My daughter has a Hotpoint DC27 Dishwasher which is only 3 months old.
It now refuses to start, flashing the prewash light. We have checked
all the filters and hoses etc. and can find nothing wrong.

We have called the Hotpoint Service people but can't arrange a visit
until about 2 weeks time. Does anyone know what fault this flashing
light indicates? Maybe it is something simple we have overlooked?

Thanks
Jim Orchard
