Fix it guide

Why is my dishwasher not draining?

Standing water means the drain path is blocked or the pump has failed. On integrated European units this shows as a code, F24 on Miele or E24 on Bosch being the common ones. If the filter is clean and the code returns, the pump or the check valve needs replacing.

Check these first

Four things to try before you book

None of these require tools or take more than a few minutes. If one of them fixes it, you have saved a service call.

  1. Remove and rinse the filter in the bottom of the tub.
  2. Check the air gap at the sink if one is fitted and clear it.
  3. Run the disposal if the drain line connects to it, and confirm the knockout plug was removed on a new disposal.
  4. Look for a kink in the drain hose under the sink.

Still not working

When to call

If the fault persists or returns within a day, a component has failed and needs to be tested and replaced. Send the model and serial number from the data plate, the exact symptom and any code on the display. Tradewerx serves western North Carolina, eastern Tennessee, upstate South Carolina and southern Virginia.
