Why won't the display come on and heat my water? Everything worked for two showers. Now won't come on at all

Asked by: Me
you need to reset heating elements, turn power off, take cover off and do not drop it, there is a cable attached, heating elements have a button on each, push them in. put cover back on, power it up. incoming water is running faster than 4.4 gpm, slow incoming rate down

Customer Reviews

220-Volt Self-Modulating 18 kW, 4.4 GPM Multiple Points of Use Tankless Electric Water Heater is rated 3.6 out of 5 by 61.
Rated 1 out of 5 by from terrible unit I purchased this Marey unit and have had issue after issue. The unit I purchased came broken. I of course found that out after my plumber charged me to install it. I also of course had to pay the cost of installing new electrical (you need 100 dedicated amps) and various other fittings needed to make the unit work. I then had to remove this unit and re-install my old water heater. I contacted Marey and I had to pay to ship my unit back to them even though it came broken. As I didn’t have much choice I did that. A “new” unit came without any instructions, had clear water marks on the exterior, and had none of the original packaging. After paying my plumber to come out again and spending more money at Home Depot the unit did not work. Jason (who works at Marey) told me the heating coils were not working properly. Marey now wants me to send them my unit and they will again send me another unit. That means I have to pay the plumber two more times. HEED MY ADVICE AND DO NOT BUY THIS UNIT!

Rated 4 out of 5 by from Good Choice to a standard waterheater The product performs perfectly as described....but. A couple of things could have been better explained in the description and there is a way that it performs better that varies from what people used to tanked water heaters are familiar with. If you are pre-preparing for its arrival you need to know that it IS 100amps, but that it is two double pole 50amp circuit's, so that's four power wires and a ground. And when you're running it don't set the temperature to the maximum or it will cycle through "over heating" a lot. Set it down one notch and it works perfect. And when you run a shower, turn it all the way up for a few seconds and then down to where you normally run it. it will heat up faster that way. Remember this is not a tanked water heater, so there are different rules. Other than that, which I consider part of my learning curve, it is the best decision I've made for home improvement in quite a while.

Rated 1 out of 5 by from Wired and plumbed correctly adequate water flow and pressures. Could not take a shower without it... Wired and plumbed correctly adequate water flow and pressures. Could not take a shower without it getting cold and nothing else being used. Bathrooms and kitchen faucet worked fine by there selves 2 faucets together will not even get warm. States you should be able to get 4.4 gall on per minute and wouldn't even get a gallon per minute of warm not hot water. Very displeased with the misleading information about this product. Carried back for refund. Customer service hung up 2 times. That's enough for me. And I hope everyone hears about my anger with Marey . I don't even want to give the 1 star rating but I can't submit without doing it.

Rated 1 out of 5 by from I have contacted the company, so far we are disappointed... I have contacted the company, so far we are disappointed as the water gets hot, but only stays hot for 2-3 minutes. It will run cold for 2-3 minutes and get hot again. I have found that if I turn the water off as soon as I feel it cooling down and count to ten, turn it back on, it will warm up faster than waiting 2-3 minutes during it's cold cycle. The company seems responsive and we are working with them. So, right now the jury is out on my satisfaction.

Rated 1 out of 5 by from Marey electric water heater This tank is not a really good tank. If you live where the water temperature gets extremely cold I would not recommend this tankless hot water heater when I purchase my home this electric hot water heater was in there and when the Inlet water gets too cold the Overflow light comes on and you will not be able to get any hot water.

Rated 5 out of 5 by from Best heating! This is a great heater: I can set up the output temperature and no matter the water flow it keeps heating the water at the same temperature! We could run 3 showers at the same time, which is a rare occasion but we needed one as the whole family had to go out and the water heater kept the heating capacity just fine! It was easy to install as its size fitted so well that we saved space for other stuff we wanted to keep in the closet. Definitely recommend it.
