Washing Machine Dispenser Light Flashing

[Destamona]

When I start a wash, water goes in the powder dispenser, the light flashes and then it just stays like that. I've cleaned the dispenser and filter. I've tried different settings and its the same. The only setting that works is the spin cycle. And I'm not getting an error message either. Its really frustrating. I've read the manual and there's no advice in there.

 Finally got someone to pull my machine out and this seems to be the problem! Does anyone think this could be a fault with the machine? I have to replace the plug as its melted!
