AEG Lavamat Turbo L16830 – Which PCB?

[kiwiroy]

I have a sick AEG L16830 washer dryer and I hope someone can help me get the dress back on her…

Symptoms:
– Washing cycles (40 deg C etc) don’t get very far.
– Inaccurate timer, counts down erractically.
– Diagnosis error code E5E, further E5D after the ELE message.

Diagnosis based on E5E and E5D codes suggest a broken main board, inverter board or wiring connecting the two.

Tested the continuity of the wiring and all good with no shorts, so assumption is that it is one or both of the boards.

Neither board has any burnt areas or visibly ‘blown’ components.

No water leakage issues.

As far as I can tell no earth leakage as suggested here that might have/be corrupting the board.

Is there a way to find which board needs replacement, or if the error code is just a red herring. I mean how does a broken board know it’s broken not the other on, or some other component 😕

Other info (main board):
AKO: 707016-06
Elux: 13226243
SW: W3F30130

Thanx

Element shorts to earth are the most common problem on these w’dryers.
What tests did you do to come to the conclusion that there was no earth leakage? Was a megger or similar used?
Cable loom breakage at connection to motor or inverter board could be causing problem either, seen a few of them with that fault.
:lesson: Careful while working with inverter board as it produces 380v 3phase & holds charge for quite a while, can shock you even if the power is off.

Thanx for the advice and prompt reply…

No I didn’t use a megger, only an ohm meter which claims to do max 1Mohm. Sadly it appears it doesn’t get close in solving this 🙁 Anyway, using the proper kit shows 20Mohm and 1.5Mohm for the drier heating elements and infinite for the main washer element. Does this explain the symptoms seem?

Here’s hoping as 60squids much better than 200.

Yeah an ohm meter normally won’t pick up an earth fault on the drier element, if its reading 1.5Mohm across to earth its likely thats causing the problem. I you take note of the cables position on the heater, take them off, tape them up. Try appliance on wash programme without drier heater in circuit & see does it go through programme without bringing up error codes.

Just updating. After a little coaxing, resetting the error code and power cycle, this machine has done two 40degree wash cycles without the drier element. New element on order. Is there a recommendation to replace the gasket for the drier element at the same time? Condition wise it appears fine.

Thanx
