Having owned the fridge/freezer for 6 years we have problems with water seeping from under the appliance.
We where told that a drain hole in the freezer section was blocked and causing ice to form and then melting.
Having de-iced the drain hole in the freezer by taking the back off in the freezer compartment it seemed to have cured the problem only for it to happen again a few days latter, this the second time this has happened in the last 6 months.

Also check that the pipes go into the trough on the top of the compressor.
