AO Smith Vertex GPH, Customer Satisfaction & Repair History
I see the AO Smith Vertex GPHE-50 has been out for a few years now and I would like to know if anyone has had any experience with installation and reliability.
unsatisfied Vertex AOS owner/installer
Serene...I know it's been several months since your post but I had to try replying. We have the same Vertex, installed in December of 2008 with the same clogging issue that hasn't ceased. In fact, we get a call every 3-6 months because of a failure/no hot water/no heat only to discover another clog. Each time we've contacted AOS and we've received the same answers..."the unit requires cleaning and maintenance". The first time the problem created a circuit board failure and the entire CB had to be replaced. Most recently we're receiving blower prover failure messages. Today there was another error, blower prover switch - removed the switch and it has water it in. blew the water out and the unit started up.
It's annoying because we've installed Polaris units in three other homes and have never had a callback, no cleaning or maintenance. The Vertex on the other hand has shed several cups worth of this "rust" with no explanation or solution.
Does your unit continue to become blocked? Tomorrow I will call about getting a new blower prover switch. Winters still here in upstate NY, can't afford to not have heat and hot water.
Very unhappy and regretted buying this heater
Installed one in my basement (where all my heaters etc are located) about 8 months ago and the display board connection was completely corroded and malfunctioned. Tried to contact AO Smith for warranty and was told that the unit could not be installed in a humid environment so they would not cover any warranty. The humidity in my basement averaged about 40% but can be as high as 50-60% on some days since it is connected by a crawl space to the outdoors. I was told that this was a sensitive electronic equipment and should be installed and treated as such like computers. Nothing in the specification said that. The display board was completely exposed inside the plastic enclosure. Now I have to pay close to $300 for the parts and $ 240 for 2 trips of the technician since no one carried this part. Should have just bought conventional water heater. Who would have thought this thing is so fragile. My last conventional water heater lasted 10 years with no problem.
Bad Hot Surface Igniter Just Replaced
I have had the GDHE-50 for about 6 months now and the hot water stopped working. AO Smith sent someone out within 24 hours and they replaced the Hot Surface Igniter for free. 6 years parts and 1 year labor covered it.

Other than that this unit has been a complete rockstar. 3 showers and a bath going at the same time in a 3,000 SF house and no shortage of hot water. My old 75 gal standard water heater was garbage and would last maybe one or two showers before somebody had to wait another hour. No chance of filling the jacuzzi bath but now it is all very easy.
