I am trying to find a leak that can not be found with the dishwasher pulled out from under the cabinet. It might be coming from a “supply” line of some sort, but I cant run the unit to see where it comes from. The leak only appears after the unit starts agitating. Any ideas how or where the leak could be coming from? Thanks in advance.
Could be just about anywhere.
As you know water will run along a surface until it finds a low point and then will drip down or spray onto another part and drip from that so finding the actual leak can be a pain.
A small mirror and a flashlight can help you pinpoint it.
You can get a troubleshooting mirror at many auto and hardware/tool stores.
This is a small mirror with a handle, the good ones have an expandable handle with a reach of about a foot or so. Another option is to tape or somehow attach the mirror to a piece of doweling.
