Open Question

I purchased my heater 3 years ago and the first 8 months worked perfect, after that in the middle of the shower stops heating the water and I have to turn off the water and on to have it working again

Is this unit repairable?, where can I get the parts for repair? where can I find the trouble shooting indications?

SOURCE: hello, we have a demand

In most of the tankless water heaters the tempature of the warter is controled by the rate(amount) of vlow of the water passing through the unit. Turn down the flow of water going into the water heater and the water that is still passing through will be hotter. Carefully. A little at a time,so as not to be too hot.

I believe they offer a refund if the 'fix' doesn't work.
The manual might also have troubleshooting.

Each day I see 20-25 unanswered questions about tankless water heaters.
And the day before, there were same number of unanswered questions about tankless products.
The number of questions shows the complexity of the machines, the brand-specific-ness of the problems, and the inability of the manufactures to take care of their customers.
If I understand correctly, the manufacturer will refer you to the installer.
There are not many ways a do-it-yourself-er can fix a tankless.

SOURCE: The unit is no longer heating the water. The red

This will be a thermostat or element problem. The red light tells us that you have power to the unit. If you are handy you can test the thermostat and the element with a continuity tester. A voltmeter may also be used. This will tell you where the fault lies.

My Rheem tankless water heater has been flashing a C8 and 76 code. I can turn off the heater using the power button on the unit, but my hot water will only last for a shower or so. Any suggestions? ...


Before calling service technician, open following link for troubleshoot resources including Rheem chat and contact, possible manual, error codes, etc.:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

C8 76 is generally bad PC board. Call 800-432-8373
Just like a motherboard on your computer, the tankless PC board is operational center of tankless water heater.
Various sensors gather information from water pipes, gas line, vent pipe, and air supply to determine when to activate burner.
Most people understand that when their computer motherboard needs replacement, that computer will probably not work reliably again.

Tankless is basically connecting a complex computer to your plumbing and electrical lines and to a gas burner with a vent pipe to outdoors, despite knowing that plumbing lines, vent pipes, gas burners, and household electrical systems have plenty of problems on their own.

Age factor: When tankless is new and everything operates perfectly, the tankless works correctly.
And each tankless manual recommends yearly and monthly maintenance, just to maintain operation, the cost of which can exceed the expected 1-8$ monthly savings. And who wants to clean the water filter each month and delime the exchanger every year?
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

Don't buy a tankless water heater because the only folks promising unlimited hot water and effortless water heating experience while saving money with a tankless are the tankless promotors.

Solve most tankless problems yourself, same day, any brand for about $350.

My family is moving in...how do i increase hot water availability?


large water heater, turn p the themo stat to a higher setting ( watch for burns with young childern and older folks)

or the best install a tempering valve. this valve mixs hot water with cold water before it goes into the building.

Again if you have young ones or old people they can burn faster than any other group.the best is a larger heater for the DIY person.

Thanks Tom

Bosch water heater keeps getting error EA. We read online that if we ran the hot water in the sink while taking a shower it would stop erroring. We did that and it worked perfect for about 6 months. A...


lower the output temp on the unit. the tap water could be too cold coming in. The bosche units don't like a large temperature difference between tap water and the water at your shower head. Condensation becomes a real problem. I run my water thru my basement slab to heat it up and that made all the difference, but you probably didn't buy your house with a dirt basement did you?

Water turns cold very quickly


I had the EXACT same problem (installed my tankless last winter and worked fine, now this summer it fluctuates, have to turn the shower completely off and then on again to get any hot water and then it only lasts for a couple of minutes!) Argh - it is frustrating!

Here's what I found: the demand for hot water is lower during the summer (hot) months because the "cold" water coming in is already quite warm. You don't need as much hot water to make the shower temp comfortable. SO, my tankless was shutting off due to low flow demand. I've removed the flow restrictor from my shower head and it helped alot but didn't completely solve the prob. Next step is what has been recommended to me by several people but is much more expensive - change the pressure valve on your shower to a temperature valve. Or just wait til winter and it should work ok again :)

Our second unit just failed and needs a new controller more money


The only Bosch tankless I have ever touched have been the 3 I have taken out and replaced with Rinnai. I think Bosch/Paloma/etc. have two problems:

1. They do not properly certify technicians before allowing them to install these units.

2. Their product is mediocre at best.

The biggest problem I've seen is that people don't vent them properly. The last one I pulled out had a combined vent length of 55'. 55 FEET! Absurd!
The units was condensing so much inside the vent that it washed out 2 gas control valves in ONE YEAR.

Buy Rinnai, buy Takagi, buy Noritz....maybe even a Navien (new player...time will tell)
+
Factory certified technicians, preferably equipped to do the gas & plumbing without having to sub it out.
=
Years of trouble-free hot water.

Good Luck.

A humming sound is coming from my gas water heater.


It is probable a lime build up in the bottom of the water heater tank. You can remove the bottom heating element and clean the lime out, keep in mind this sometimes turns into quite a job though. And you may damage the heating element during removal and have to purchase a new element.

Paloma Tankless water heater wont kick on


Tankless Water heaters have a automatic pilot and digital water temperature control system; you have to turn on the water in the house to get it to kick on that is unless you have a circulation pump on a timer. If the gas supply doesn't have atleast a 2" rating that with cause the tankless to malfunction because it's not getting enough gas pressure; certified professionals rarely make this mistake. Moreover, if you don't have a water softener you are using with the tankless you voided your warranty; the minirals clog the heat exchanger.
