Okay thank you the error code is for the pump. The pump from what your describing has gone bad. You will need to replace it.

I am not looking instructions to remove the pump. I want to know why but is leaking and wether or not I need to replace it
Plumber: Brian Weeks, Plumber replied 7 months ago
The pump may have gone bad for multiple reasons. The usual two is the impeller in the pump or it has blown a motor winding. You will need to replace the pump, but the exact cause you won’t know till you pull it. With steam coming out sounds like an internal motor seal went bad.

I am sorry not steam, I meant stream of water.

Sorry had an emergency at work
So I’m now trying to remove the pump but can’t release the the back seal
Plumber: Brian Weeks, Plumber replied 7 months ago
That can be tuff some units have screw in the bottom of the box that holds the pump to the unit also.

No there’s a clip holding the rear nipple in place. Are you farmiliar with the Navien systems?
Plumber: Brian Weeks, Plumber replied 7 months ago
I am, once you replace the pump you should be all set. You sound mechanically knowledgeable if you have any more questions let me know

here was the problem:
As I said the water was flowing straight through the circ pump. The reason was the plug at the bottom of the pump fell out. I put it back together and it works fine
Plumber: Brian Weeks, Plumber replied 7 months ago
That’s great news glad it was something simple.
Ask Your Own Plumbing Question
Customer reply replied 7 months ago
it was, we couldn’t see the plug but after the pump was disassembled we realized that there was a plug missing. This is why I asked if you if you were familiar with Navien. I figured, if familiar with it you would have asked about the bottom plug when I described the water flowing out of the pump.
Plumber: Brian Weeks, Plumber replied 7 months ago

i am glad everything worked out. Have a happy holiday.
