If your Worcester Bosch boiler is showing error code EA in very cold weather it is most likely that your condensation pipe is frozen outside. Pour hot water over the pipe and reset the boiler (Or turn it off and on at the spur switch). If possible put some pipe insulation on condensate pipework. Condensate pipework will be in white, grey or black plastic and around 21mm or 35mm in size.
