be caused by a failing/failed room fan motor run capacitor, seized/stalled fan motor, or faulty over-temperature switch.  The burners will extinguish and the room fan should be running while this fault is present. Flashing: Over-temperature Lockout.  The heater is in a safety shutdown due to multiple consecutive over-temperature events.  The heater will not operate while the “O/HF” LED is flashing.
O/HS:	Overheat Condition – Supply Air (hot/outlet) side. Solid: The over-temperature thermostatic switch near the hot air outlet of the heater is open-circuit.  This fault may be caused by restricted air flow causing the heater to overheat, a failing/failed room fan motor run capacitor, seized/stalled room fan motor, collapsed ducting, blocked return air filter, or faulty over-temperature switch.  The burners will extinguish and the room fan should be running while this fault is present. Flashing: Over-temperature Lockout.  The heater is in a safety shutdown due to multiple consecutive over-temperature events.  The heater will not operate while the “O/HS” LED is flashing.
ROLL:	Rollout – The gas flame is burning outside of the combustion chamber inside the heater. Sold: The electronic heater controller has detected that the gas flame is burning outside of the combustion chamber. Flashing: Rollout Lockout.  The electronic heater controller has detected repeated rollout events.  This is a serious safety issue and needs to be looked into by a qualified gasfitter.  A rollout condition may result in an uncontrolled fire inside the heater, heat and/or moisture damage to the gas valve and electronic heater controller, and among other things, it may be a symptom of a defective heat exchanger, which is potentially deadly as it can allow carbon monoxide to enter the premises, which has the potential to cause death.  You can not see or smell carbon monoxide, and very low levels of carbon monoxide will cause health issues, up to and including death. Due to the potentially serious safety issue, the heater will not function if the “ROLL” LED is flashing.  Discontinue using the heater until it has been serviced by a gasfitter.
ALM:	(TEK304 Only): Alarm – A fault has been detected that requires the electronic heater controller to be reset.  The cause will need to be investigated, but it is usually due to too many ignition failures or a flame sensing fault.
EPRL:	(TEK321/TEK331 Only) – Electronic Pilot Re-Light. TEK321: Solid: The electronic heater controller is attempting to re-light the pilot light.  This will only work if the pilot has very recently extinguished and the thermocouple is working and still hot. TEK321: Flashing: A flashing “EPRL” LED means that re-lighting of the pilot has failed and no further attempts will be made until the electronic heater controller is either reset or power-cycled.  The heater will still operate if the pilot is lit.  If the pilot is not lit and the heater receives a call for heat from the thermostat, the heater will blow cold air. TEK331: Solid: The electronic heater controller is waiting for the external ignition module to ignite the pilot.
ECON:	Informational – The heater is running in economy mode.  This requires a heater with a gas valve an thermostat that are both capable of running in economy mode.
FAN:	Informational – The electronic heater controller is sending power to the room fan.  The room fan should be running.  If the room fan is not running, the motor run capacitor may have failed, the bearings in the fan motor may be seized, or the electronic heater controller may have an internal fault.
STAT:	Informational – The thermostat is calling for heat. Solid: The electronic heater controller has detected a call for heat from the thermostat.  A heating cycle should begin or will be in progress. Flashing: Cooling down.  A heating cycle has been completed and the thermostat is no longer calling for heat.
PRES:	(TEK304 Only): Informational – The pressure switch has detected vacuum from the combustion/flue fan.
AOG:	Informational – Appliance Operation Guide. Flashing: The microcontroller inside the electronic heater controller has detected an internal problem and has recovered from it.  This is usually caused by electrical interference from the ignitor/ignition circuitry and is not generally anything to be concerned about.
