Here is an update on my current findings:

I got some inputs from a technician. He told me that after entering the test-mode (by holding two buttons and turn the knob one step clockwise), I should release the buttons and turn the knob: one step counterclock-> one step clockwise -> one step counterclock. This should apparantly make the machine exit the test mode.

Unfortunately, this did no difference at all

Currently I have two theoris:

1) I have wrong software on my board. I am currenlty trying to verify this.
2) The communication between the u-controller on the button/display board and the main board is broken. The test-mode that we both have entered could be a test-mode of the button/display board itself. Buying another buton/display card is not very tempting taking into account that it could be something complety else wrong.

Note that I found a service manual for the EWM 100 plus board used in an electrolux machine. I'll dig up the link again. It could be of some value.

Hi Tanami,

I'll keep you updated. I can however give you some more information right away.

When I ordered my new main board, the repair guy first said that the board had to be programmed in order to work. However, after checking with a colleague, he told me that the main board was shipped pre-programmed. Along with the mainboard, a notice explaining that some IR-interface connector (3-wires) should be left unconnected. I think this IR-connector leads to an IR-diode in the front, being used as an interface with the programming tool. This support the information I got that no programming should be required. It was also said that I had to turn on and the off again to exit a test mode, which I did without any effect

I'll try to call the repair guy tomorrow. Hopefully he is willing to give me a tip or two, taking into account that I bought the main board from him for appr ˆ250.

Hello olealexa,

Unfortunatly I failed to repair my machine, altough I am quite sure it is related to some hidden setup/procedure and/or wrong ROM code within my new main board. Finally, after two months without a washing machine (family with three childs and a baby) I bought a new machine.

Still,
I'll appriciate if you will keep me updated in case you have any solution as I am keeping the problematic machine.

Regards,
Tanami

Hello Tanami.

Did you find out of your test mode trouble? It seems like I have run in to exactly the same problem as you did after replacing the main board. My L74560 seems completely dead until I do the combination of pressing two buttons and turn the knob. Then it enters some test mode similar to what you describe. I would really appreciate if you could help me out of this trouble.

Hello,

I know how to deal with electronics (both HW and SW) but this is not of help as, most likely, I need some hidden codes for being able to configure my machine.

Background:
I am located in Israel but my machine was purchased in the UK. Unfortunalty this specific model (PNC) is not supported in Israel that;s why I failed to locate any local profetional that can support me.

Recently I replaced the main board (configured board EWM100+) as the original one was burned out. Unfortunatly it is not functional altough it was electrobicly installed.

I suceeded to enter electronic test mode by pressing two hidden buttons for ~5 secs while turning the machine on. In this mode you can see all the leds, each button press results in desplaying it's ID on 7-seg. Each main selector change results in it's program code on the 7-seg.

I understand that there is some priocedure to configure the new board to my machine. This is what I am looking for .. I assume it is explaned as part of the service manual ?

Any advice will be much appriciated.

Thanks,
Tanami


you don`t need service manual for this...you need to know a little electronic ...to check some parts
