Dux Prodigy 3 has been discontinued. See all Dux Gas Hot Water Storage Systems.
My hot water tank is 5 years old and for the last 3 years I have had to relight the pilot light every few weeks. For no reason the pilot light goes out & of course I don’t know until I have a cold shower. Two plumbers cannot work out why it occurs & of course it is out of warranty. Phone calls to the company have resulted in them telling me i need a plumber as “it shouldn’t be happening”. Needless to say I would never use Dux again. Absolute rubbish.
Purchased in August 2015.
Terrible quality and customer service
Bought a Prodigy gas hot water heater just over 7 years ago and the tank rusted from the inside out. Was a couple of months out of warranty. Poor quality product, save your money and go elsewhere.
Purchased in May 2013.
Only 4 years old and needs replacing
As previous people the pilot light kept going out and I couldn't get it to restart. Cost of plumber each time. Unit is now leaking and only 4 years old - needs replacing. Costly exercise! Very disappointed.
Purchased in April 2016.
This is a bad company don't buy
my dux 170l hotwater serice is rubbish.only 2.5years old and pilot light keeps going out.this is known problem so should be covered by waranty. i rang them and was told rudely i might add that it is not albeit it is known problem and said bad luck.i am now going to pursue this in court as it is not good enough.this people dont care but will take your money
shame on you dux. will never buy anything from this so called aussie business again
people please take heed before you buy a water heater from dux as they are rubbish and will cost you s fortune to repair.
Not fit for purpose -- don't buy it
Same complaint as everyone else. Pilot light won't stay on.
In December 2014, Dux fitted a shield to protect it from rain. This made it slightly better -- pilot light only went out in heavy rain. Where I live, it rains a lot. Dux told me they would charge me for call out under guarantee if I complained about the pilot light again.
It got worse. In the last 6 months it's gone from monthly to daily. In the last 7 days, I have spent hours on the phone and paid out $400. New controller -- made no difference. New regulator -- made no difference. ...
Purchased in 2008 and nothing but trouble. Solar panels replaced under 2 years, Anti Frost Valve 1 time, Solenoid Valve 2 times, Gas Control 2 times, Electronic Control unit 6 months ago and now is not heating up. Use up water & gas wont automatically reheat quickly. Its winter & solar is affected but gas should automatically kick in and do the job but same problem every year. Absolute rubbish.
Dux (or Dud) Prodigy. Never again...
Dangerous unit. Out of warranty (2 years old). Pilot continually went out, and when we managed to get it to stay alight, flames randomly shooting up through front of unit damaging internal components. My local licenced plumber took a look noting when lit, gas was escaping inside the unit causing mini "thumps" as escaped gas was igniting internally. Claimed he'd never seen anything like it in his 20 years of plumbing and called Dux to ask if the unit was possibly subject to a recall. Dux advised no, but sent out their contractor to repair it at ...a cost of $350.00 the following day. Unit was not replaced and fire damage clearly visibly up through the front of the unit, but I trusted the plumber and accepted the $350.00 fix. Issue of pilot going out and flames shooting up through face of unit returned however less than 12 hours after Dux's "fix". Called Dux immediately next morning to complain, who had their contractor call me an hour later to say they couldn't have anyone out to look at it until the following day. So this amounted to more than 48 hours without hot water in the middle of winter from the time the problem was first reported to Dux, or attempt to relight it at the risk of fire or worse still, an explosion. Needless to say, we went without the hot water, but rather than wait yet another 24 hours for Dux's understaffed contractor (Cavana Plumbing) to take a second look, decided to get my local plumber in to replace it. I now own the favourably reviewed Aquamax 390 which my plumber also swears by, and am now sleeping much better at night knowing the Dux unit is no longer on my property.
Simple fix for Pilot Light going out
I've experienced the exact same problem described with the pilot light failing to stay ignited in a 6 year old 170L Dux Prodigy 3 but have found a very simple and free solution!
The background is similar, I turned the gas off to replace the sacrificial anode but then found I couldn't get the pilot light to stay on. I had tried to change the anode the day before (but didn't have the right sized socket) and had switched off the gas but was able to turn it back on without issue. I then realised the difference between the two times was that when...I successfully changed the anode I drained the tank completely as the tank shifted a little when I was tightening the anode and it was too heavy to move while it was full of water. My theory was that the thermostat is normally probing the tank which is usually hot and in turn is keeping the thermostat components warm. So here's the fix. Get a blow dryer and heat up the thermostat especially the part below the red dial until it is nice and warm and voila pilot light will light and stay lit! I had been pulling my hair out for 24 hours and had even changed the pilot light thermocouple (fortunately a cheap part at $26) with no luck. I had just debated with my wife about ordering a new thermostat and being without hot water for another few days or just getting a better quality hot water tank and had decided on the latter when this idea hit me. I hope it can help a few more people and shame on Dux for not fixing this clearly defective thermostat irrespective of age of the unit.
Dux = RUBBISH!
Prodigy 3, pilot light goes out daily. 2 warranty calls to Dux with no result. Rang Dux again, out of warranty, only 1 record of me calling so not a recurring issue. Would advise everyone to steer clear of all Dux products as the quality is non existent along with the customer service.
Dux Prodigy 135D5L
We built a new house mid 2013. Have a Dux propane system to heat the water. Everytime we get a new LPG cylinder delivered, the unit develops a problem with the pilot light. Wouldn't stay on so we had a gas fitter out and he said it was a problem in the systems line. Now the Unit won't light at all. Will either be a thermocoupling problem or issue with the thermostat controller. This unit is garbage. Costs us at least $350 to get a plumber out everytime. If you buy one, on your own head be it. It will cost less to replace it with a decent unit in the long term. Never again.
