eurolec Essentials DW004 - Error Code?

I had the same problem.
This occurred after a drain pipe blockage causing the machine to fail
to drain which then overflowed onto the floor.
In the base of the machine there is a float switch.
If you tilt the machine backwards about 20 degrees this will drain any
water trapped in the base, the float should then reset.
If not open up the right hand panel and free the float mechanism ( a long bit of plastic attached to a polystyrene float)
This should cure your problem.'
