I have a Samsung WF70F5E0W4W washing machine and after starting a daily wash it stops after few minutes (5-8) and stops, after few starts it gets error 3E. Turning electricity off at the socket for some 30 minutes used to fix this for a while, however now it’s persistent. I took the top cover off, and disconnected all cables to main PCB then connected them again. It worked once, then problem is back. After watching one of you videos I took the motor out and checked both brushes, they are fine – lots of them left. I watched some of your videos and thinking about changing the PCB. Samsung is got them in stock. https://www.samsungspares.co.uk/pcb-assembly-2-pcbs-display-control-in-a-plastic-housing-dc4100203b-dc4100204b/product.pl?pid=4699703 Would you recommend doing some other checks before ordering the PCB?

Hi Gregory, sorry to hear about the problem with your Samsung WF70F5E0W4W Washing Machine,
The first thing I would be checking is the drainage system as E3 error code relates to unable to empty in the allocated period of time. I would recommend you to visit the page below.

You want to make sure that you have a good flow of water coming out of the waste pipe. You can check this by using a bucket if the machine is unable to empty the water in the allocated period of time it will not be allowed to go into spin this protects any damage taking place.
I’ve also added exploded view of your machine along with the useful videos below. In addition to these, you can also find the spare parts at the bottom of this page.
If you need any further assistance please feel free to contact me. all the best Paul.
