Question about Bosch Water Heaters

Aquastar 1600H. Why is there no spark?

Hydrogenerator is OK, 3 VAC coming out. I got no spark/light/unit function when shorting the male end of the wire connecting to the microswitch.

How do i know if the control unit is bad on an aquastar 1600H


That voltage does not seem high enough. Supposed to be 1.6 VAC and I got 2.5 VAC. Do you have the water flow turned to the maximum? Is there something blocking water flow? The hydro voltage should be checked separetly from everything else, so if you can't get the VAC higher, my guess would be that's the problem.

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.

Tubing size


Absolutely not. Unless it is installed exactly as instructed you will have a problem. Too small of a line = reduced flow rate.
