If you are saying you instaled it 8 months ago, if you are not licensed you have voided your warranty,,, if you had it installed you do have at a min of 1 year labor and can call your installer, when they started doing the tankless water heater there installers are supposed to go to classes for installing these units and the company's that manafacture them will provide you with assistance on any problem, in your book it will tell you what is wrong on the code page if you don't have the manule go to there website they have all the codes listed,,

http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#delime

If error code will not reset afterwards, then holding both arrow buttons down on remote might reset error code.
Models have changed since this pdf was posted in 2008

If error does not clear, then call Rheem and expect them to try to sell you a service call.

I have a PowerStar tankless electric water heater, model #44-557710 and it was replaced about 3 months ago. This morning I had hot water and this afternoon I do not. When I call for hot water a red light...


Call Bosch. And exercise your 10 year parts warranty rights.
Copy following link for Bosch power star manuals:
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html#Ariston
Check circuit breakers, fully off and then fully back on. Test if voltage is at least 80% rating plate on unit. Check that temperature dial is set correctly. Call for service again.
Don't install tankless computer that heats water. You cannot fix this computer yourself, and they are problematic for owners.
Go to Lowes right now, spend $285 and buy tank-type electric water heater, roll it into your house, and save money, since the electric tankless computer heater costs average $100 more per year to operate than tank-type heater for average family of 4.
Tank type heater can be repaired by homeowner same day for $25 using off-the-shelf parts from hardware store. And that empowers the regular guy, and gets you off the junk tankless treadmill.

Installed a tankless gas hot water heater a few months ago, and ever since then when ever I turn on the hotwater, I get pockets of air coming out of the faucet. There are no leaks in the water lines, but...


1) Never, ever install tankless water heater, unless your wallet is 2" thick and you enjoy nuisance problems and recommended continual maintenance.
2) Add in-line air vent.
http://waterheatertimer.org/images/Air-vent-added-to-return-22.jpg
3) Look for check valve along the line. Look for mixing valve, pressure regulating valve, etc.
4) If you have recirculation system, remove cross-over check valve and see if problem is located there.
5) Contact Rheem. 800-432-8373 They will want model number, serial number, and name of installer. And might recommend contacting installer or plumber.
6) Increase water flow. Check water flow requirement of tankless (.5 gallons per minute activation) with actual flow at faucet.
7) Clean water filter at tankless unit.
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf
8) Crossover at single-handled faucet.
http://waterheatertimer.org/Crossover.html
9) Fix all leaking faucets indoor and outdoor so no air is being sucked in.
10) Bad TP valve on water heater sucking in air each time water pressure pulls on the valve?

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

Read your manual for troubleshooting, advisories and required maintenance.
Tankless are maintenance heavy.
1L means tankless heat exchanger has lime build-up.
De-lime tankless unit.
U-tube has videos for de-liming tankless, but there is more to consider:

De-liming is yearly maintenance requirement.
Tankless are prone to lime build-up
Regular de-liming will not restore full efficiency to tankless unit.
Tankless cannot be exposed to water with more than 11 grains hardness.
Temperatures over 135 can cause minerals in water to harden on metal surfaces of any water heater.

Also clean Tankless water filter each month, and clean and maintain burner and combustion chamber yearly.
The cost of maintenance and cost of expected repairs and cost of parts plus cost of original installation will never pay back the $1-8 monthly savings on gas bill. All costs are energy.
Make sure there is qualified service technician in area before buying tankless.

Upvote the help.
And take advantage of fixya expert assistance live.
For a price, expert works with you while you work on water heater or any do-it-yourself project.
Fixya is always less expensive than a service call.

Thermostat flashes IL ? Model PTG-53PVN


http://www.palomatankless.com/owners/homeowner+trouble.lasso#28-11
The Controller displays error code "1L."
There is a build-up of lime in your Paloma.
Contact your plumber to service the Paloma by flushing out the lime.
Also search u-tube for flushing lime out of tankless.

I am a free answerer, and I specialize in giving you resources for free
The paid answerers may have a person who knows your product and the error codes
The manual will also have the error codes.
The person who installed the unit will also know the error codes (or should know)
Each day I see 20-25 unanswered questions about tankless water heaters.
The number of questions shows the complexity of the machines, and the inability of the manufactures to take care of their customers.
The manufacturer will refer you to the installer.

The link above goes to Rheem tankless water heaters
Click on a product and it opens a page showing many tankless models
Click 'more information' and another page opens with spec sheets and other pdf
Not surprisingly there are no troubleshooting steps or troubleshooting flowcharts
There are plenty of ways to buy a tankless
There are not many ways a do-it-yourselfer can fix a tankless

My Rinnai R85 heater will not heat; it is leaking water. I installed the unit 24-26 months ago, and had no problem until today. The automatic starter will engage but the flame (pilot) will not ignite. The...


I just fixed a leaky R85. Fortunately it's the bypass valve, not the heat exchanger. Did your heater freeze up in this snow storm? Unplug the power, open the cover and see where it leaks. If water comes from the top, means crack on the heat exchanger, then it would be too costly to replace. If you can see the water gushing out of a valve, on the bottom of the heater, then it's an easy fix. The valve is fixable, you don't have to replace it. But still need to find out what causes the flame fail (error 12). I suspect the igniter got wet, dry it with a towel after you take out the valve. Removing the fan first will give you more room to work inside.

the thermostat should be replaced it only has one on the upper eloement, it has the dial on it to set the temp, but if it is only 3 months old it comes with a 1 year parts 6 year tank warranty, if you call whirlpool and tell them about this problem they will have there own teck or sub contractor that they use to come out and fix it for free,,, first go to there web site and put in your serial number and it will tell you how old the unit is, sometimes they sit for a while and are actually out of warranty before it is installed,, also did you install it your self?? if you did di you fill it with water all the way till the water came out of the hot side on your faucet full force before turning on the electric,, if not you have fried the whole unit, you will need to replace both elements and the thermostat, the elements must be completely submerged in water before they have the power turned on,,,
