Thank you for this Dave.

I only ordered the bearings as YouTube is loaded with videos showing bearing replacement procedures and none of the few I watched warned that welded tubs were a thing.

Now I know I will have to consider whether I go down the new tank, or new machine route.

For the time being I am just going to put it back together and put up with the noise until I decide.

Thanks for taking the time.

Ok, after all this faffing, the fourth engineer to visit spent very little time isolating the issue, although he admitted he had the benefit of knowing all that had gone before.

The simple problem was that the drain hose had fallen down the stand pipe so that its end was submerged in the standing water in the trap. The instant he pulled up on the drain pipe the machine could be heard to take a gasp of air. At that point he said that he was 99{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} sure that that was the cause and as it turns out he was absolutely right.

I cannot see how to change the title of this post to include [Solved], so if a moderator would kindly do that please I would be grateful.

Cheers all.

The engineer attended today and changed the pressure switch. Just ran an Eco cycle and it threw the i11 error at 2 hours in, just as it always does!

I would like to get an opinion from the technical/design team at AEG, but have no way of getting hold of them. I have requested a contact from their service department, but they just pass my question on to me local (generic?) service centre.

Don’t know how to progress this now and the today’s engineer says he’s out of ideas. Inlet solenoid maybe?

you would think so but with what you have had swopped there is not much left

plus first fill is cold but by the time you fill 2nd time its still hot

admit its a long shot but its a cheap part to try

Dave

I see your point and you are right, it is going to be something a little left-field that is causing the issue.

Just starting an experiment where I have let the programme run to within a couple of minutes of where the fault gets reported and have opend the door. I plan to leave it a couple of hours to cool, then shut the door and see what happens.

Accademic, I know, but easy to do, so I thought I would give it a try.

Dave

Nope, not been mentioned, but wouldn’t a problem with that be triggering issues on all other programmes and not just at 2 hours and 1 minute remaining on the Eco cycle?

I’m out of theories and I imagine the service engineers will be too now, when I report back.

Obviously I cleared all the filters as suggested, and I also removed the appliance pipe and checked the in-line filter and all was good. As the appliance was connected to the house mains supply by another 2 metre hose. I removed the inline filter from this, in case it was causing an unnecessary flow reduction. Problem did not resolve.

I reported the fault to AEG and they dispatched an engineer. He said that “there is no difference between the fill that that is reporting the error to any other fill in the programme” and suggested that the fault lay in the extension pipe restricting the water flow and that it needed to be shorter. I said “if there is no difference in this fill to any other then why is it consistently the only time that the machine throws an error?”. He just went back to saying it is a problem with the extension pipe.

So I spent the next weekend fettling and modifying my kitchen until I could connect the appliance pipe directly to the house plumbing. No change; i11 still thrown halfway through the Eco cycle.

The next engineer turns up and apologises for the pipe suggestion, saying it is obviously a control unit problem. Now I’m liking this, as I have though from the off that this is some sort of firmware bug.

Cutting to the chase, the dishwasher has now had both front and rear control units replaced and, you guessed it, it still behaves exactly the same.

Anyone here seen anything like this, or have any suggestions as to what may be the cause? Obviously an engineer will be returning once again, but it would be good to give him/her a steer if someone here has the solution, or a very likely reason for this most strange of faults.

Cheers.

That is very useful thank you.

Do you have any theory as to why this only happens at a certain point in the middle of only one programme – the ECO cycle? Is there any maintenance function that allows one to time/test the flow rate, do you know?

Cheers

Thank you for the reference to the repair kit. Seem like my synopsis if the failure was right – “What I imagine has happened is that grey plastic beam has distorted over the years and pulled away from whatever seal is behind it.” – as the kit seems to comprise a length of rubber that is jambed behind the bowed plastic beam and a rigid metal bar to force the bowed plastic beam back into to contact with the seal.

In a way it is good to know that this is such a common fault that a kit for similar models exists and that I now have a pattern to follow should I wish to take a similar route. Incidently, I had been considering making a similar rigid support to force the warmed plastic back into shape, but on my model it is not immediately apparent where I could anchor it at the ends. Good to know that the “official” fix is the same solution though. This has all been very helpful.

I think I may resort to the silicone sealant through.

As a final question, I notice the kit also includes a new lower spry arm that I don’t see a reason for? What part does that play in this leak do you know?

[VickieS]

Thank you for taking the time to reply. The full model number is: SMV53A00GB/14

I can feel like “fill the gap with silicone sealant” solution becoming my solution.
