My name is ***** ***** to hear your having difficulty with your Vac & Steam product.
There are many variances of this product, however I am concerned you are reporting water seeping from the cable entry holes, if your referring to the mains cable please ensure you do not touch it while plugged in as there is a high risk of electric shock.
From what you have described it sounds like the unit has been dropped or banged resulting in the boiler failing, which would give a knocking noise during start up as air is getting into the boiler compartment, you will also see water seeping out as you described.Depending on the age of the unit, you maybe entitled to a reconditioned unit under warranty, can you please advise of the serial and part number found on a label either to the rear of the unit or behind the water tank.
Dear Ellis, do you still require support?
If your happy for the case to be closed, I would appreciate if you could rate the service you have received to date.
