right I have to assume that you have checked that the pump is workink so nex you have to check that the pipes are clear of foreign objects like 5p's or buttons which can get into the waste pipe and block it, have you tried blowing down the waste pipe? if there is a large blockage it will be obvious with that test when you have checked the waste pipe (both ends) then check the sump hose that runs from the tub to the pump and also check for anything in the pump
