Alpha boiler repair North London

Symptoms of this job and like many other problems with combination boilers is that once the boiler goes wrong you get neither hot water or heating leaving you right in the dark.

First we check the condition of the boiler which seems to be in good nick with no obvious signs of distress or distortion to the boiler.

We then check there is power to the boiler, which there is and then turn on the boiler listening to the processes which it goes through.

1. We hear the fan and pump start to run.

2. We hear a click which indicates the air pressure switch has connected.

3. We wait for the sound of ignition and the sound of boiler lighting but it don’t

A quick read through the manufactures instructions tells us to check ignition and cables (we found these to look ok) It then tells us to check voltage going to the spark generator from the PCB. At this point we would know if the problem lies with the PCB or the spark generator, if the PCB was sending the correct voltage to the spark generator it would mean the PCB was ok and the spark generator was defective. Multi-meter confirms that the PCB was ok as it was sending the correct voltage and what we needed was the Spark Generator.

A quick phone call from the North London plumber around to the local boiler spares suppliers and we were able to locate the part needed to get this boiler up and running again.

With the new part in possession and ready to fit to the boiler we make sure we isolate the electrics to the boiler before disconnecting any parts. Changing this part is quite straight forward and is just a case of disconnecting the ignition cables and power supply cables coming from the boilers PCB. Unscrew the old one and replace with the new and simply reconnecting the cables back into the correct positions and we are ready to re-assemble the boiler and fire it back up.

Boiler repairs and all over gas related work should only be carried out by competent Gas Safe Registered Engineers and should not be attempted by anyone else.
