I’m tried checking the plastic tubes, filter, and drain hole within the dishwasher but no clogs.
The black pipes that go into to ground are not drained since this same is used frequently everyday by my sink with no issues.
I tried scooping the water out. Turning off the breaker to the power for 30 minutes. Holding the start by to reset it.
But it will not drain the water nor do a proper cleaning. And to sanitized light flashing. It seems maybe looking for a product to start sanitize cycle maybe? We tried adding liquid to it, closing it, doing a sanitize cycle, but the same problem.
The thing I learned when I had dishwasher issues was to always start with the manual. You’ll probably be surprised with how much info is in the manual.
The Samsung dishwasher I had issues with had 50+ pages worth of diagnostics and repair instructions, including detailed meanings for every unique error code that can occur, and instructions for putting the whole unit into a test mode, where you can force each motor to run independently, run test routines for sensors, etc. Gave me everything I could want for DIY repairs.
Can’t say it’s always this nice, of course, but this adivce has served me well for other appliances since.
