If the SD code appears during normal operation, it may suggest a more serious issue requiring attention.
Common Symptoms:
- SD code appears on display during diagnostic or relay test mode
- Dishwasher otherwise may not show operational faults associated with this code
Possible Causes
- Error code displayed due to the dishwasher being in relay test or diagnostic mode, specifically indicating the detergent dispenser activation phase. (medium)
How to Fix Error SD
DIY Fix Exit diagnostic mode and clear SD display
- Cancel the current mode by pressing the Cancel/Start button as appropriate for your model.
- If that does not clear the SD code, turn the dishwasher off and disconnect power (unplug or turn off the circuit breaker) for several minutes to reset the control.
- Reconnect power and attempt a normal wash cycle to confirm the SD code does not reappear during regular operation.
Technician Only Verify control panel behavior and dispenser signals
- Enter diagnostic mode using the manufacturer’s procedure to confirm SD appears only as part of the relay test sequence.
- Check the control board and dispenser circuit for correct signaling if SD appears outside diagnostic mode and is associated with operational issues.
Parts needed: Control board, Detergent dispenser assembly
- If SD appears outside diagnostic/relay test mode and dishwasher exhibits additional operational faults (e.g., detergent not dispensing, wash cycle failures)
