How do I deleate the change filter light?


My model is the psp511lca but it may be the same type of reset. I have a dial I turn to the "change filter" option and then press the up and down temperature buttons simultaneously and hold for a few seconds. When you turn the dial back to "run" the change filter light on the display is gone.

Water won't stay hot long


1) Thermostat may be bad, or out of calibration. Set temperature higher, and/or troubleshoot by type of gas control.
Copy following link to troubleshoot by type of gas control valve:

2) Dip tube broken

3) Water leak running hot water out of tank.
Turn off all taps and put ear against pipe listening for water leak.

No hot water, checked ohms on both heat elements,top is 13.8 bottom is 13.4. i have 122volts to both elements and i played around with the heat adjustment on both top and bottom. over time could rusty well...


Marathon elements are specific to that water heater and can be ordered online, but generally are not at the local hardware.
Good to keep a couple spares around.
Marathon is 240Volt water heater.
Thermostats turn off one leg of the 240Volt circuit, so elements and themostats will always test for 120volts.
You removed wires off elements and tested each for continuity and tests showed elements to be good.
Test top two screws of upper thermostat and make sure you are getting 240V to the water heater.

If water heater has some hot water, then that says water heater is getting 240V, upper element is good, and remaining suspects are bad thermostats, bad lower element, or sediment build-up, or combination.

Open following link for troubleshoot run-down:
http://waterheatertimer.org/How-to-troubleshoot-electric-water-heater.html

Water well.
If you have sediment build-up that reaches lower element, then water does not circulate around the element and water heater no longer heats very fast or accurately. If sediment is the problem, sooner or later the lower element will burn out.
Doesn't hurt to flush out the tank now and then, and vacuum out the sediment if that is problem.

Hi I have a Bosch water wizard 10p & although i have the heat turned up to the highest it is still not hot enough! I was wondering if there was another way of increasing the water temp?


Open following link for Bosch troubleshooting resources:
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html

Typical Bosch 10P manual shows temperature control illustration on Pg4, and includes low water temperatures on troubleshoot on Pg6
http://waterheatertimer.org/pdf/Bosch_10P-installation.pdf
Water flow rate too high, low gas pressure, faulty thermostat.

Two other things might be causing problem

No heat the water.


Suddenly no hot water: Red reset button tripped, circuit breaker tripped, bad upper element, bad thermostat, loose wire, TP valve is running hot water out of tank, leaking faucet is running hot water out of tank.

1) Check for leaks.
2) Check circuit breaker.
3) Open top cover on water heater and push in red reset button.
If reset is popped out and will not reset, replace thermostat:
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
4) Test upper element:
http://waterheatertimer.org/How-to-test-water-heater-element.html
5) Loose wire

We have a White-Rodgers 90 series thermostat that started beeping last night. We have had it for about 4 years. Does it have a battery? I couldn't find anything about that in the manual.


Susan, the "90" series of thermostats covers a couple of different thermostats made by White-Rodgers. Here's how to find your model number. With that info, I can check the manual specific to your thermostat.

In the mean time, check the display for the word BATTERY or BAT. (Flashing) on the display. Battery flashing or blinking on the digital display indicates low batteries. If the batteries have recently been changed and the thermostat continues to indicate low batteries, use a pencil eraser to polish each of the battery contacts inside the back of the thermostat. Do not bend them up and down when polishing or you might break them. When complete, they should all be as shiny as a mirror. This will assure proper battery back-up, allow the backlight to work correctly and remove the flashing battery symbol from the screen. Battery (Solid) on Display The battery symbol (not blinking) indicates a loss of power (24 volts) from the heating and cooling equipment to the thermostat. Normally the heating and cooling do not operate when the battery indicator is on. If the battery indicator is on, check the fuses or breakers, make sure the furnace is switched on, and verify the blower compartment door is closed properly. The battery display is designed to indicate the thermostat is running on batteries, so replacing batteries has no effect on the indicator. See No Heat/No Cool for more information. Note: Some heat only systems (zoned systems) disconnect power from the thermostat during a normal heating cycle and display the battery symbol. Millivolt heating systems always indicate battery because they do not supply 24 volts to the thermostat.

A beep often is provided as audible feedback when keys are depressed on many thermostats. You should check to make sure that no key is stuck in the "in" position or is otherwise activated.

Themostat is bad


If water heater thermostat is bad, buy a generic thermostat at hardware store and install it according to instructions shown on link below:
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html
I usually replace both upper and lower thermostats for about $28.
Lowes sells thermostats and elements.
If your water heater is a single-element/ single-thermostat, you can buy any thermostat with red reset button.
Technically a single-element thermostat has 1 less screw, but either thermostat will work.
If your water heater is 120V or 240V, the same thermostat will work of either voltage.
This is true because the thermostat is a simple bi-metal heat-reading device that does not operate on electric current.

That being said, you might want to test parts before replacing anything, in case problem is element.
To do comprehensive electric water heater troubleshoot:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

Image below shows generic thermostat with reset button. Each of these will work for single-element or dual-element tanks with either 120V or 240V. Wires connect just as they did on old thermostat. Tighten wires very tight. Press in reset button to make sure ECO is set. Put insulation and cover back over thermostat when finished.

Circuit breaker in water heater will not reset.


If I understand correctly the red reset button or ECO located on upper thermostat will not reset.
Add a comment if problem is different.

Electric water heaters are fully repairable by homeowner.
If circuit breaker to water heater will not reset, then you need full troubleshoot using inexpensive multi-meter from Home Depot::
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

If reset button will not reset, then two things can cause this problem.
1) Ground short between upper thermostat and upper element, including shorted upper element.
a) Look at wires to see visible signs of high heat and burning.
b) Test upper element for short.
http://waterheatertimer.org/How-to-test-water-heater-element.html

2) Upper thermostat is bad. Test upper thermostat, or just replace thermostat using generic upper thermostat from hardware store.
http://waterheatertimer.org/How-to-replace-thermostat-on-electric-water-heater.html

3) If problems persist:
Troubleshoot electric water heater using inexpensive multi-meter from Home Depot:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html


Upper thermostats are generic unless you have "energy-smart" water heater that has control box and reset button located on top of tank.

Central haeting keeps turning on when itself


Change your air filter, if the system has to work too hard, it will over heat. If the filter is allowing air flow and the system still shuts off it is the thermostat. Keep in mind the Thermostat gauges the temperature where the thermostat is located, if its next to a running fireplace it will think your entire house is that temp.
