Dishwasher Leak Emergency Guide

Dishwasher Leak Emergency Guide

Stay Calm. Stop the Leak.

A leaking dishwasher can quickly damage kitchen units, flooring and nearby rooms if left unchecked.

This guide explains the steps to stop the leak, reduce water damage and protect your home safely.


Step-by-Step Guide

Step 1 – Turn Off the Dishwasher

Switch off the dishwasher and stop the current wash cycle if it is still running.

Do not continue using the appliance until the cause of the leak has been identified.

Step 2 – Turn Off the Water Supply

If possible, close the dishwasher's isolation valve.

If you cannot stop the leak at the appliance, turn off your home's main stopcock.

Step 3 – Contain the Water

Use towels, buckets or FloodFort flood bags to help prevent water spreading across the kitchen floor.

Position the flood bags around the affected area to help contain the leak and protect nearby rooms.

Step 4 – Check for the Cause

Inspect around the dishwasher door, hose connections and underneath the appliance for obvious signs of leaking.

Do not pull the dishwasher out if it is unsafe to do so.

Step 5 – Dry the Area

Remove standing water and dry the floor thoroughly.

Allow the area to dry completely before using the dishwasher again after repairs have been made.


FloodFort Tip

Keep your FloodFort Kit somewhere easy to access so you can respond quickly to unexpected water emergencies.

Having your FloodFort flood bags ready before an emergency happens can help reduce water damage while you investigate the leak.
