What 999 means
On models with the Floor Protect with Alert feature, 999 means a possible leak and the dishwasher won't start. On other models it means the control needs to be reset.
Likely causes
- Leak detected by Floor Protect
- Control needs a reset
Safe first checks
- If your model doesn't have Floor Protect, reset the control by switching the dishwasher off at the circuit breaker for a minute or two, then back on.
When to stop
On Floor Protect models, GE says to contact service. Don't keep running a dishwasher that's leaking.
