Hi Ian,
Take heart, if it only leaks on the drying cycle, the fault must lie above the waterline! Therefore it is likely to be straightforward – a weeping internal hose or the dryer housing not sealing properly would be the the most likely culprit.
Given the cost of replacement of this appliance with one of similar quality it would definitely be worth getting an engineer to solve your problem!
If you don’t want company service, check the Directories section for your postcode, or post it up here and someone will pick up on it.
