How can I fix my leaking Hotpoint WD440P Washer Dryer?

My Hotpoint WD440P has developed a leak from the door and dispenser drawer and I have cleaned everything out as stated in the manual but it still does it. This has been happening since about two weeks after the drying cycle tipped out our electrics in the house (the dryer has not worked since but I can manage without this). Plus it has also now started not emptying fully after a small fast wash and the manual states that you should clean out the pump filter but i can't find where this is located.
