Unfortunately EC8 would indicate the control board is faulty.
I would suggest unplugging the appliance for 10 minutes then plugging it back in again. See if this resets the main board.
If that doesn't work, unplug the appliance and take the top off.
Unplug each plug from the main board and the facia board then plug it back on again. Do each plug twice to ensure the connection is clean and tight.
Try the machine again.
Tip the appliance rearward about 45 degrees and see if water runs out the base.
If it does, try the machine again and if it works, let me know.
If it still fails I'm afraid you would need to begin replacing the electronics to try and cure the fault.
The service manual states "EC8, CRM (Control module) Pump diode. - Diode on wiring short-circuited".
The pump is directly connected to the control board and the diode is on the board..
If you have to replace the electronics, and if the appliance isn't under warranty, I would suggest getting a fixed price, parts and labour, quote from www.repaircare.co.uk
This would be the most cost effective method of repair.
Hope this is of some help.
Sorry it's not good news.
Let me know how it goes or if you need more help
