Sub-Zero & Wolf Error Code E1
Water leak detected
Common Causes
- 1Door seal failure
- 2Hose connection leak
- 3Tub crack
Disconnect power before inspecting for leaks. Water near electrical components creates shock hazard. Check for water damage to adjacent cabinetry.
Step-by-Step Troubleshooting
- 1
Check the float switch in the base pan — Cove dishwashers use a flood sensor that triggers E1 when water reaches the base
- 2
Inspect the door gasket for tears, food debris, or misalignment — the Cove door seal is precision-fitted
- 3
Examine all hose clamps on the drain and supply connections under the unit
- 4
Look for cracks in the stainless steel tub — rare in Cove units but possible from impact damage
Pro Diagnostic Tip
Tilt the Cove dishwasher back slightly and inspect the base pan. If water is present, dry it completely, run a cycle, and watch to identify the exact leak source.
