My worceser bosch 30cdi conventional condensing boiler is continually in the air purge(flashing flow temp then two 0's) mode even though there is no air in the system, can anyone tell me why, thankyou
now mine is doing the same! - what was your fix mike? Mine is flashing 18 and then the oO display - did you get a fix?

No, but I've got exactly the same problem with mine. My plumber is coming tomorrow (Sun 7th Oct) so if I find out what is wrong then i'll email you back.
