Professional Repair Guide

What is this symptom?

If your Smeg dishwasher is leaking water, you may notice puddles forming on the floor or around the door seals.

Identifying and addressing the source of the leak promptly can help prevent further damage to your kitchen and ensure your appliance operates efficiently.

Important Tips for Smeg Models

  • Smeg dishwashers can leak at the base due to worn air break O‑ring seals; replacing these seals often resolves such leaks

Possible Causes

Worn or damaged door seal (gasket) allowing water to escape

How to Identify: Water pooling at the front near the door bottom during operation, visible cracks or wear on the gasket

Part: Door gasket (rubber seal)

Damaged or worn O‑ring seals in Smeg air break/flood system

How to Identify: Leak at base inside cabinet, may trigger flood/flood error on some Smeg models; moisture around the air break area upon inspection

Part: O‑ring seals in air break

Loose or damaged water supply or drain hose connections

How to Identify: Leaks visible beneath the machine, especially when running; loose clamps or visible cracks in hoses

Part: Supply hose, drain hose

Clogged or blocked filter leading to overflow and back leakage

How to Identify: Slow drainage, water pooling in the base that then seeps out; debris visible in filter area

Part: Dishwasher filter and drain area

Dishwasher not level causing water to pool at front

How to Identify: Dishwasher tilts forward/backwards when checked with a level tool; leaks occurring mainly at door area

Part: Dishwasher leveling feet

Faulty internal pump seal or inlet valve allowing uncontrolled water flow

How to Identify: Persistent leakage from bottom even when machine idle, water continuing to enter tub

Part: Pump seal or water inlet valve
