What E6103 Means
The owner manual names one cause for this number that catches out almost every new installation: a food waste disposer whose dishwasher inlet knock-out plug was never punched through. The drain hose is connected, but the water has nowhere to go. A kinked drain hose produces the same result.
Common Causes of E6103
- A disposer inlet knock-out plug still in place after installation
- A drain hose kinked behind the machine or crushed against the cabinet
- A disposer chamber packed with waste and blocking the dishwasher inlet
🔧 One Safe Check You Can Try
If the drain hose runs to a disposer, confirm the knock-out plug was removed when the machine was fitted — on a brand-new or recently replaced disposer that is the first thing to check. Otherwise trace the drain hose for a kink or a sharp bend.
⚠ Why You Shouldn't Go Further Than That
- Knocking the plug out of a fitted disposer means working under the sink with the disposer isolated at the switch or breaker first.
- If the drain path is genuinely clear and the code stays, the drain pump itself is the next thing to measure.
