Hey, I've got two smoke machines on the blink at the moment. One is a Martin Junior 700 and the other is an Antari Z-1000. Both have been well used but looked after to a certain extent (correct fluids etc).
The Antari first...
When the controller DIN is moved when it is plugged in and on the green ready light flashes on and off, and a relay inside can be heard to click. When this happens the heater does not come on but the pump will still function so it just squirts fluid. When wiggling it so the green light doesn't come on until it's properly warmed up it works fine. I've replaced the DIN connector on the controller wire and it still does it so I'm thinking it's either the PCB (loose solder somewhere perhaps?) or the DIN plug on the PCB. It is only minute movements that triggers it though.
The Martin now...
The pump has recently packed in, sometime when the pump itself is knocked it'll do a very poor sounding reverse action on power on but it seems to have given up there as well. I've removed the pump and another website I found after a lot of Googling says "The fluid pump is a standard 24V VDO pump". I've spent ages on Google/Froogle and ebay but can't find anything looking like what I've taken out. Does anyone know if it will be easy to find a replacement? Here's a picture of the pump from that site.
Another quick question about the Martin. I think the nozzle is a bit gunked up as it smells quite nasty when it heats up, what should I use to clean it out?
