The machine is later than the ones I reviewed, I reviewed a 2006 and a 2009 version, in that time the old AKO fridge controllers which failed all the time were replaced with Gicar PID units. I asked for pictures more pulled back because the machine looked odd to me…but now I am on the PC and have checked, it’s probably because it’s a later model.
I think the machine may have had some modifications from standard which makes it tricky. I think the wire that’s disconnected might be something to do with low water detection? Does low water detection from the machines plastic tank, work for your machine?
The Gicar PID has tape all over the top ventilation slot, fortunately it looks to have come loose some years ago. That PID is the version with the display and components in a single box and it likes to be cool. This is because the little hahn on board transformers only have a 55C rating. Sometimes they fail and you can desolder them and outboard an external transformer with a bit of bellwire. I did one on a MK1 Izzo Alex Duetto many years ago now…we’re talking over a decade.
The best thing you can do is remove the PID and open it up, have a look. I also wonder what happened to the tape, so look for any signs of water damage as well as a failed transformer on the board.
The PID has that thermistor connection, but one wire seems to be going to the side of the boiler with a bit of tape or something round it? What’s that all about? Is there a join under there that’s been taped up. If it has become disconnected, PID would still work, but give a AL1 AL2 error
