You have too much pressure in your system , you have to reduce the pressure or by Valve from Home Depot it holds a lot more then original from your tankless water heater.

Re- set code!!!!
We have a Takagi TH3 DV 540 model.Air intake got blocked with snow, condensation etc.Once we cleared that then you just have to re-set it to clear the 991. On our model there are 4 tiny buttons across the bottom (Take off front cover) to find them. of the computer board assembly bottom left corner. Push the two buttons on the right simultaneously hold for 15-20 seconds or so, then turn the Takagi off then on again- should work now!
If you have a different model then those buttons will be in the bottom left corner still but running vertically- try doing as above with the bottom two buttons. We had to go without heat and hot water for 2 days until we could get hold of someone to tell us this. We called Seneca Supply 716-852-4744. Good luck

How are you filling the tank, and is this in an RV or what? Open pressure relief valve when filling and when water comes out pressure relief valve, you know your close to full. If it doesn't come out there when valve is open, check for by-pass valve(s) in wrong position and not filling the tank.

If no water in it when switch left on for hydro use, you probably burned out the element. They burn out pretty quick when no water. You have to shut off breaker to it for safety, and remove back cover where you see hydro cable going in to access it.
