Question about Terminator Aquastar 125FX Tankless Water Heater: FX Hood Horizontal Vent

1 Answer

Gradual decrease in water temperature

My aquastar is approx 6 years old. The water temperature has gradually decreased over time with the same inlet temperature. The unit lights correctly. It is a natural gas unit. I have never performed any maintenance. Any ideas?

Rebuild the watervalve or replace it. 6 year old unit means its probably one of the 125 series. Probably a polymer gray water valve. Pay attention to the venturi, most likely its very dirty. You can get instructions off the www.boschhotwater.com websight to rebuild this.

Actually E2 means the water is too cold. P2 is a computer program setting.

Check the connection of the temp sensor itself, maybe its broke on the inside if a new temp sensor didnt fix the problem.

Bosch Tankless HW Heater...Hot water flow becomes cold then hot again during shower. Have had only Bosch plumber in area out numberous times but never fixes the problem.


You are using a low flow shower head. you probably own the 250/2400 they have activation rate of .8gpm. If your shower head is low like this, your unit will deactivate. Higher flow shower head is a fix, or pull the aerator out of the shower head you have now might help.

Your water in southern california is very hot during the summer months. I would try pulling the aerators out of the sinks and shower heads and also pull the inlet screen out of the watervalve connection on the heater itself

What error code do you get? I listed the Bosh telephone number below. They should be able to walk through it with you and diagnose it. Be prepared for long hold times though. I also listed the web site. There you can download the manuals and such. Good luck.

I'm not sure what water cooling system you speak of. This is a propane water heater. Possible issues: pressure regulator making noise. Could be dirty or defective. Air in a water line. Excessive scale caused by hard water.

these heaters work when a pressure drop is sensed in the water supply line. The pressure sensor is likely blocked with sediment from the city supply. You may want to call for service.
