OK, thanks for that.
The container light is controlled by a float switch
at the pump reservoir.
This is the likely fault, a blocked pump and/or reservoir.
Unplug the appliance.
Take the top and side panels off. (some need a screw removed on the front, some have a hidden screw underneath the side panel).
Follow the drain hose back and you'll come to the pump.
Take the pump out, clean it out, clean out the reservoir.
Reassemble it all and try again.
If the pump, wiring and control are all ok, it should be working again.
If still the same, you need to check the pump is ok first.
Hope this helps
Let me know how it goes or if you need more help
