Not the best day for this to happen.

Check the system pressure and top up if necessary - but after that the best advice is to get the people who fitted it for you to come out and sort it - These Worcester combis usually have a 5 year parts warranty and with a boiler that's just a few weeks old, you oughyt to be able to get the labour for nothing as well. It would be a shame to throw those benefits away by tinkering yourself.

SOURCE: I have a Bosch AquaStar 2400ES-NG, Error Code EA

There are three electrodes (connected next to each other by a single piece of metal) that run up into the heat exchanger. They are situated behind the black plastic air intake in the lower half of the unit. Pull out the electrodes and clean them off with steel wool or fine sand paper. Also take the opportunity to blow the dust out of the inside of the unit and clean out the air intake.

SOURCE: Bosch SX 250 tankless water heater will attempt to

This is also known as a flame rectification sensor. It basically is what the computer board uses to detect if the pilot flame is lit. When it makes an attempt to fire is there any evidence of flame ignition? This error does not mean that the sensor is bad for sure. The error could be caused because the water heater is only making three attempts to fire and then shutting down. These water heaters are very complex and have many sensors,valves, ect that are all controlled by a computer board. Some of the basic things to check for are... Make sure that you have plenty of gas pressure. These units have a built-in pressure switch and will have issues if they are starved of gas. Most of these tankless water heaters are up to 400,000 btus and a half inch gas line or undersized connector won't work well. You can also check and make sure there is no pipe dope are debris stuck in the screen inside the gas line where it enters unit. Inspect the pilot assembly for debris or obstructions and try to blow out with compressed air. Also look for any loose electrical connectors on the board or to the sensors...one may have come loose.

Thanks for that mike, it is a worcester bosch combi 24cdi heating and water can stay on for an hour then everything goes off and the red light flashes. it will come straight back on when reset, but then...


Check the pressure reading, should be about 1 bar when system is cold. Various models in the range of 24cdi. If you do not have a manual, go to,
http://www.centralheating.co.uk/Boiler-Manuals/worcester-bosch-boiler-manuals/worcester-bosch-discontinued-boiler-manuals.
Get the manual for your unit, to wards the end of install manual it has a fault finder, Also has a basic 1 in the user manual. Number of flashes how fast the light flashes which one flashing can all mean different, So get the manual and check, Some parts are easy to fix, as long as you do not touch the gas side the rest is plumbing. Come back if needed.

Model Aquastar 250 is not running and is showing an error code of EA. What can be the problem?


  1. Verify that all manual gas shut off valves are open.
  2. Verify gas type (See Fig. 2 in installation manual) corresponds with the type of gas supplied to the heater.
  3. Reset error code and open a water tap to cycle the heater in an effort to purge air from gas line (especially 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. Verify the three yellow wire connections to the set of electrodes (underside of the burner assembly) are secure.
  5. Verify gas pressure meets specifications outlined in chapter 3.8. See Bulletin TWH-G2-03.
  6. Verify venting meets specifications outlined in chapter 3.6 of the installation manual. Improper venting may cause premature failure of the flame sensor rod.
  7. 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 not, Call Bosch Water Heating with observations. Readings from above gas pressure test will be req

My worcester bosch 28 si 11 series is fireing up on heating and systematicaly every couple of seconds turning the flame down to half flame then turning back up to full flame and the spark electrodes are...


This could well be a fan relay fault on the pcb, as in if the fan is cutting in and out it's triggering the pressure switch which in turn is sending confusing signals to the ignition and gas valve. Have you removed the controls connector cover and observed the righthand of the two little white boxes in the middle of the control board (pcb) with the boiler switched on? (be careful because it's live i.e DO NOT TOUCH ANYTHING) Is it sparking?
