Taylex Septic System Problems: Alarm Codes, Blower and Pump Faults, and What You Can Check

Taylex’s own alarm codes sort septic system problems into four kinds: high water in the tank (often an irrigation-side fault), no air from the blower, a tripped breaker in the blower box, and a blown irrigation fuse. The slow problem the alarm won’t flag is sludge left too long between desludges. The Eco Controller on a current Taylex tells you which fault you have with a flash code, and Taylex’s own manual lets the owner handle a few checks before anyone is called out.

Everything past those checks belongs to a service technician, and the system’s NSW Health accreditation conditions say so. This guide works through each fault using Taylex’s March 2026 owner’s manual, its FAQ page and the NSW guidelines, and covers the older Taylex units still in service on some Hunter acreage. For a brand comparison, see our Fuji Clean vs Taylex review.

Which Taylex do you have?

Current Taylex ABS (Advanced Blower System). A blue or green blower box sits on the tank, with an Eco Control Panel showing a green power light and a red alarm light above a mute button. As at the NSW Health register we checked on 28 September 2026, Taylex has six accredited models: the ABS 1500 in concrete and poly (certificates to 31 December 2030) and four nutrient-reduction ABSNR models (to 31 December 2027).

Older Taylex Industries units. An older Taylex Industries manual covers the Clearwater 90 with a Compact Series controller: an on/off rocker switch, Mute, Reset and Mode buttons (Mode sets a Holiday Mode that runs the aerator 20 minutes an hour), and red or green lights for the aerator, the irrigation fuse and the water level. On that panel the flash codes below do not apply. Go by the lights: a red aerator light means the aerator is disconnected, faulty or the system fuse has blown, and a red water level light means high water.

Taylex’s FAQ says it sells a “Retro Upgrade Kit” to fit a newer energy-efficient blower to older models, including the Taylex Compact and Clearwater 90 Deluxe, and that the kit must be installed by a licensed professional. On an old unit that keeps faulting, ask about it before anyone prices a new system.

Reading the Taylex alarm: what each flash code means

On a current Taylex, the red alarm light flashes a set number of times and the buzzer sounds. The mute button silences it for 24 hours; the light keeps flashing until the fault is fixed.

One oddity: Taylex’s January 2025 manual lists a single flash as normal operation. The March 2026 manual and the current FAQ both list it as a blown irrigation fuse. If you see one flash and hear the buzzer, treat it as a fault and ring your service agent.

For alarm faults common to every brand, see why an AWTS alarm keeps beeping.

3 flashes: high water, usually on the irrigation side

A high-water alarm means water is coming in faster than the irrigation pump is sending it out. Taylex’s manual says it may correct itself when several sources of water arrive at once and overload the system, such as back-to-back washing loads while the showers are running. Wait 15 minutes for the surge to stop. If the sprinklers are running, check again once they stop.

If it is still flashing, Taylex’s manual lists four things to check:

1. The irrigation filter. If one is fitted on the line before the irrigation area, is it blocked?
2. The irrigation line. Is it kinked or broken? Mowers and slashers are hard on above-ground lines.
3. The irrigation pump. Has it failed? If you never see the sprinklers run, suspect the pump.
4. Turf valves (surface irrigation only). Are they all connected? Taylex’s older manuals say to push removable turf keys down hard.

Rain is the other common trigger. Taylex’s FAQ says a 3-flash alarm is not unusual after significant rainfall and asks owners to watch it for 24 hours before calling. You can keep using water during a Code 3, but use as little as you can. Taylex also asks that surface water never pools on or enters the tank, so on heavy Hunter clay check that the ground around the tank still falls away from it.

A failed irrigation pump is a technician job, at $600 to $1,200 installed. The OLG guidelines call for the irrigation disc filter to be cleaned at each quarterly service, and Taylex’s homeowner guide says your service agent will show you how and when to clean a fitted filter between visits. An active high-water alarm with the tank close to overflowing gets a same-day or next-morning response from us.

