Bosch AE125 no hot water, blinking light


Hey Andy. Do you have your owners manual? There should be a section near the back that will break down the diagnostic code the flashing light is giving you. If not remove the front cover and look inside should be a wiring diagram and light legend.

Question posted under Bosch tankless.
Question says 'tank'
Brand, model, and type heater unknown.
Elements mean electric.
'Thermal cutout pops when taking shower produces cold water' indicates tankless, since tank-type would maintain some hot water.
No error code might indicate tank-type.
Add a comment with type, brand and model number of heater for possible assistance.

Problem with overheat cutoff. Press reset button on the control panel.
Before calling service technician, open following link for Bosch troubleshoot resources.

Bosch GWH 715 ES flashing EA code. This unit was working fine for over a year so I am assuming gas pressure can't be the problem? The spark is flashing and the unit lights for about 2 seconds then...

Above are the manuals required to diagnose and service your error code.

EA: No flame ionization detected with water flow.
Verify that all manual gas shut off valves are open. Check gas type. Reset error code and open a water tap to cycle the heater in an effort to purge air on new installations. Cycling hot water tap on and off multiple times may be necessary. If heater still faults with EA error code, have a licensed gas technician properly purge air out of the gas line leading to the water heater. Check three wire connections to ignition group on the lower front of the heat exchanger are secure. Check gas pressure. Check venting specifications are met. Improper venting may cause premature failure of the flame sensor rod. Check that the minimum power fan speed has been adjusted to the proper value. Observe inside the viewing window of the heat exchanger when a hot water tap is opened. Sparking should be followed by a steady blue flame. If flame is unstable or yellow with proper gas pressure.

Bosch aquastar Aq125-hx does not produce hot water. Pilot is ok. Gas and Flame heat is ok. water pressure is ok. Just no hot water getting to the faucets. Help.


That particular tankless water heater has hydro-generated ignition. In order for it to function, it requires a certain water pressure and velocity. You can try turning on the hot water in two location in your house to see if that gets it started. If it does, try getting a higher flow shower head, or removing the limiters in your faucets.

Not producing hot water


the only time it's the valve is when you loose pressure on the hot side of any faucet, depending on the age of it you could just call the company bosch and they will tell you how far away a real tech is from you and contact them for you, you do have a 1 year labor 5 year parts warranty with the tankless unit, for you I hope you are within your warranty,,,, if not change it to a rinnai system the will send people to you if you have a problem
