WME7247S beko motor fault

[petehall347]

i will start at the beginning ..
i was given this machine with error code e11 coming up and no motor action .
i plugged it in and it seemed to be working ok . ran it through the test modes and it passed the tests .
installed the machine and tried a full wash cycle all went well until final spin which it didn’t complete . tried test modes again and i hear the various relays clicking .
removed motor and bench tested continuity which seemed ok so wired it up to bench test and motor spins no problem .
i removed the control board and replaced T1 the triac on the heatsink . tried board back in and still no joy .
i am thinking the AC power is not getting to the control board so will do some continuity tests next .
i could really do with a schematic for the board and wiring diagram for the machine if anyone has these please ?
thanks in advance for any pointers .

well that turned out to be relatively easy .. found a corroded off wire at the motor multi plug . soldered and crimped terminal back on ..was the violet wire ..
its got a load in it for testing ..
hope this helps someone else with the same intermittent problem

well it has just blown the door triac on the front board and 2 resistors . i have triacs but no resistors .they are on order . i suspect the switch blew the triac so i already replaced the switch .

I admire your determination. Thanks for the up date after the 1st time you fixed your machine back in June last year. Let us know the outcome of this lastest disaster.

good news .
resistors came in today and a brand new 1mm iron tip that makes it much easier than using the 2.3mm tip being as the resistors are 0805 smd devices .
anyway just done a full on wash approx 2.5 hrs at 80 degrees .
finished program no problem . nice clean laundry .
seems to have spun better this time .may have been the trolley token at fault i found in the pump filter ..

Re: WME7247S beko motor fault

have not used the machine for a while now . put washing in earlier then found it had e09 fault .suspected door triac yet again . stripped the board out and sure enough the triac was blown apart . fitted new triac and its now working again .
there must be a strange fault with this machine to be blowing triacs when not in use .

Re: WME7247S beko motor fault

bloody thing has broken again .. different fault though . fills with water ok but drain pump is running continuous . fault is e08 . water not filling up .well it cant fill up with pump running .
must be a problem on the pcb . maybe pump triac is switching on when it should be off ? i dunno . i know the triacs arent testing shorted so i will have to dig deeper .

Re: WME7247S beko motor fault

fault can also be pump triac short circuit

Re: WME7247S beko motor fault

problem solved .
traced and changed drain pump triac .. its now washing normally .. hope it stays that way for a while . this thing seems to like eating triacs for some reason .

Re: WME7247S beko motor fault

it smoked today but nothing obvious on the pcb.s . no shorted triacs . nothing looks burned but it smells of burning .maybe from previous burning triacs
fills with water as soon as door is closed .
fault code e10 comes up so might be door switch faulty .