5 flashes: no air flow and blower problems

The blower supplies the air that keeps the aerobic bacteria alive, so take this one seriously. Taylex’s manual says 5 flashes usually means the blower is not working properly, possibly from a short circuit, and advises calling your local wastewater specialist.

The exception: Taylex’s FAQ says a tank sitting in direct sun on a hot day can set off a 5-flash alarm. Watch it for 24 hours and call if it persists.

Other warning signs:

• Noise. Taylex’s FAQ says you should not hear the blower unless you are standing over the system, and that loud sounds point to a problem.
• The power switches. Taylex’s manual says each switch in the blower box must stay on at all times, or the treatment and the alarms may not work.

Taylex’s March 2026 manual also puts a blower air filter replacement every 12 months on the technician’s schedule. If your service record doesn’t show one, ask.

A replacement blower is $650 to $1,400 installed. Our AWTS air blower replacement cost guide covers what drives that range. We diagnose before we replace: a tripped breaker may need only a reset, and a worn blower diaphragm is a $120 to $250 service kit rather than a new blower.

3 and 5 flashes, power cuts, and the “never switch off” rule

Flashing 3 and 5 together means the 7-amp breaker under the double power point in the blower box has tripped. Taylex’s manual walks the owner through a reset:

1. Remove the 4 screws on the blower box cover.
2. Turn off both switches (switch 1 is the pump, switch 2 is the blower).
3. Push the reset button under the double power point and wait 10 seconds.
4. Turn on switch 1 and wait 10 seconds, then switch 2 and wait 10 seconds.

If the breaker trips as soon as one switch goes back on, the manual says there is a problem with the pump or the blower: leave that switch off and notify your service agent immediately. If the system doesn’t alarm, keep an eye on it for the next 3 days, and if it keeps alarming, call your service agent.

Do the reset once, with dry hands and in dry weather, and go no further. NSW Health’s accreditation guideline says all electrical work on these systems should be done by a licensed electrician, and resetting a breaker again and again won’t fix a faulty pump or blower.

Power cuts. Taylex’s FAQ says the bacteria can survive a short time without air and any smell should clear once the air is back on. If the outage drags on, some Taylex units can run the irrigation pump from a generator, which lets the house keep using the system. Taylex says to check the box on top of the tank: two female connectors means a generator can be used, and one means it can’t. Ask your service agent before you connect anything.

Never switch it off. Taylex’s FAQ says that with the power off the bacteria start dying within about eight hours, the tank goes anaerobic and can smell for a long time, and some tanks have to be pumped out and restarted. The older Clearwater 90 manual adds that switching off can flood the system and void the warranty. Leave it running while you’re away.

Chlorinator, sludge and the quarterly service

The chlorinator. A Taylex disinfects the treated water in its final chamber with a chlorinator before the irrigation pump sends it out. The OLG guidelines say the most common method is chlorine tablets in an erosion feeder, which needs no power, with a free chlorine target of 0.5 to 2.0 mg/L. Topping up the disinfectant and testing free chlorine are part of every service under NSW Health’s conditions, and the OLG notes that cloudier effluent uses much more chlorine. Our guide on how often AWTS chlorine tablets need replacing has more on tablets.

Sludge build-up. Taylex’s March 2026 manual lists a desludge every 3 to 4 years. The NSW rule doesn’t depend on the brand: the OLG guidelines say a tank must be desludged no later than when sludge and scum reach one-third of its depth, or come within 150 mm of the base of the inlet or outlet. The OLG says levels can’t be reliably judged by looking, which is why Taylex lists the sludge level among the quarterly checks.

Two things to know about the desludge itself:

• Refill straight away. The OLG guidelines require an emptied tank to be refilled with water to at least two-thirds full (or to the outlet level) to avoid the tank lifting in wet ground. Taylex’s FAQ puts the volume at roughly 4,000 to 5,000 litres to fill all four chambers to three-quarters full.
• Cost. A full AWTS desludge and pump-out is $450 to $750 with us. It isn’t covered by the quarterly service fee. The waste is transported and disposed of under NSW EPA waste rules at a licensed treatment facility, and you get a disposal docket for every load.

