AW23 fault

[bagman]

This calll is miles away from me, so I’m trying to gather as much info (and possibly pre-order any parts) before I visit the machine.

Customer is reporting ‘E03’ and ‘E54’ error codes.

I can’t find reference to an 03 anywhere, so any clues? As for 54, all I find is:

E54 Autotest's errors Displayed as error code, wasching machine start

inoperable

- programmer damaged ;
- damaged circuit NTC.

So, from that last one it looks like a possible NTC and/or PCB?

Also, as this will be my first UG repair, any procedural help would be appreciated as well.

Thanks in advance

Re: AW23 fault

Before you visit, get them to hold the start button for 20 to 30 seconds.
Then switch off machine then back on.

This can clear the fault. Which is normally caused by people pressing the start button too quickly or too many times in quick succession.

Full Amica codes HERE

Can’t see E03. 😕

All you need to know about E54 is HERE 😉

Exdcellent!

Thanks guys, 🙂

Re: AW23 fault

Back again 🙁

She phoned today and said that for the last week she’s been getting an E03 or an E06 error on every single wash. She then puts it back on a rinse/spin and it finishes ok, so whilst it’s a pita, she can still use it.

She’s also asking about refunds/replacements already (Oh Gawd).. so this could be troublesome.

I need to nail this quickly as it’s a relatively new machine. From the sounds of it, it may be a PCB fault (unless anyone knows any different).
She lives miles away from me so I can’t just nip out and have a quick look at it.

Any ideas guys?

Re: AW23 fault

Sounds like a drain problem to me. A partial blockage in the outlet hose under the sink or somewhere in the drain hose. :hmm:

Re: AW23 fault

Yup, Jim is right, sounds like a drain issue.

The PCBs on the AW23, if they go, they really go. There’s none of this reporting an error that isn’t there malarky with them to date, if they pop they go dead and usually that’s a mains issue or a filter that will take them out. Like many, they’ve proved very robust.

But an intermittent fault on a PCB? Almost no chance. Something else is causing it to report an error when the conditions dictate that it should.

This is a problem with a lot of machines, not just ISE and it’s getting into the right frame of mind that’s the problem…

(If I’m teaching granny to suck eggs please accept my apologies)

The PCB in any machine, washer, fridge… whatever, is just a simple board with, usually one CPU on it and a bunch of relays and resistors along with a mains tranny and a few transistors. They’re basically incredibly simple and reliable as they tend to use a non-volatile chip. Effectively it’s a PCB that switches stuff on and off at the right times but that relies, instead of time like timers in days of yore, on reports from all the components.

What this means is that if they go it’s first off the tranny that will blow, that gives the old “no power, dead” fault when your meter says it should have juice.

Burnt out components can happen, but that’s easy enough to spot, just look for the magic smoke escaping that makes it work. Some really smart electronics whizz kid once told me that all electronics run on magic smoke and that, when the magic smoke escapes, it stops working. 😉

Random errors are almost invariably an external cause fooling the logic of the board to report an error for whatever reason.

Think on it this way…

We all are pretty used to slagging off people for assuming that there was a timer fault when the machine stopped at a certain point on a program on old electro-mechanical timer machines, yes? Same thing, new era and new technology. If the board reports a fault it will almost inevitably be detecting one and reporting that fact, it’s not a fault on the board, it’s a fault somewhere else making the board tell you there’s an issue. That’s the whole point of fault codes, even when they’re not listed, something caused the logic to report it, the CPU picked it up and is telling you there’s an issue which is exactly what it’s supposed to do.

The E03 thing intrigues me though, I will ask factory if they can shed any light.

I would expect one of two things…

1. Suds lock, just like the F3 thing on the ISE10, it’s not a failure and the mountain of suds in the machine doesn’t give the customer a clue that it might, just possibly, be them being stupid with the detergent.

2. It’s something blocking or restricting the drain outlet or hose.

I’d doubt it was an actual pukka, proper real fault in all honesty.

Re: AW23 fault

This machine drains into a standard waste pipe, so there shouldn’t really be any problems there.

I understand what Ken is saying though, and I’m of the same frame of mind. I just wanted someone with experience of the appliance to tell me if there were (or were not) any known issues with the PCB’s.

Looks like I’ll have to take a trip out there, knowing my luck I’ll get there to find a load of fridge magnets stuck to the front of the machine (had that on a Zanussi F/fzr once 🙂 ) or something similarly stupid.

Now that I’m sure of how robust the PCB’s are. I’ll spend some travelling and work time sorting this out. It’s just my lack of experience regarding these specific machines that’s making me ask the questions before I dive in.

Thanks all…I’ll report back asap.

Re: AW23 fault

I have only changed one PCB on this model. It went totally dead after four washes, no display, nothing.

Plastic wrapper trapped in filter/pump unit 😕

Re: AW23 fault

Result then! 😀

I often wonder why they don’t check the bl00dy thing first before going off on one.

Mind you… they often tell you they’ve checked it when, we know that they haven’t really. :rolls:

Re: AW23 fault

Like most of them she said she had checked. Ahh well she was very sorry and grateful for the service so it was worth it in the end.

I used it as an opportubity to have a good poke around the machine as well while I was there… why can’t ALL machines be so easily accessible??
