I have recently had the dreaded i30 error on my Favorit 40860 (model S) and solved it, so I thought I would share my experience.
The error message means that water has somehow escaped from the machine. Enough of it will have collected in the very bottom of the machine and triggered a device. All that the device is, is a piece of polystyrene which floats when too much water has collected. This floating in turns triggers a switch which causes the error. The cute thing about the error, though, is that it automatically triggers the machine to pump out the remaining water in the machine. Helpful.
To reset your machine you can cancel the cycle it is on. I did this by turning off and on, opening the door and then pressing the 30 Min and Intensive Care 70 buttons on the front simultaneously (which are my model’s two buttons to press to cancel the cycle).
So, after turning off the electrics, I pulled my machine out from its place under the work surface and placed a couple of old towels on the floor at the rear of the machine. I then tipped the machine backwards at about 45 degrees and then a bit sideways. All that you are doing is moving water around in the tray at the bottom of the machine in the hope of getting some of it to spill out of the machine – thus allowing the polystyrene float to go down a bit and stop triggering the gizmo which then causes the i30 error.
If you are lucky, and the cause of your ‘leak’ is not a defective part the tipping over trick may work and that is all you need to do. In my case it wasn’t because when I started the machine again, the i30 error arose again. I now had to find the cause.
So, I reset the machine again and tipped it over again – the intention this time being to watch what was going on inside the machine.
I used the excellent instructions on this page (http://www.fixya.com/support/t136292-fix_error_code_30) posted by ‘anguscw’ to remove the top, lower-front, right-hand side, and small lower back panels.
Briefly, you will need a screwdriver with torx bits (star shaped). Remove the top panel by undoing the 2 screws at rear top, then push the top backwards and lift it off. Then remove the small curved panel at the front base of the machine – it is not held in by any screws, it just needs a push to the left – it can help to see what you’re doing if you open the door. Then remove the right side panel – there are 2 screws at the top, 3 on the back edge and one on the front edge (at the bottom). My advice is to keep a note of which screws come from which holes because they are not all the same. You will find that the front edge of this right-hand panel is wedged inside some trim. It’s not held in but quite stiff to get out. I just slid it upwards with a little encouragement. I then removed the small panel at the back (bottom). At this point it should only be held in with one screw (to the left-hand side panel) because you’ve already removed the one on the right. You should now have good access to the inner workings of the machine and see lots of pipes and wires. A torch will be handy.
What I then did was to start up the machine and watch (from a distance since electricity and water don’t mix) for leaks. Sure enough I soon spotted one and after a minute of water hissing out of a perished pipe, the i30 error was triggered and the machine pumped itself dry.
In my case, the cause was a leak on a 3” long piece of rubber tubing that forms part of a stiff plastic ‘arm’ which recirculates water into the back of the machine (where it gets forced into the upper spray arm). The rubber tubing is held onto a steel tube which is part of some electrical device (maybe a pump – I don’t know).
The rubber tubing and plastic arm are all one piece. The arm is also held in place by a plastic tie (to the frame of the machine) and by a [ shaped device on the back of the machine. The [ shaped piece of plastic (red in my case) does not seem removable without destroying it. It pushes onto some metal studs which form part of the rear panel of the machine. Be careful at removing this red plastic thing as I am not sure how much force it would take to rip the studs out of the panel and leave you with two holes in the back of your machine. I snapped my red thing off with a pair of pliers and then ‘unscrewed’ the two broken halves. (The replacement red part (see below) is just pushed on when you come to mending).
To get the rubber tubing off the pump (if that is what it is), you will need some large pliers or better still a clamp to release the pressure on the clip holding the tubing onto the pump. I used a small G clamp.
As far as replacements go, I got mine direct from Electrolux. I had to buy the plastic arm (plus tubing – all one part) along with a new red [ thing and also a new rubber seal for the inside of the machine (although I didn’t actually replace that in the end as the existing one if fine) since they all came as one ‘part’.
Electrolux website is http://shop.electrolux.co.uk/node535.aspx
It will help if you have the product number code (PNC) from your machine. This is actually the code for your machine, not the part you need. You will find it on the inside edge of the door. You need the first 9 digits (mine were 911 232 750).
The website will then tell you your model number and the parts available. I then clicked on Hydraulic System. If you then click on Explosion View it will show you a very handy diagram of the parts related to the ‘hydraulic system’ - http://procornerpdf.electrolux.com/static/Pictures/Views/N5911/2005026.PDF
This is really useful since there are no diagrams to accompany the actual parts that they list as being available to buy. Although I had guessed from the parts list that I probably needed the ‘Rising Tube’, being able to see it on the diagram and match the part number with their list of available parts was very useful.
The bit I needed was component number 145 (Rising Tube, Complete) which comprised the tube itself plus the red [ thing (number 527A) and the rubber seal (130A) which I didn’t really need.
In all it cost me around £25 including postage. I ordered on a Friday and it arrived on the following Thursday. So less than a week of washing up before the dishwasher was up and running again ! And a whole lot cheaper than calling out an engineer which is what AEG’s Customer Care Department (to whom the instruction manual refer you to) said I should do !