The service contract. Taylex’s FAQ says its systems must be serviced quarterly as a condition of their state accreditation, by licensed wastewater service personnel. NSW Health’s guideline goes further: owners must hold a service contract of at least 12 months with a service agent employed or authorised by the manufacturer, and must not service the system themselves unless the manufacturer authorises them. The agent sends a service report to your council after each visit. Quarterly AWTS servicing with us is $90 to $150 a visit.

What upsets a Taylex

Taylex’s manual names harsh cleaning products and the washing machine as the greatest cause of problems.

• Washing. Spread loads across the week rather than doing it all on one day. Liquid detergents break down more easily than powders.
• Bleach and antibacterials. Keep bleach and harsh chemicals to small doses, no more than once a week. Taylex puts natural antibacterials such as eucalyptus and tea-tree oils on the same list, and its FAQ adds hydrogen peroxide and “Oxi Action” laundry products.
• Drain cleaners and garbage disposals. Taylex advises against caustic drain cleaners (it suggests vinegar and baking soda) and says garbage disposals must not be used with any Taylex ABS.
• Never flush wipes of any kind, sanitary products or nappy liners, and keep cooking oil and food scraps out of the sink.
• Medicines. Don’t pour antibiotics down the drain. If someone in the house is on chemotherapy, Taylex’s FAQ says you don’t need a pump-out straight away. Tell your technician, who decides whether one is needed.
• Access. Don’t cover the tank with decking, soil, mulch or pavers, and keep the grass around it mown.

What you can check, what needs a technician, and what it costs

You can look, listen, reset once and keep the irrigation side clear. Anything inside the tank, the wiring or the pump belongs to the technician. Don’t lift tank lids or reach into a chamber to free a float: gas builds up in a tank that has lost its air, and an on-site tank is not a safe space to lean into.

An after-hours or same-day emergency call adds $150 to $300. Most routine pump-outs are scheduled within 48 hours, with no travel surcharge across the Maitland, Cessnock, Singleton and Port Stephens service corridors.

If your Taylex is flashing and you aren’t sure which group it falls into, call 0468 278 123 and tell us the code. If the tank is close to overflowing, see our emergency septic service.

Frequently Asked Questions

What does 3 flashes mean on a Taylex alarm?

Three flashes on the Eco Controller means the water level in the tank is high, often after a surge of water from the house or heavy rain. Taylex says to wait 15 minutes, then check the irrigation filter, the irrigation line, the pump and the turf valves. After heavy rain it asks owners to watch it for 24 hours and call if it continues.

What does 5 flashes mean on a Taylex?

Five flashes means no air flow, usually a blower fault, and Taylex advises calling your local wastewater specialist. The one exception is a tank sitting in direct sun on a hot day, which Taylex says can trigger the alarm. In that case, monitor it for 24 hours before calling.

Can I turn my Taylex off when I go on holiday?

No. Taylex says the bacteria begin to die within about eight hours without power, the tank turns anaerobic, and restarting it can mean strong odours or even a pump-out. Leave it running while you are away; the bacteria adjust to the lower flow on their own.

How often does a Taylex need desludging?

Taylex’s March 2026 owner’s manual lists a desludge every 3 to 4 years. Under the NSW OLG guidelines, a tank must be desludged no later than when sludge and scum reach one-third of its depth, whatever the brand. Sludge is measured at the quarterly service, and a full desludge with us costs $450 to $750.

Can I service my own Taylex system?

No. NSW Health’s accreditation conditions say an owner must not service the system unless the manufacturer has authorised them, and must hold a service contract of at least 12 months with an authorised service agent. Owners can still do the checks in the Taylex manual, such as the irrigation line, the turf valves and a single breaker reset.

My Taylex is an old Clearwater model. Can it be upgraded?

Taylex says it offers a Retro Upgrade Kit that fits a newer energy-efficient blower to older Taylex models, including the Compact and Clearwater 90 Deluxe. The kit must be installed by a licensed professional. Ask your technician whether it suits your unit.
