bosch washing machine problem

[jclinie]

i have a bosh washing machine -model WAA24171GB
i had a filter hose problem which i sorted but when i connected back upthe machine i turned on a washing cycle and pressed start-no water was coming into the drum-i had forgotten to turn back on the water supply hose- i turned off the power to the machine, turned on the water supply and tried again-but this time no lights appeared on the control panel- i checked the fuse in the plug-it is fine-i took off the top of the machine and checked for power where it enters the machine -its getting power 220volts-i followed the two red cables to the control panel and tested for power -one connection has 220 volts , the other connection nothing- im thinking is the control panel blown or would there be a fuse somewhere hidden on the panel board
any help much appreciated

Are you saying you measured across the 2 reds or from each one to earth? Does the input cable go to a suppressor before it goes to the board?

hi ,thanks for replying
i measured from each red connection to earth seperately
the power supply into the machine brown ,blue, and earth cables wire into a box looking similar to a relay switch ,maybe this is a supressor, and the two red wires come out of this box to the control panel

I think you should have a voltage across the 2 wires, so it would appear that your problem is prior to the board ie. you are loosing a neutral. Is the device you mention this http://www.candmdomesticappliances....ne-mains-terminal-block-and-suppressor-181928 if so then I would check input & out put there.

thanks again for your reply
yes ,thats it as you attached
if i replace that part will it sort out the problem do you think

You need to check that it has 240v going in & out of it first, if not then it would appear to be faulty & causing your problem.

ok-thanks again -i will check that and let you know how i get on

i disconnected the suppressor and brought it to a washing machine parts centre and he told me it was not faulty-so what next- someone suggested it might be a door sensor but how would i get access to this-what do you think?
the guy at the parts centre wasnt very helpful ,he was more interested in gettig me to ring a call out engineer-thats what im trying to avoid unless i have to jc

First of all are you using a multimeter to test the voltages?
Did you get an input (230V) at the suppressor when measuring across the live & neural( ie the mains cable brown/blue)?
Did you get an output across the wires leaving the suppressor?

thanks again for your reply
when i refitted the supressor in the machine ,having done nothing with it
,i powered up the machine just to test it ,having been told it was not faulty- and the lights lit up on the display-dont know why -but the machine is working perfect now-
emergency over
thanks again for all your help

Thanks for the feed back, my suspicion would be that you somehow disturbed the neutral wire when you were doing the hose.
