Does this only happen on the initial fill? Or does it happen rinse cycles too? Where is the leak coming from?
Sometimes, the rubber seals on the water inlet hoses don’t work well or the hoses aren’t tight/snug.
The fill cycle pulls water from the inlet hoses and sometimes (due to water pressure), the jolt caused by this can cause hoses to loosen over time.
My first recommendation is to check the inlet hoses, and verify that they are tight and still serviceable. After that, start a cycle (on hot and cold temp so both hoses pull water) and check for leaks. The leak persists, allow it to run and search for the source.
However, the hoses are often times the culprit.
Hope this helps.
