Most of these have a safety switch, that would make the pilot shut down. Also check for rust deposits in your fuel line, and pressure.

Pilot light goes out randomly on 6 year old Bosch Aquastar tankless water heater. When I restart it it may work for a day then goes out again.


The pilot light can be blown out just by the main gas being ignited especially if the pilot flame is a little weak. Some times a bit of grit gets into the pilot nozzle reducing the flow and hence a weak flame. Try cleaning the piolt jet nozzle with a fine piece of wire. You may have to dismantle the jet nozzle to clean it properly.

The Pilot burner flame is large & yellow


the pilot is getting too much air and is an indicaiot of dirty or air/ fuel ratio imbalance. The pilot is wimpy and the thermocoupler has alot to do with the gas . Make sure your thermocoupler is on the tip of the flame. You may end up replacing it. because it is showing signs of eminnt failure. When it fals your curners won't fire up. Good luck.

Tankless water heater pilot light will not stay on


It is most likely the water valve stuck open, telling the controls to heat water, that it thinks is flowing through it, but without actual flow it overheats. Depending on how comfortable you are with taking it apart yourself, you could open the valve to see if it just needs cleaned out, or if you have a ruptured diaphragm or some other cause.
