Viking FDB451 Designer Dishwasher Repair

Most common issues on this model

  1. LED1/LED2 patterns pointing to a drain, inlet or sensor problem
  2. Filters packed with food debris
  3. Control panel locking up with age
  4. Slow drain or standing water

The FDB451 is a retired Designer 451 Series 24-inch undercounter dishwasher that needs a custom panel and handle. It offers multiple wash cycles and reports problems through a pair of LED1 and LED2 diagnostic indicators.

Those two lights are useful. Different combinations of on, off and flashing point to different areas, such as the drain, the water supply or a sensor, so we begin by reading the pattern and then confirm it with tests. Many older machines also have clogged filters and a control panel that has started to lock up. We clean the filter set, check that the drain path is clear, and then look at the controls.

The written price comes before any part is ordered, and our work comes with a 30-day warranty.

FDB451FDB451 questions
What do the LED1 and LED2 lights on the FDB451 mean?

They flash or light in combinations that point toward the drain, inlet, sensor or control. Tell us the pattern you see, and we use it as a starting point before testing the actual parts.

Is it worth repairing an older Designer dishwasher?

Often yes, particularly when the tub and rack are in good shape. A pump, sensor or control repair costs less than rebuilding the cabinet opening. We give you the price first.

Why does the panel stop responding?

Age, moisture or wear on the keypad can interrupt it. We test the keypad and board, and we confirm the door panel is not pressing on the controls.
