How to fix my Worcester green star ri boiler?


The gurgling sound sounds like you have gotten air into the system. Try purging the air out at the bleeder valves. Also check and make sure that your water inlet is working.

It often flashes ea or af and doesnt want to light


Before calling service technician, open following links for troubleshoot resources including common error codes, Bosch contact information, link to service manuals, and possible product manual
http://waterheatertimer.org/Troubleshoot-Bosch-Tankless-water-heater.html
http://www.boschhotwater.com/HelpfulResources/TechnicalSupport/BoschAquaStarModels/2400ESTechSupport/Troubleshooting/tabid/1295/Default.aspx

Call Bosch 800-642-3111
Multiple error codes can mean PC board failure.
AF might be A9, but not sure.
EA is 'no flame ionization detected with water flow'
  1. Verify that all manual gas shut off valves are open.
  2. Check gas type.
  3. 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.
  4. Check three wire connections to ignition group on the lower front of the heat exchanger are secure.
  5. Check gas pressure.
  6. Check venting specifications are met. Improper venting may cause premature failure of the flame sensor rod.
  7. Check that the minimum power fan speed has been adjusted to the proper value.
  8. 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 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...

FVD interface failure is flashing. How do I reset the water heater?


Is it flashing 2-3? Try this: You can reset the control by unplugging the blower during start up, leave unplugged for at least 5 seconds, plug back in and within 30 seconds cycle temp control from hot to low 6 times.

Rheem Power Vent 2 water heater is flashing 4 times and there is no hot water. Model # 41VRP50NT What can I do to fix this? Do I need to call a plumber?


The flashing light is a trouble sequence light. Find your manual to see what 4 flashes means. It's usually attached to the side of the water heater tank. Try a quick fix by unplugging the power vent and see what happens.

I have a noritz water tankless heater and hot water stopped. Red light blinking three times. Need help.


Three flashes typically indicates the unit is overheating due to scale. I'd try a descale initially and see if that remedies the problem.
