What E6103 means

A cause that surprises many fresh installations: the garbage disposer has a plug on its dishwasher inlet that must be knocked out, and if nobody did it, the connected drain hose leads nowhere. A kinked hose gives the same result. The dishwasher cannot empty, so it stops and shows E6103. The machine therefore stops and displays the number, even though the pump itself may be perfectly healthy.

Usual causes of E6103

  • A knock-out plug left in the disposer inlet after the dishwasher was fitted
  • A drain hose bent behind the machine or flattened against the cabinet
  • A disposer chamber stuffed with waste, blocking the dishwasher connection
✓ A safe check worth trying

1. Switch the dishwasher off. 2. When its drain hose goes to a disposer, check whether the knock-out plug was removed at installation; with a brand-new or recently swapped disposer, start here. 3. Turn the disposer off at its switch or breaker before reaching in. 4. If there is no disposer, follow the hose looking for a kink.

! Why you should stop here
  • Punching out the plug on an installed disposer means working beneath the sink with the unit isolated at its switch or breaker.
  • Should the drain path prove clear while the code persists, the drain pump itself is what we would test next.
Taking off a panel yourself does not by default void a manufacturer warranty, yet it can lead to accidental damage, and some manufacturers attach their own service terms. Read your warranty paperwork, or ask us, before you decide.

E6103E6103 questions
A brand-new dishwasher has never drained. Where should I look first?

At the disposer. A plug nobody punched out is the most frequent reason a freshly installed machine never empties. We can usually tell on arrival which path to follow.

Would running the disposer help?

It empties the chamber, which is worthwhile, but it cannot remove a plug that is still sitting in the inlet. Keep the door closed until we arrive.

Is the plug something you take care of?

Yes. We isolate the disposer, remove the plug and test the drain. It is the first thing we check on a machine that has never emptied.
