ctd00p hotpoint condenser tumble dryer?

Is the water coming from the rear, or front of the dryer?
At the rear there's a hose that links the condenser unit pump at the bottom rear of the dryer to the water container. This hose is removable to allow connection to a drain, so check this is not loose or disconnected by accident.
If it's coming from the front, either the heat exchanger is not properly closed or has a split seal, or the seal where the hose connects to the water container may be split or missing.
