Join the DUX club for flame outs, funny noises and pilot light problems.

Purchased from bunnings in 2012 and over much of the time installed made many noises whilst heating up the water (close to bedroom on outside, no sleeping till water has heated up) Now looking at the other reviews, definitely a design or component problem with these units. Peered inside unit, problems with pilot light, controller faulty and melted insulation with black soot. Not worth the risk with these units. Previous Rheem unit lasted 18 years till it leaked.

Purchased in August 2021 at Bunnings Warehouse for $1,149.00.

I purchased the Dux prodigy 5 in 2014. The past 2 years I’ve had constant flame outs with the pilot not staying on. Now it has burned the insulation outside.

Purchased in September 2021 at Tradelink for $800.00.

Flue damper issue?

published

At the 3 year mark the pilot light kept going out and we couldn’t relight so replaced the thermocouple. After a month the pilot light get going out, plumber said it is a known issue with this model. Interesting to read so many bad reviews on line with the same problem!

More like a cold water system.

published

Be bought this house 2 years ago and in the last 12 months the pilot lights has gone out so many times I’ve lost count! Once again today no hot water. So I re-lit the pilot at lunchtime and it’s gone out again now. And now it’s my problem that Dux manufacture products that just don’t work.

Broke after 3 years!

published

My DUX Prodigy 5 Gas Hot Water System broke after 3 years of service. I previously had a Rheem which lasted me 10 years. It only broke because of a tank issue so I expected the DUX to last me until the tank warranty, this was not the case unfortunately.
The gas keeps cutting off after less than a minute of turning it on, I think the problem is the thermostat because I keep hearing a clicking sound whenever the flame cuts off. I contacted a plumber that will be looking at it tomorrow, am dreading the cost as these things can cost a lot. REALLY DISAPPOINTED WITH THIS PURCHASE.

Dangerous Product

published

I purchased this through bunnings on May 2014. Two days back it failed to work. The cost to replace the pilot valve is $400. I noticed the rigifoam packing surrounded the cylinder were melted. When I called them they said it's out of warranty. This is a manufacturing fault. not a wear and tear. They said they can provide the packing but we need to pay for the plumber to get it fixed. I decided to install a new aquamax heater.

Dangerous product.

published

Do not buy! Dangerous product. We purchased this product less than 3 years ago. Last week due to an internal fault with one of the parts, it caught fire. The pilot light would not stay lit, and our plumber has told us we were risking electrocution by attempting to relight it. When contacted Dux refused to offer any assistance.

Absolute scam

published

Brought a Dux 135L hot water service in 2014. Pilot light started going out a few months ago and not relighting. Had a plumber in. Could maybe fix it for $650-$750 but advised if we wanted reliability we should purchase a new unit. Contacted Dux to see if there was anything we could do about getting some compensation and they didn't want to know about it - absolute worst customer service - we are now out $1500 for the new unit. Don't know how they keep getting away with it. Do not buy this product!!!

Do not buy a Dux Prodigy water heater...

published

This heater is good, when it works. Too unreliable. After 4 callouts in 4 years I gave up and bought another brand. The plumber I called for the last breakdown said they were over complicated, unreliable rubbish and to get rid of it. So I did. I am quite annoyed to have to buy a new heater after only 4 years but I think it is a case of good riddance.

So Dissapointed

published

We bought Prodigy 5 135D5N in September 2016 and the pilot light just won't stay on. It goes out every 2-3 days and I have to restart it manually. After spending almost $2000 and being charged for the installation twice I'm so angry. Called service people they promised to call me back but never did .. I mean its still under warranty I don't understand why they won't help me

I wouldn't recommend buying a Dux HWS

published

I had a Dux HWS installed in 2012 which has recently stopped heating the water on a number of occasions. After paying over $100 for if to be fixed three times and the plumber not being able to pinpoint the fault, I think it's time to cut my losses and invest in a new HWS, I will not be choosing a Dux this time. The service department were of no help, pointing out that the warranty only lasts for 1 year.

To many cold showers.

published

After only two years we started having issues with the pilot light going out. In its third year the pilot light was refusing to stay on and we spent over $300 on a weekend call out. The plumber replaces the pilot thermostat but told me if it keeps happening it may be the flu damper at the top of the unit. He said they are too expensive to bother with so just jam it open. a month later and another cold shower. So now I've jammed open the patented energy saving flu damper. Just hoping that fixes it.

Prodigy 5 135D5N

Bought my Dux prodigy 5 135 liter hot water system in May 2015. Now I find there is steam coming out from the top. Called a service technician, he changed the anode, and hot and cold water pressure taps. There was also water dripping from inside the unit. The dripping stopped for a while and there was no more steam until 24 hrs later I hear dripping and the pilot light keeps going out. Well the problem is the flue damper is stuffed and does not open. the flame for heating was as flat as a pancake, when I manually opened the flue the flame rounded the way it is supposed to be, the dripping was moisture build up because the flue would not open when the heater was heating. I am not happy for 3 years and its proving to be a problem. what make this worse is i lost my job in dec 2017 and I'm still unemployed and i wont be able to buy another heater. Dux water heater. How do i get rid of the steam?

Hi Tom,
Is there hot water coming from the PTR valve?

Landlord
Landlord

Hi Tom,

PTR valve, up top, to drain, should only release water from excessive temp or pressure. If no release then probably faulty or low adjusted thermostat. Turn off power to HWS at switchboard. Remove 2 screws on lower cover. Thermostat is upper, element below. Look at adjustable temperature setting on thermostat, turn up if necessary. If already above minimum and water is colder than setting (allow +/- 5-10*) most likely faulty. Possibly faulty heating element but they usually work or not at all if open circuit. if it heats up at all then its probably OK. Replacement thermostats are only around $25 on ebay, then get sparky to install. Just clip mounts on surface and no need to drain tank.

Good luck.

Sorry Tom if your HWS is gas.
No idea about Dux model numbers and presumed it was electric.
