Why stoped my Cointra 10 gas heater suddenly to heat the water? After about one year we found less water output from the heater, and then the equipment suddenly stoped.


I am not familiar with the model. Is this a 10 gallon water heater? the volume of water can not change. The temperature can usually be adjusted and even placed in vacation mode. Also the pilot light might be out, this would be the only thing I could think of that would stop all hot water. You mentioned output. If you are referring to flow this would be a restriction in you pipes possibly. If you have old galvanized pipes this would explain the reduction in flow. Also if this is a tankless water heater a reduction in flow would explain in not working at all. If the flow of water is not adequate enough a tankless heater will now turn on. If it is a Tankless water heater then there is a filter located on the cold side. To check this turn off the cold water, relieve the pressure by piping the TPRV Valve "Temperature, Pressure Relief Valve. Then take the cover off the filter. clean all that nasty gunk off the filter, reinstall it and you are back in business. The heater should be as good as new.

How to Change the Gas Valve and Thermostat on a Hot Water Heater


<p>If you are having<b> trouble with the temperatures</b> of your <b>gas hot water heater</b> fluctuating too much, or after <b>changing the thermocouple</b> of your gas <b>hot water heater</b> then you may need to change the complete <b>gas valve and thermostat assembly</b>. Also if you have changed the <b>thermocouple</b> and the pilot still will not stay lit, then the gas valve could be bad or the <b>ECO (Emergency Cutout)</b> may have activated and is open. This is a onetime device and cannot be replaced.<br /> <p><br /> <p>These instructions are for the older style <b>gas valve and thermostat combination</b>. These commonly have a large red knob that adjusts the temperature of the water. Also note that the burner tube nut for <b>natural gas</b> is right hand thread, but if you have <b>LP or propane gas</b> the burner tube nut is left hand thread.<br /> <p><br /> <p>The newer <b>gas valve thermostat combinations</b> that have come out recently are similar, but they have a well in the tank that the sensor slides into. The assembly is held fast with a set screw. With this type of <b>gas valve and thermostat unit </b>the tank does not need to be drained, but most of the rest of the change out is similar.<br /><br />To change a <b>gas hot water heater thermostat</b> you will need to first buy a new gas valve for your <b>hot water heater</b>. The <b>gas valve</b> and the <b>thermostat</b> are integrated into one unit.<br /><br />To <b>replace the thermostat on a gas hot water heater</b> you must follow these procedures....<br /><br />1. Turn off the incoming water and<b> drain the hot water heater</b>.<br /><br />2. Remove the <b>pilot tube</b>, the <b>burner gas tube</b> and the thermocouple from the gas valve. Turn off the <b>gas line</b> and remove from the gas valve.<br /><br />3. Get a <b>pump pliers</b> or a<b> wrench</b> in behind the gas valve and turn the whole assembly CCW to remove it from the tank.<br /><br />4. After applying pipe dope or tape to the new gas valve threads, turn the new gas valve into the tank by turning in a CW direction. Be careful not to damage the small wires to the <b>ECO</b>. They are the little red wires on the back. If you break them the assembly is irreparably damaged.<br /><br />5. Reinstall the gas line, thermocouple, burner tube, and the pilot tube to the gas valve.<br /><br />6. Fill tank with water. Make sure to open a <b>hot water faucet</b> and <b>purge all air from the tank.<br /><br /></b>7. <b>Check for leaks</b> where the gas line hooks up with soapy water.<br /><br />8. Relight pilot light and check operation.<br /><br />9. Set the new temperature setting to a medium setting and then adjust the temperature to your liking from there and adequate time for heating completely<br /> <p>

Cointra electric water heater (5 years old). Leaking water through base panel. No T & P Valve visible. I have emptied it and removed the base panel but am not sure whether to refill and observe or just...


Usually, this means that the water tank is leaking. It is not worthwhile to fix the leakage unless you have welding equipment. Just buy a new one.

Cointra godesia water heater... works perfectly but only for 5 mins then pilot goes out... u can relight straight away and it works for 5 mins again .. this boiler I have just bought new ... j


In my experience thermocouple either work or they do not.when a water heater runs for a length of time before the interupter cuts the pilot or on some modules safety cut out sensor also known as over heat thermostat cuts the gas supply the problem can normally be found in the flue restricting the disposal of waste products of the combustion or the lach of air flow through the appliance

50 gal. reliance electric heater. Water is getting way too hot and the settings were not changed. elements must be working for the water to be so hot. My guess would be the thermostat(s) since it won't...


Thermostats is in need of replacement and sounds like they are sticking. So it would be best to change both out. Turn power off to change them out it would be best for safety issues to change out as soon as you could. I have seen thermostats burn up in compartment on water heater.

Water heater needs a jump-start every morning


Hi,
Did they change the thermocaouple or the gas valve/thermostat???
My gues is that they changed the thermocouple and NOT the gas valve which also has the thermostat in it.

The gas valve is the problem... make them change that or give you a new hot water heater.
