Ok here goes and, no lectures please.
I have recently had cause to change my leisure batteries and when doing so accidentally (as if I would do it on purpose) caught the pos-neg cables.
Didn't think at first any damage anywhere had been done, checked all fuses etc etc and none gone. Went away this weekend and have no heater at all, no on Electric or gas or 230, no lights anywhere.
Checked all fuses I could find again and followed the blink code
46 s,s,l,s,l,l,l,s 1) Control panel Combi or power selector switch Combi E defective 2) Combustion air motor or circulating air motor defective 3) Battery earth to the minus terminal Combi defective 1) Control panel or control panel cable defective - Power selector switch Combi E or control panel connection cable defective 2) Combustion air motor defective - Cable harness defective - Electronics defective (paint spray in control panel socket) - Internal connection between the (+) carbon brushes and/or circulating air motor and circulating air motor casing via carbon dust 3) Earth connection from the power supply is missing 1) Replace Combi control panel / or cable - Replace power selector switch Combi E and or control unit connecting cable 2) Replace circulating air motor 3) Check earth connection (ground cable) of power supply - Check supply line of combustion air motor - black cable for short circuit to ground or red cable for interruption - Replace cable harness - (If cable harness not damaged, replace combustion air motor) Check electronic PCB for paint spray in control panel socket (replace electronic PCB)
However, in view of what occured I am more likely to look at a fuse somewhere and want to know I have located all of them first.
I have obviously checked the fuse board on the main unit and none of these are blown, I have even replaced them all to make sure.
I have then gone to the actual boiler unit and checked the slow blow fuse on the PCB board, and this is also ok.
however I did read there was another one? there was one previously I changed which was really really hidden but is there another anywhere else?
please bare in mind that this boiler is so so unaccesable that I have to pretty much dismantle the kitchen to get to the PCB board and I mean sink out, draws out etc etc.
The van is a Rapido 999m on a merc.
