if its the rubber black hose that goes from the soap draw to the top of the tub then you need to pull the hose totally out of the grey tub and put it back in the sealing lip correctly.if the hose has been dragged in to the drum and rubbed away you may need to replace the whole vent hose.using sealant isn't an issue although if correctly fitted and in good condition shouldn't be required
