It sounds like your unit may be in flood mode. Give me just a moment to pull up your manual and see how we can fix this for you.

  • In the picture below the drain pump is #410, the switch is #407 and the styrofoam float is #415.

To gain access to this you will need to remove the unit from the cabinets.

Hello Webb Guy, Week ago Charcoal filter mistakenly placed in DW exploded, leaving tiny granules through out. Turning on DW got strange buzzing noise and lights that changed to pots after a few sec of operation. I found diverter valve making noise, and upon disassembly found unit jammed with pellets gears stripped. Ordered & installed new part form Viking. Noise gone. Drain pump runs all the time no lights. Checked flood mode/switch, not the issue. Took door apart to see if controls damaged, found circuit board will light when removed. but will not program. Drain pump runs all the time. Interesting circuit board.. The rinse mode module can not be near anything hand, plastic etc as it prevents any lights to come on.

So then the issue sounds like its with your circuit board then and that will need to be replaced.
