What F-2 means on your Dacor dishwasher (dacor dishwasher f-2)
Dacor dishwasher f-2 is the EDW/IDW platform’s circulation-pump failure: when the control board commands the wash cycle to begin circulating water, it expects the pump relay on the power board to close, and f-2 fires when no relay closure is ever detected. Without confirmed relay closure, the board has no evidence the pump is actually running, so it halts the cycle rather than continue as though water is circulating when it may not be. This is distinct from a pump that runs but circulates weakly — f-2 is specifically about the relay confirmation never arriving at all.
Symptoms
Use these signs to confirm the dishwasher really has this problem rather than one of the several dishwasher problems that resemble it.
- F-2 appears early in the wash cycle, shortly after the fill has completed.
- No hum or motor sound is heard from the pump area once the cycle should be circulating.
- The tub may fill with water normally, but nothing happens afterward before the problem shows.
- A faint clicking sound from the power board may be audible without any following pump noise.
- The problem can be intermittent, appearing on some cycles and not others, if a relay contact is marginal.
Common causes
Each cause below can produce F-2 on a dishwasher, and only measurement on the dishwasher itself will tell you which one you actually have.
- Failed pump relay on the power board — the relay itself is not closing when commanded, even though the rest of the board functions.
- Circulation pump motor failure — the pump has failed to the point it draws no current the relay can confirm.
- Wiring failure between the power board and the pump — a loose or corroded connector interrupts the relay-closure signal path.
- Seized pump impeller — debris jamming the pump can prevent it from starting even with a healthy relay and motor.
- Power board component failure — a broader problem on the board can affect just the relay circuit for this specific function.
Troubleshooting steps you can try
These checks cost you nothing on a dishwasher and often end the problem there; anything harder on a Dacor dishwasher needs a technician.
- Listen carefully at the start of the wash portion of a cycle for any motor hum from the base of the dishwasher.
- Power-cycle the dishwasher at the breaker and run a short cycle to see whether f-2 appears again at the same point.
- Check that nothing is heard rattling or grinding from the pump area, which could indicate a jammed impeller.
- Note whether the problem happens on every cycle or only some, since intermittent problems point more toward a marginal relay.
- Avoid running repeated cycles back to back while f-2 is occurring, since the pump will not confirm regardless.
Parts a technician may replace
Depending on what the diagnosis shows, a technician may inspect, test, or replace the circulation pump, pump relay, power board, and wiring harness. The right part for your Dacor dishwasher is matched from its model and serial number, and confirming which component failed keeps the dishwasher repair to what it actually needs.
When to call a technician
F-2 needs the power board and pump tested directly, since the relay-confirmation problem can originate at either the board or the pump motor, and only a technician can isolate which. This rates Medium on a dishwasher, so take your time — but do not keep clearing F-2 on the dishwasher without finding out why. Independent service on a Dacor dishwasher means genuine OEM or trusted-supplier parts and a 30-day warranty on our workmanship.
