For about a year my boiler (baxi solo HE18) periodically locks out, works ok after resetting for another couple of weeks before doing again then again before reset doesn't work.
Engineer comes out, cleans electrodes which seem pretty clean when he showed me and all works well again for 3-4 months before the whole thing starts again, engineer been out 3-4 times now and the time between visits is getting shorter, last done a couple of weeks ago and had first lock out red light yesterday . Should the electrodes be replaced do you think or could it be something else? Thanks in advance
