E3 CODE WHAT MEANS

Daewoo e8 - engine error! or Bad soldering.
Remove the control panel (the one in which many connections). Remove the rear rubber compound around contacts blue relay.
Resolder them. And it will be all ok!
Or - remove the entire back of the compound and look for where the bad soldering (cold soldering ). You can see it - blackened or exfoliated. Just solder all.

It could be the pressure sensor. If if never detects that there is enough water then it will never do anything else. The pressure sensor has an air small air hose that goes to a hollow, usually plastic cylinder that measures the pressure. Make sure the hose is securely attached on both ends. By the way, there should be a wiring diagram in the bottom of the unit for "service" point of view, but if you can follow a simple print you can read this. One end of the hose goes to a small electronic...sort of module...it has a cylinoid that will allow 115VAC to pass through or not. Generally, if it is not passing 115vac then it does not thing there is enough water in the drum yet. If you have a multimeter you could check the wires for 115 with the drum empty and full. If the 115 goes on and off then it gets worse because it is the main board. Hope that helps.

The E8 error code has a simple fix.. change the carbon brushes, I had the problem and I do every 12 months or so, I make brushes at work (Mersen) and was able to manufacture some from grade Eg300 H, and get 2 spare, they cost around ZAR 150.00 around 10 USD.two screw to take the brush holder off the motor(tilt the machine on its side, against the wall) and work from the bottom of the machine.
