No display on Beko washing machine WM 741135w. all fuses etc checked, 240 volt supply to rear of main pcb, has the main pcb blown ?

unplug from wall check contacts at motor and pcb/ timer plug back in see if that works motor pulls a lot of juice look for a burnt contacts or connections. motor may be thermally fused .dont just bypass find the reason why thermal fuse failed

Controller fails to detect door lock triac correctly This error code is displayed if the main control unit fails to detect the door lock triac correctly. Also, if the controller cannot unlock the door after 240 seconds after the cycle is completed then this error will be shown.
If displayed switch the washing machine off completely, recommend disconnecting it from the mains supply for a few seconds. Switch it back on and the controller will attempt to unlock the door once more but, if it fails to do so in the same 240 seconds the error code will be displayed once more.

• Check all wiring and connectors between the main controller and the door lock
• Check main control unit, probably requires to be replaced

Bad control board - replace.

Beyond that could just be the door latch itself.

is this a stack washer and dryer . if it is it will be connected to a 240 volt supply and sounds like its only running at 120 volts check main power supply either fuse or breaker is not tied

Seems that the main panel is defective. The fault suggests that the program controller or the processor is malfunctioning specially when it works for some time. If you can check on the +5 volt to the processor , the power supply factor can be established as a faulty supply or a blown mains capacitor can also shown this fault .
So remove the panel and check the components for any visible signs.

Not knowing the model of the mixer you are talking about, or where you are in the world and the voltage you are running at, I can't tell you. But I can tell you how to figure it out. Simply do this:

You obviously know what your main power supply voltage is, either 240 volt or 110 volt
You can look at the mixer and there will be a data sticker with the wattage of the motor on it

Watts divided by volts = Amps

Therefore, if you have a 500 watt mixer on a 240 volt system 500/240 = 2.083 so use a 3 amp fuse
a 750 watt motor on 240 volts 750/240 = 3.12 so use a 5 amp fuse
a 500 watt motor on a 110 volt supply 500/110 = 4.5 so use a 5 amp fuse

etc etc etc.....

Hope this helps

Make sure there's power getting to the washer. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power. Sometimes the power cord disconnects at the washer, if this is the case, the wiring must be repaired or replaced.

hi there.......this problem could be caused by a failed heater element ...if the element is not heating the machine will just wash wash etc...the front panel will have to be removed to check the heater element....if the element is ok...check the heater NTC ( little white plug in the heater element)...if all ok here....then you have a main PCB board failure....

it may be more economic to have beko send an engineer to you...

Check fuses mounted near transformer . If blown check output transistor. Also check transistor transistors on small heat sink . they will cause fuse to blow.
