Hello everyone, I installed a Bosch 125FX natural gas water heater in my home in 2005. It has been working well up until a month ago. On one day, I noticed there was no hot water at the kitchen sink. I turned the faucet off and then back on again and everything was fine. A few weeks later, it happened to my wife when she turned the shower on. A few days later it happened again while I happened to be standing near by the heater. The heater goes through its normal "tick, tick, tick" but the burners never ignite. Water flow through the heater is normal and, clearly, it tried to start. I figure it is one of two things:
- The igniter stopped working inspite of the ticking sounds
- The gas valve isn't opening so there is no gas to ignite
This only happens one out of ten or twenty uses so the temporary fix is a quick off-then-on with the faucet. Being busy (and lazy) has kept me from investigating further. Do any of you have any experience with this model? Is there a common failure that causes this particular symptom?
Thanks, Pat
