OK when you get back home, please try this and let me know how it goes:
You will have to unplug the appliance and remove the bottom front flap.
Then keep some beach towels and shallow container under the filter.
Now, rotate the drain pump filter anti clockwise to open, clean it completely and make sure it is not clogged.
Also with your fingers check if impellor rotates, then reconnect everything and plug it back.
Try a empty wash program on its hottest setting, if control comes on.
However, if it still has no power then I am afraid the power board is faulty and will need replacement.
The cost of repair will be around £155 + repair charges.
I hope this helps, please do not hesitate to ask any follow up questions.
