AEG FFB41600ZW dead – cursed

[Gokhk]

Hi All

i swear I’m about to lose my mind , put this machine in place of an e15 error Bosch.

Did one cycle at 70 and threw up some errors , now it’s totally dead !!!

im not sure what to do as I’m sick of these problems now but again any help or hints would help me. I’m hoping it’s not pcb but knowing my luck it is !

Sorry Dave & Andy in advance I know Iv given you enough headaches with the Bosch.

First thing I tried Dave plus plug fuse

When First installed the machine started a 70 degree wash and 40 mins came up with an error according to a flatmate and now is dead , no power what so ever.

Do these have a thermal cut out ? The worry is what caused it to trip as I said I’m petrified it’s PCB as that’s £160

well first i need the full pnc number

looked up the model and got 33 machines with same model

also the board may be faulty but can sometimes be repaired

Ok Dave will get PNC number asap

The mystery depens

So here is the PNC 911 514 013 01

type is GHE621DB4

I went to the flat yesterday removed the fuse and put a new one in , machine powered in to life and started a wash and completed a wash I believe.

Then this morning went to switch on and same issue display dead and nothing.

Not sure what to think as surely if PCB gone it would be dead not intermittent. Heater maybe ? Never had something cause a machine to act dead until fuse removed. Original fuse was fine FYI.

im stumped

have had boards do this

you turn them off and back on and they burst into life

thanks Dave , so question is ,is it definitely the PCB and are these machines built well enough to justify the cost of repair ? I can soon send the board off for review around £50 but I don’t get how it will complete a cycle or start one and then die until you take fuse out ?

one weird thing I noticed is when I took the fuse out and put a new one in , display lit up but then when I swapped it back to Orginal fuse it started filling with water. Now I can’t be sure if it did this the first time but this seemed very odd.

is there any other module , cable etc I should be checking ?

im gonna try a 30 min wash and see what errors if any come up or what it actually does before dying.

Thanks again Dave

every board need a power supply. its normally a small chip (like tny264) that converts mains to 12v or so to power the board. these chips can fail in various ways including being intermittant. you say you changed the fuse and it came back on well the chaces are if you just unplugged and plugged it back in 5 mins later it would do the same
as for the change of fuse and it started to fill well once you start a programme the timer remembers where it is. if the power is interupted and then restored some time later the machine carries on where it left off

Thank you Dave as always your the man , let’s see will have a look for that chip and let you know what I find though it may take a couple of weeks , be glad to get it going if possible

[Gokhk]

Just to update you , all of a sudden its working normally now , it has ran several cycles and been so even more puzzling perhaps something was blocked in filter and the machine gave a error code that needed resetting via unplugging but glad it seems to work now though i will be keeping a close eye on it. Thanks again to dave and everyone for your help
