I have recently had a new Halstead ACE HE24 combi boiler fitted which has a fault.
The boiler will heat up the radiators and then stop heating when the water gets to the temperature set by the thermostat. But when it tries to relight 10 - 15 minutes later it fails and displays the number 3 (in the manual it states that this can be an indication of low gas pressure but the plumber is convinced that the gas pressure is ok - measured @ 2.7 m3/hr at installation).
The boiler will not relight until it and the radiators have cooled down and the pressure on the gauge is back to approximately 1.5 bar. To relight it, I then have to turn the dial to the reset position & then back to the temperature setting.
The plumber who installed it has came out twice to fix it, but both attempts have been unsuccessful. The part which produces the spark has been replaced and we have tried plugging it in to a number of different electrical sockets just in case the socket it was originally plugged into had reverse polarity or a bad earth.
I have noticed a similar thread on the forum which ended up being a faulty PCB: //www.diynot.com/forums/viewtopic.php?t=21593
I have also emailed Halstead's Service department and will update the thread if I get a useful reply.
Any help with this problem would be very much appreciated and I will forward any advice to the plumber who originally installed the boiler.
