Step-by-Step Troubleshooting
- 1
Check water supply valve under the sink — must be fully open
- 2
Inspect the Cove water inlet valve screen for mineral deposits — hard water areas require periodic cleaning
- 3
Measure water supply pressure — Cove dishwashers require minimum 20 PSI for proper fill

Pro Diagnostic Tip
Time how long the unit attempts to fill before triggering E3. If it runs the fill valve for the full timeout period with no water, the supply is blocked. If water enters slowly, low pressure is the cause.
