[header] How to diagnose washing machine problems [title] Check where on the washer the leak is coming from. [substeps] The leak will generally come from the discharge hose at the standpipe in the wall. Are there water stains running down the wall? Perhaps, when you turn the machine to drain, water comes out of the standpipe. 
Adjust the drainage hose if you suspect an obstructed flow or stopped up drain. Another common water leak can be a bad hose or loose connection.
