How to Fix / Troubleshooting

Safety first: Immediately disconnect power and close the water tap to prevent further leakage.

  • 1. Pull out appliance: Carefully slide the Constructa dishwasher out of the cabinet and inspect the floor for water trails.
  • 2. Remove side panels: With power off, remove side panels to inspect hoses, the sump, and pump area while running a short fill (monitor closely).
  • 3. Identify leak source: Look for drips from hose joints, the sump seal, or the circulation pump. Tighten clamps or replace hoses as needed.
  • 4. Check base pan: If water collects in the base, it may trigger AquaStop errors (E01/E15). Dry the base thoroughly after repairs.

When to call a technician: Cracked tubs or leaking pump seals generally require professional replacement.
