Question about Water Heaters
Fault code EA. i went straight for electrodes and cleaned them as they were very scaled. still did not help. i have checked that the condensate isnt backing up. im a gas registered engineer but the client doesnt have the manual. can you give me any pointers before i go for the gas valve. as it definately is trying its hardest to light before it goes to its fault code.

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.

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.

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.
