Why a dishwasher reports a leak or anti-flood protection
An anti-flood code is not a cosmetic fault. The first job is to stop use and confirm where the water is coming from.

Symptom summary
Water in the base tray or a triggered float switch means the dishwasher has already detected a leak risk.
Likely causes
- A visible leak from a hose or seal.
- Over-foaming sending liquid into the base tray.
- An internal leak that returns on each run.
Safe DIY checks
- Switch the appliance off, disconnect power, and shut off water.
- Look for a visible leak path around the door, hoses, and siphon.
- Do not keep forcing restarts until the water source is known.
When to stop
- Stop immediately if there is an active leak under the dishwasher.
- Stop if you notice a burning smell or the breaker trips.
