Block error if there is a blocking error, no data will be shown and your boiler will stop working. diff. Enter it below and find out what the fault means. EA There is an error where the pump is not detecting water check pressure gauge and repressurise to 1 bar. When a boiler stops working it generally shows a fault code, or error code. Table 28 Temperature sensor resistance values - 12K. Ground Floor 26 Kings Hill Avenue, Kings Hill, West Malling, Kent ME19 4AE.

However, different models have different fault codes and here at Gregor Heating, we do see three common codes crop up which are:EA (Worcester) or F27 (Vaillant) blocked condensate pipe. What to do if water is leaking through your ceiling, Electric car charging at home: everything you need to know, Short circuit/short to earth in cable harness for the gas valve, Gas valve defective (coils shorted to earth), Flow temperature sensor incorrectly positioned at supply pipe, When the burner starts, the temperature change registered at flow and/or return temperature sensor is non existent or too small, Flow and/or return temperature sensor not in correct position at pipe, Flow and return temperature sensors return implausible values, Flow and return temperature sensors have been inverted, Flow and return temperature sensors have not been correctly fitted. These units all tend to be reliable, but just in case, we have detailed the descriptions of common fault codes for each manufacturer below.Despite this useful information, we would still strongly advise that any further diagnostics or repair is performed by a fully qualified Gas Safe registered company such as Ableforce Services. The mass flow sensor is not connected/disconnected, plug not connected or incorrectly connected, F.53Mass flow sensor fault. gradient: When the burner starts, the temperature change registered at the flow and/or return temperature sensor is non-existent or too small. Insufficient water in product Flow or return temperature sensor not in correct position at pipe, Fault: NTC temp. This is very common with these boilers and usually means the fault is most likely to do with the boilers sensor not being aware that the pump has started running. Rear Office
You may have to wait for the condensate to defrost. If the sensor is out of range the boiler will not operate. All sensors in the boiler are a 12K sensor @77F or 25C curve. The good news is that, more often than not, our boiler can tell us whats wrong with it and it doesnt always require the expertise of a boiler engineer to help get it working again. This could be caused by either moisture in the sump, due to a blocked sump/condensate trap, or a strong wind into the flue, EAFlame was not established during the first 4 seconds of the ignition period. 0117 964 0078, GAS SAFE is the trading name of Gas Safe Bristol Limited.

This website uses cookies. Its always a pain when your boiler stops working, of course, but before you call a qualified boiler engineer to come out and fix it, its a good idea to attempt at least some basic diagnosis of the problem. EAThere is an error because the pump is not detecting water in the system usually this means low pressure, check the pressure gauge and repressurise the boiler to 1 bar. 
Craig left everything clean and tidy and was helpul in explaining the controls. Check the resistor, repeat the gas family check and enter the correct gas family. their homes for over 30 years! Combustion quality outside the permitted range: Wrong gas restrictor, recirculation, wrong gas family, internal pressure measuring point in venturi blocked (do not use lubricant on O-ring in venturi.). Alternatively, click here to get a new boiler quote. Maintenance code this begins with an H and will tell you that there is an issue that will not stop the boiler working but will need the attention of an engineer. This usually appears in extreme cold weather when the outside pipe is frozen. sensor: The line to the water pressure sensor has a short circuit to 5 V/24 V or internal fault in the water pressure sensor, Fault: Pump/ water shortage: Water pressure sensor and/or pump defective, air in the heating installa- tion, insufficient water in the product; connect external expansion vessel to the return, Fault: Flue non-ret.

Whether it's inspiration for your new kitchen, how to bleed a radiator - or even a few things to keep your little one's busy. Visit our, Experiencing problems with your Vaillant boiler? Finance options are offered subject to status and credit check which must be completed before commencement of works. I agree to the Terms & Conditions and Privacy Policy. Most modern boilers will display some kind of fault code. The boiler waits 30 seconds before another attempt is made, An established flame has been extinguished.This could be caused by:moisture in the sump, due to a blocked sump/condensate trap.a strong wind into the flue, Flame not established during the first 4 seconds ignition period.

If the pipe runs outside,pour hot water over the pipeto defrost it, or use your hairdryer. Gas Safe Number: 1818. As a pioneer of the Combi Boiler and still delivering high-quality products, many homes have a Vaillant Boiler installed to serve their heating and hot water requirements. U9, A1 or No code (Worcester), F75 (Vaillant), or F1 (Ideal) low water pressure. Gas family check prematurely terminated. Bristol
Communication fault. Although most new boilers are very reliable, all machines have the potential to encounter a fault at some point in their life. No or too little gas supply pressure, gas valve closed, F.56Fault: Mass flow sensor regulation. Company Number 09477125. This usually requires you to top up your boiler. Whilst these tend to be some of the most reliable boilers available, its still good to know what the issue is if something went wrong. Supply or return NTC short circuited, electronics defective.
