Questions & Answers

Does this model XG40S12DM40U0 use the electronic ignition or does it have a standing pilot light...

Does this model XG40S12DM40U0 use the electronic ignition or does it have a standing pilot light? I seeing conflicting info. The User Manual uses the word 'pilot' somewhat ambiguously but the Home Depot description indicates electronic ignition. Which is it?
Asked by: Tim
I believe it does not have a pilot light as I did not see one at the bottom. There is an electronics ignition device (white box) in the front that also adjusts temperature. I do know the unit even though is a gas unit does need 120VAC outlet to power the damper at the top which opens and closes electrically. The unit comes with a cord about 15 ft long.

Performance Platinum 40 Gal. Short 12 Year 40,000 BTU Natural Gas ENERGY STAR Tank Water Heater is rated 4.4 out of 5 by 641.

I purchase it on7/5/2019.had installed the same day and it didn't even work for a second. The pilot could not light. The installer went back to Home Depot and they couldn't help. I called the 866 # and they told me a technician will come out on Monday 7/8/19. When I called on Monday to find what time to expect them, I was so disappointed when they told me that the parts hasn't ever leave the warehouse as yet. Not to mention that it took four transfer before someone could give me an answer and they weren't even customer friendly. I live in Massachusetts where the water stays very cold even in the hottest summer, so my family is not able to take showers without the hot water. the unit was not cheap to begin with and as a result of the problem I HAD TO PAY THE INSTALLER AN EXTRA $75.00 FOR THE EXTRA TIME HE STAYED TRING SOLVE THE PROBLEM.RHEEM PUT A PRODUCE KNOWING THAT THE CUSTOMERS WILL HAVE PROBLEM WITH IT BECAUSE THE FAULT WAS FROM FACTORY AND IS NOT NEW.I BOUGHT THE PRODUCE IN GOOD FAITH BUT,I would recommend anyone even take it for fr

Rated 1 out of 5 by from Disappointed I ordered the water heater online to be shipped to the store. The heater was received almost 3 weeks later defective. Rheem customer service were friendly but the warranty was such a hassle to use. They asked to get my own plumber to fix the problem and get reimbursed later on . My plumber found out it was a problem with the transformer, so I had to call them with the diagnosis to get the defective part shipped to me, which I got overnight, Then my plumber installed it and I had to pay him out of my pocket. Later I emailed them for the reimbursement and they give me a really hard time with the paperwork to the point that I had to ask my plumber to call them directly to confirm my payment. I still didn't get my money yet. it has been almost 3 months since I ordered my heater, I took me a whole month to get the water heater working properly and still waiting for my reimbursement if i'm even getting it.. NOT A GREAT EXPERIENCE..LUCKILY IT WAS IN SUMMER TIME..

Rated 3 out of 5 by from Don't count on the WiFi working I like the water heater, and it has not given me any issues in the year I have owned it. I would have given higher marks were it not for the WiFi feature. The main reason I purchased this unit was for the WiFi and the WiFi has been a MAJOR disappointment. I travel and wanted the ability to manage the water heater remotely, as well as having the system to warn me if there was a water leak. The WiFi feature does NOT work. The smart phone app is finicky and has not worked on the last two times I needed it when I was traveling. Customer Service was not able to correct the issue, which was blamed on their servers, not on the WiFi unit itself. The WiFi was a bungled effort by Rheem and does not reflect the quality of the water heater units. I could have saved myself about $150 dollars by just purchasing the less expensive model without the WiFi, which is what I recommend. If Rheem couldn't do it right, they shouldn't have done it. It was a wasted extra $150 for me.

Rated 2 out of 5 by from 2 years and both will not stay lit...... Have had the hot water heaters for 2 years and both have stopped working. Contacted customer support with a technician at my house and they sent out parts because it was coverd under warranty. The first customer service rep was great. On a follow up call after receiving one of three parts in the mail the second cusomer service person was less than stellar. She continued to tell me I was not giving her the information and telling me what was said on my first conversation with cusomer service but once I gave her both serial numbers she said well I must have not heard them correctly. They are now sending more parts out and I get to have no hot water for a few more days now. Asked if I could get a number to a technision and she said no, if I don't hear from someone in one business day I should call back. That would be a Saturday and they are not open. She then told me I could call Monday, so I get another few days with out hot water. Really, you can't give me a number to your contractor? I have 2 units and both do not work so I have no hot water in my house. I guess the upside is that one is in the attic and the other in the garage and with our temperatures in Texas, I have lukewarm water to shower in. One upside to having tempatures in the 100's!

Rated 1 out of 5 by from Don't get this Heater! We bought this heater 3 months ago. First problem: It has a flammable vapor sensor that detects everything. I mean everything! Including cat litter, soap (if you clean the area near it, the soap vapors will shut off your machine), even dust!!. What happens is this: The thumb-sized sensor detects a vapor in the vicinity and overcharges itself, shutting off the machine. Once this happens, you need to get a new sensor (48 hours) and have it installed. Doing it yourself will void the warranty. If you want a machine that is constantly in need of a plumber to install a new uncharged vapor and want to have no hot water every 12 weeks for 2-3 days, this is your machine. The fact that you need to plug it in should be the first tip off. Even the technicians at Rheem admit that the vapor sensor is a problem. Why they haven't recalled them? Commerce maybe? I'm so sorry I got this heater!
