isofast condens 35E displays ignition fault 01?

My isofast condens 35E combi boiler intermittently displays an ignition fault 01 and has been doing since it was installed. To correct it I have to switch the boiler off and back on again. Three plumbers including supposed Saunier duval experts - groupservice have tried unsuccessfully to fix the problem. I suspect it might be due to the fact the boiler is housed in the garage which is operated by a remote control door. There are also 3 other remote control operated garage doors of my neighbours within the range of the boiler. Could the other remote control devices be sending signals to upset the controls or is this a crazy idea. If not, is there any way to hard wire the boiler and abandon the remote control altogether?
