unit is leaking from the back air hose only during cleaning cycle ,any suggestions please help

Hi. Which hose is it leaking from? Here is a link for the parts diagram. http://lookup.appliancevideo.com/lookup/213694/1452152 Are you referring to number 5 on diagram? The ventilation hose? I do believe the clean washer cycle does fill up with more water than a wash cycle, but it still should not be leaking out. Is there too many suds in the unit ? Does this hose have a crack or a bad seal? Le me know. Thanks.
