Combi pilot light going out.
My boiler has been playing up.
Finally got round to having a look at it today, and when all back together, the pilot light will not stay alight. According to the manual, it is either a faulty thermocouple, or a faulty overheat switch. I'd presume the thermocouple will be the most likely suspect. Am I right in that thinking? And, the universal thermocouples from Screwfix - am I likely to get any joy if I buy one of those in the morning? Thanks Alan. -- To reply by e-mail, change the ' + ' to 'plus'. |

No, it was fine, but I do remember last time it went out that it took ages to get it lit again. This time it doesnt want to know. I was having trouble with the hot water going cold every minute or two.The diagnosis was a blocked secondary heat exchanger, which I took off today to clean, but it didnt seem at all cogged like I was expecting. So flushed it through anyway, put it all back together, and then the pilot wouldnt stay lit. Alan. -- To reply by e-mail, change the ' + ' to 'plus'. |

Have you checked that the pilot light is clean, not sooted up and that the sensor is actually in the flame? Phil B |

Screwfix came to the rescue - I was there queueing at 9:55, and got home at 10:15, a bit of a swine to fit, as the new thermocouple has rather a long tail on it, whereas the old one was only 4" long. After realising that it wouldnt work when touching other metal work, a bit of gentle bending ensued, and it successfully lit, and stayed lit. All working again now, and domestic distress is disappearing, as the daughter couldnt survive the whole day without washing her hair! Ta Alan. -- To reply by e-mail, change the ' + ' to 'plus'. |
