1st series Duo-tec, no display...?

[diamondgas]

Hi folks,

Anyone give me a heads up on the above issue? I got a phone call from a landlord and am going there tomorrow!!

There's power to the boiler, apparently, but the display is blank, never had this one until now! Initial thoughts are the PCB fuse &/or the PCB? If it's the fuse does anyone know of a 'specific to this appliance' component that gives this symptom? I'm going with the intentions of checking out the usual suspect, pump, diverter actuator maybe even the gas valve? I've never known of these fan's popping the fuse ... anyhowz ... anyone worked on a load of these babies can give me any further info, resistance readings to expect etc. I'd appreciate it

Thanks in advance,

Steve

sounds like fast fuse blown,i have had 1 blow for no reason but divertor would be my first check if the bush has failed them move on to the usual suspects if it keeps blowing fast fuses

Cheers mark My first port of call is check/replace the fuse then see what happens ... If the fuse is okay and power then I'm assuming the PCB's duff? Would hate for it to be a component taking it out though, Like with the Isar's!!

Exactly what gas man said. Usually the diverter valve leaking on to the momo actuator, causing fast blow fuse to blow.
