Sorry for the delay in getting to your question.
Do you still require help with this?
OK, thanks for that.
ED4 indicates a dryer pcb failure.
Unplug the appliance.
Take the top off.
On top of the tub is the dryer assembly.
At the rear of it is the dryer heater connections.
Mark the wiring (label it) so you know where it goes to.
Push the drum down and forward and pull the wires off of the heater connections.
Insulate the wires and tie them back into the wiring loom.
Try the machine on a wash, obviously it won't work as a dryer.
If it's now working as a washing machine, you'll need to try a new element to cure the ED4 fault.
Hope this helps
Let me know how it goes or if you need more help
You have an ED4 error code.
As I've explained this is listed as a dryer board fault.
However, I've found that in most cases it's low insulation on the dryer heater element that causes the problem.
The best thing to do, is work on the code we have.
Once that's cleared we'll soon find out if there are further problems.
As long as you unplug the machine, it's safe.
Follow the instructions I posted and put the top back on before plugging in again.
Let me know how you get on.
Good luck with the test washes.
They should be fine, most times it's the dryer element causes the problem.
Let me know how it goes.
The next step is to begin replacing parts I'm afraid.
As I stated earlier, the service manual lists the code as a faulty dryer board.
Most times, I've found the fault is actually low insulation on the element.
If you have a megger you can check this, if not, you can only replace parts.
Replace the element, reconnect it and try the machine again.
If it still fails it would suggest the pcb (dryer board) may well be the cause and you have one of the few genuinely faulty dryer boards.
Good luck with it.
Your machine will work fine as a washing machine.
It's only when the dryer element is in circuit that the fault will reappear.
I think you'll find Just Answer send you lots of automated emails so no problems on the reminder.
Good luck with the appliance.
Thanks for letting me know how it went.
Glad you got it working again.
Thank you for the payment, it is appreciated.