Absolute piece of rubbish and terrible customer service at Dux
We noticed the hot water in our Protégé 3 model wasn't lasting as long as it was previously without any difference in usage. Luke warm showers at best. We checked it and there was no obvious problems. ie: pilot on, temp set to maximum. The system was manufactured in 2013 so not even 2 years old and that's when I found out the warranty is only for 12 months and only covers the parts and the workmanship. The warranty is worth nothing as far as I'm concerned. It's a piece of junk if it only lasts 2 years. Most people expect their hot water system ...to last for 10 years at least. the very unhelpful customer service lady did little to help my anger . Her only comment was we would have to contact a plumber to find out what the problem is. I will tell everyone not to touch the Dux hot water system. It's absolute rubbish. Quite possibly the worst product on the market
Ongoing problems with hot water system.
Worst product on market, replaced contoller twice , first under warranty , solar panels leaking, cost nearly a thousand dollars for labour.
Now pilot light on, but not working again. So far had paid over $ 1k just for service in about six years. Would NEVER touch their product again.
Amazingly bad product
My Prodigy 3 is 6.5 years old. First time its control unit broke several days after warranty expiration. It did not keep the pilot light on. In 5.5 years after its replacement the same has happened again. It seems that it is due to the same crappy unit. I could imagine that Dux who is aware of this problem would invest some resources in developing a new reliable unit but after searching in the Internet has come to the conclusion that my idea is wrong.
Besides the failed control unit my system has two more problems. It almost continuously em...its the sound of dropping water that is very annoying during the night time and one of its 3 solar panels is covered by some dirt inside that looks like black mold. Most probably it means that it lost tightness and some humidity penetrated inside it. I would not recommend to anyone to have such system installed. April 22nd 2016 Update: "Attention to Dux Prodigy 3 Owners Having Pilot Light Problem"
Never buy Dux again
Unit not even 3 years old and now it's got same problem as other reviews! Pilot will not stay lit!, called dux n got told too bad. But they happy to ask for $120.00 just for turning up to look at it plus extra touch it n for parts!! From looking on net, this seems to be a common fault with this type of unit n more or less a way of dux making extra money! . Once a great Australian company with top products but now just rubbish, poor products to go hand in hand with poor service. Shame Dux , I never buy your hot water or air con units again. 1 star is still to hight .
Dux Prodigy Three problems
Have had the Dux Prodigy three 135s for 19 months and the pilot light went out and would not remain lit . Called out plumber of 16 years and he tested everything including thermocouple and found that it was the Gas valve (SIT Valve) this was not remaining magnetized inside to retain the gas flow. of course this is no longer under warranty and a Dux plumber wanted $250 just to come out and then $50 for the first 15 minutes and then the part is about $350 dollars!!!!! how can a part like this go after only 19 months. i am extremely disappointed w...ith Dux and their total lack of interest in fixing everything. Heard that this is a regular occurrence with this part now hope Dux will come to the party for us......don't want to pay almost as much to fix as i did for the original unit!!!! Get Dux to fix
Giving away Dux Prodigy 3 can be found on street curb.
Unit 3 years old, Pilot kept going out, cleaned pilot changed thermocouple, still had problem so called a plumber, Thermostat faulty. was going to be $350 to replace, That plus reading reviews while trying to fix earlier problems I decided to scrap heater and go instantaneous. Thank you Dux you cost me good money...
Removed fairly easily
Feel ripped off
Yet again our rubbish Dux has let us down. This time the pressure release valve on the roof started leaking and cost us $400 to replace! We installed the system in 2008 and have had to get a plumber in at least once a year. I could have nearly have replaced the entire unit for the money I have spent on it.
Arrived dented, Dux sent me a new cover and a gift card. I was expecting a replacement. Then the pipe between the two panels bursts about once a year, finally the roof valve started leaking. I have spent over $1000 on it so far and it’s not even five years old.
Our first problem starts with the valve switch for gas locked, spent $330 for replacement september 2011 then there is water leaking from the solar panel, both two panels replaced December 2012 costing us $440.
Now on Christmas day, found out that the gas is switched off, unable to restart, therefore, this means that the gas valve switch is not working again.
Need to contact DUX on their working day to get their response.
Very dissapointed and this system is costing another hot water unit .
faulty gas switch valve and water leakage solar panel.
Questions & Answers
How can I stop the excessive loud banging/popping noise from the unit. This happens every time the water is being used!!
I don't know why.I too am a consumer.
We'd be happy to assist you with your question.
If you can email through your full name, phone number, address where the unit is installed, model number and serial number of the unit to email@example.com it will be great.
The Dux Team
The heater (as it is a hollow vessel) might be amplifying noises in the plumbing and valves fitted to the cold water supply to the tank, as the water is being drawn off, any 'chattering' of valves is amplified by the hot water system.
It might be worth either getting a local plumber in to test and replace any inlet valves as required, otherwise one of our service agents (contact Dux After Sales on 1300 365 115 Option 2) can change valves as required and inspect the heater for correct operation.
To save you from calling us, we would appreciate if you can email through your full name, phone number, address where the unit is installed, model number and serial number of the unit to firstname.lastname@example.org and we will be the one to get in touch with you.

How long should the hot water last havin a shower.... lasts for about 8 minutes before going cold..... mmmm.... model 135fng...
Hi Craig, this was a regular thing in winter. Shorter sunlight hours or often overcast or just cooler ambient temp in general all contributed. Even though the thermostat should have made gas kick in and get temp up it was often a struggle to more than 10 min of usable hot water with hot tap on full. Eventually we had to get rid of it and installed a 230lt Aquamax and haven’t looked back.
How can I de-scale my Prodigy, the popping and banging is starting to irritate.
