Bosch 1600H NG

We installed a Bosch 1600H (natural gas) yesterday. When we first tried to start it we would get a spark but it would not light (the green light would not come on). After about 10-15 minutes of trying different faucets we no longer get a spark.

We know it is getting gas. We reduced the gas flow into the unit from 3/4" to 1/2" because of existing pipes from the previous standard hot water tank. Could this be part of the problem? If not, what else could be wrong?

Thanks!

No spark Bosch tankless GWH 1600 H NG


On a 1600H for god sakes give the Tech the S/N and the color code on the wiring at the flow sensor that starts the hydro sparker. They changed the thing in Mfr and there are 2 different parts. And also rebuild the water valve occasionally like every 3 years as Bosch recommends even if the cover which guides the pushrod is expensive. FYI we now usually buy a new WV as it\'s more reliable than rebuilding and you get all new parts. It\'s like $125 for a WV vs $59-71 for just the WV cover. Also never run these on very hard water fro a long time or you\'ll never descale em without Whitlam and a long wash out.

Possible flow sensor issue. Check to see if your water pressure fluctuates a lot or is fairly steady. These units are sensitive to the pressure. take care.

The manual says to hold a match near the pilot while the ignitor is trying. It says that if the unit lights the pilot orifice may be dirty or clogged. Then the manual says to check the voltage on the igniter. It should be 1.3 volts DC minimum if it is not means the electronic control box is defective.

Bosch 1600H won't work on windy days


The incorporation of an anti-back flow, flue pipe insert may be your solution, also the pilot flame control may need to be adjusted up a little.

Good luck

Problems with bosch 1600h ng tankless wh igniting


I found that the solution to my issue of not igniting was due to a bad pilot electrovalve part #8708501249. It was about a $50 part that was bad from the start.
Really disappointing that Bosch's QA would let a such a defective part ship. I spent about 3 years of using a workaround with a fan blowing air to get ignition until it finally failed. I had a tech look over the system to point me in the right direction.
