I'm desperate for help and advice
I have a Alpha CD18R....
4 weeks ago (01/11/10) the boiler stopped working and A&B lights were flashing simultaneously. An engineer visited and said we needed a new PCB.
The PCB was changed but the lights still flashed; (note: the PCB board was a different design to the one removed but the engineer rang the manufacturer and was assured that this wasn't a problem and was the correct one for the boiler)
another engineer visited and changed the Fan.
Although the lights stopped flashing, the central heating is still not coming on.
Following the operational sequence in the instructions manual Turn On>(Y)Turn thermostat to max>(Y)pump runs and fan runs>(Y)spark at ignition electrodes for 10 second>(Y)Burner lights>(Y)Burner output modulates until set temp is reached>(Y)Burner goes out>(Y)fan stops after 50secs>(Y)pump continues to run until temp reduces to set temp>(Y).... it says that the operation should be successful; however we are still getting no heating or hot water. the boiler seems to think its got to temp and turns itself off again. then 5 minutes later thinks it needs to turn itself on again! then off again! then on again! but never stays on long enough to actually heat anything
Several engineers have been out... trying several things
a new primary flow sensor
a new primary return temperature sensor
a new pump
cleaned electrodes
checked all pressures
checked and cleaned all filters
checked and cleaned condense drain
checked flue
(note: one engineer noted that the water in the system was a bit dirty and could do with flushing. another engineer noted that the flame on the burner doesn't seem very strong)
but still no joy. The boiler goes through the motions turning itself on then turns off for 5 minutes before going through the whole process again.
At the moment having problems with communication between the insurance company and the manufacturers 🙂confused🙂 and wonder if anyone else out there might be able to help or make other suggestions to try in the mean time!
4 weeks in this cold with a 12month old baby in the house is not at all any fun!
Also, should i turn the boiler off completely or let it keep going through the motions??!!!
As the temp has now dropped to -2 outside is there any worries of our pipes freezing?! anything i can do to avoid this!
any help/ideas/advice gratefully recieved!
