Possible Causes
Loose hose clamp on circulation or drain pump, Cracked plastic sump, Perished pump seal, Split internal hose to spray arms or water matrix
How to Fix / Troubleshooting
Safety: Disconnect power and turn off water. Pull the dishwasher out and place towels around it.
Locate leak source:
- Remove lower front and side panels to view the base.
- Run a short fill/wash while observing (only if competent to work near live parts).
- Identify the exact point of dripping: sump edge, pump body, hose joint, or valve.
Fixes:
- Tighten or replace hose clamps on leaking joints.
- Replace any split hoses with the correct Indesit part.
- If the sump or pump seal is cracked or leaking, replace the sump assembly or pump as required.
Dry the base tray thoroughly before reassembly to avoid triggering the anti‑flood system.
