More on AEG Lavamat 74335 PNC 91400220602 – the story goes on……
This one is driving me nuts!
I ran the diagnostic programme for the EMW2000 control unit.. But although this machine has the EWM2000 board, it has no fault code display LCD, instead displays a code on the eight vertical wash-progress display LEDs. and this is not covered in any literature I have. On the 8 LEDs I get a code of LEDs 3,4,6 (from the top) all flashing after step 6 of the diag. This is I guess the actual fault code. Can anyone help me out here with what this means?
I have changed the interlock. All functions seem to work OK on the diags except spin (diag step 9) although step 8 (spin up to 250rpm) works OK. The machine fills (all valves), empties, heats, agitates, spins up to 250. It will not complete the step 9 (pumpout and spin) – it will only pumpout, no spin. I’ve done all the resistance tests on the motor and these are fine.Brushes/commo are fine. Also metered the heater. I’ve meggered everything appropriate. I took out the PCB and checked for burns etc.. Blown thro the pressostat lines. Looked over the loom. Prayed to God and Allah….
(It doesn’t help that the bloody machine is in the downstairs toilet with no room to swing a cat.)
Can anyone send me info on this fault code, or email me some stuff for this Lavamat?
Cheers

From what i can gather, that would be E34.

Have you TDS off line? the fault codes are on there.
Re: Fault Codes on AEG Lavamat 74335
Last known error code is displayed at the second last selector position before the off position if you are turning it clockwise. (normally a spin position). If you split the 8 lights into the top four and the bottom four, then the top four are the first digit of your fault code and the second four are the second digit. Taking the top four then count the bottom one as 1, the second one up as 2, the third one up as 4 and the top one as 8. So if the bottom two are lit then that is 1+2 = 3. So the first digit of your fault code is 3. Do the same with the bottom four lights and if the third one up is lit then it is 4. Therefore your error code is 34. Hope that makes sense 🙄
Re: Fault Codes on AEG Lavamat 74335
well 2 of us both came up with E34 so I guess we must be doing something right!
get yourself the TDS disc p/n 5 0600 60 65-00/3 only £20 and its all on there.I’ve got the Diagnostics Guide to the EWM2000 board. E34 would make sense re the diagnostics program but not the original fault.
Original fault is: the machine aborts every program after only 5 secs (with the pump running OK during this 5 secs)
Per the manual E34 takes 60 secs to register the fact that (and I quote!) –
“There is an incongruity between the water level measured by the analogic pressure switch and the mechanical pressure switch “anti-boil switch 2“ (incongruity for more then 60 sec)” (lovely language! Who writes this stuff! ) Presumably that means the 2 level switches are failing to register the same water level – meaning a split hose, a blocked hose, or a faulty switch. Am I right here?Unless I’m missing something, surely this would not stop the machine from even filling?
Could this just be a board fault?

Mike, I am not 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} on this but I would think the 60 seconds is refering to changes in the level switch’s during a wash cycle when drum agitation would be picked up by the analogic but not the mechanical pressure switch. If the two are giving different readings when the machine is first started then I would assume the module would pick it up as a fault immediately. I have found these boards to be quite reliable, unlike the analogic pressure switch’s which can stick (always worth giving it a light tap on the top to see if the rod has stuck inside). Unfortunately I do not know of a way to test these and it is a case of trying another one in its place. Go for the cheapest part first 🙁
Am I right in saying the analogic pressure switch is the “unusual” looking one with the cross on the top?
Come to that, until now I have never come across one of these – what exactly are they?
(is it pronounced anal-ogic perhaps :-)))
Re: Fault Codes on AEG Lavamat 74335
I have checked all motor components and all readings are OK and nothing down to earth (tested with a Megger)
I’m going with the analogic (induction) pressure switch, I’ve ordered one. and I’ll let you know Friday!! Fingers crossed!
Re: Fault Codes on AEG Lavamat 74335
Just noticed I never wrapped up this topic!
Yes it was the analogic pressure switch.
Another happy ending thanks to you guys and Whitegoods forum!!

Re: Fault Codes on AEG Lavamat 74335
MIke. I had the self same thing a week or so ago. Mine was the analogue pressure switch too.
Just a note for anyone following this topic though. A blocked recycling pump can give this error code on some machines. As soon as the recycling pump cuts in, it puts a negative pressure on one of the pressure hoses and gives a conflicting message to the module.
