We installed the 170D5N about 4years and for the last week or so we have been having alot of cold showers as the flame keeps going out. Extremely disappointing start to the Christmas holidays.

I had my 170D5N installed in my new house by the builder around March 2014; for the past 6 months it has had constant flame outs with the pilot not staying on, I also found that the insulation outside it has burned, unfortunately we have been through difficult situations and cannot afford to pay for a plumber to fix it and we cannot even think about buying a new one, we expected more from this product and are extremely disappointed.

We bought this unit 170D5N from Bunnings with complete installation as we expected to have a very reliable product. It's being nearly 4 years now. Scince very beginning it has issue of pilot lamp going off and as I'm usually out for work my wife and young kids hd to suffer a lot.
We complained and complined even I filed a complaint last week at Dux website and so far no reply.
We cannot aford to buy a new one and I have no idea how to get it fixed as tried.
I'm seriously concerned if this product is safe to use we have to keep it at max for longer period for hot water and I can see it's foam around has started melting.
What I can think is that it was a bad choice we made while trusting the name of Dux and Bunnings

Model Dix Prodigy 5 170D5N SN 15070845076H Scorching at bottom from stuck divertor flaps. Reported by Inspector Order 302250698 and Plumbing repairers. Known design weakness of this model. Do not buy. Item design can cause auto combustion and fire. Gas supply to my house was disconnected and Dux avoiding responsibility for their design as many users have this problem and they keep resolving under warranty. Bought in 07/2015 with 10Y warranty. Have been out of hot water for 4 days now.

I can’t rate it lower. Got installed approx Nov 2015. A year of so later pilot light keeps going off. Called dux but there is only a one year warranty.Now it turns off all throughout the day. Looks like the foam inside it has disentagrated as well. Going to be a fun winter having to go out at 530 in the morning to switch it on. Not happy

Terrible hot water unit. Poor Quality!

Had this system installed since mid 2015 and have always had an issue with the pilot light going off all the time. Always thought that it is normal and have been relighting as usual until yesterday the pilot light does not work anymore. Plumber have advise there is many problems with Dux as a whole. The polystyrene in the unit has also burnt off.

Wish there was -1 to rate this useless product. Had so many issues with this hot water system. With a toddler in the house, this is the worst nightmare in winter days. Spent multiple repair costs on parts and almost looking like the issues never go away. Dux service has been next to nothing.

It can’t provide basic demand. Forget extended usage
Th pilot light goes off all the time. Every plumber who walked in to repair said how bad the system is as a whole.

Doesn’t do water hot enoughWhat a joke I had to relight pilot 200 time in last 2 days now I have no idea that should I spand money to repair as I read comments and reviews on site

I moved in 4 years ago and change 1 old Dux for a new one as the old one was off often. The new Dux 5 170L has been installed by licensed plumber for less than 3 years and it has problem; foam around burning!

Absolutely useless. Had to re-light pilot 20 times I 2 days !!! HAs a manufacture dates of December 2014 and was installed in 2015. Spoke to Customer Care...this was a joke. Thermacouple ect only has a warranty for 2 YEARS !!!! Family member had exactly same problem and dumped the Dux....unfortunately it was after I installed my unit

This came with the house we built. Montgomery Homes, The house is 3 years old and we have to have relit approx. 30 times. The first sign of trouble was within 3 months and we are now up to 1 shower and it goes out. Would not recommend to anyone.

This system caught on fire !!! We only built our house in 2015. We had no problems until one day it just caught on fire.
It only comes with 1 year warranty. There are several reviews the same. It’s disgusting.
I don’t know how these guys are still in business.

Just after 1 year moving to new home, worst problem ever had is no hot water because of this system. I had to call the plumber (who recommended by Dux) several times and spent lot of money on this. No point wasting further money and decided to remove totally and install a new system. Today also I spent $185 and the plumber told need to install another part cost more than $500. Just after the plumber left, it went off again. Sorry to everyone who got Dux HWS.

This is the second unit in 3 years, builder had to replace original unit 2 days after installation as cylinder unit was leaking badly, this second unit has gone through 3 tempering valves in 12 months, now the entire unit has corroded and water leaking as well as gas as the pilot light has gone out, also looks like the foam has been smouldering. Very dangerous units.

Purchased Dux Prodigy 5 in September 2014, it was ok to start with but have now had to replace the unit as problems with the pilot lighter. The manual said, "This is your assurance that you have purchased the highest quality hot water heater available, one that will provide continuous hot water for all your needs - safely for many years to come." What is disappointment! Our unit wasn't even 3 years old before we had to replace it. I won't be buying a Dux product anytime soon.
