Dishwasher Leak and Overflow Codes: Safe First Checks

Dishwasher leak codes can be urgent because water and electricity share the same appliance area. The first goal is to stop active water movement and document the condition.

Leak risk

Control water risk first

Leak warnings should be treated as water-risk checks. Stop restart attempts until visible water and the door or hose area are reviewed.

At-a-glance diagnosis

Likely meaning

If water is escaping the appliance, cancel the cycle and shut off the water supply if you can reach the valve safely. Do not reach into standing water around live electrical connections.

First safe check

Check the door seal area, oversized dishes blocking spray, loose drain hose, sink connection, disposal knockout plug, and filter seating. These observations do not require opening the dishwasher cabinet.

Stop point

If water is escaping the appliance, cancel the cycle and shut off the water supply if you can reach the valve safely. Do not reach into standing water around live electrical connections.

Visual check order

  1. 1

    Look around the door lower edge and toe-kick area.

  2. 2

    Confirm the filter is seated.

  3. 3

    Check the sink or disposal connection for backup.

  4. 4

    Watch whether the code appears during fill, wash, or drain.

Stop active leakage first

If water is escaping the appliance, cancel the cycle and shut off the water supply if you can reach the valve safely. Do not reach into standing water around live electrical connections.

A leak sensor code can remain after water reaches the base pan. Resetting repeatedly without finding the source can make diagnosis worse.

Visible checks before service

Check the door seal area, oversized dishes blocking spray, loose drain hose, sink connection, disposal knockout plug, and filter seating. These observations do not require opening the dishwasher cabinet.

If the floor is wet under cabinets or the code returns when the tub is empty, move from homeowner checks to service.

  • Look around the door lower edge and toe-kick area.
  • Confirm the filter is seated.
  • Check the sink or disposal connection for backup.
  • Watch whether the code appears during fill, wash, or drain.

Examples by brand

Samsung LC, LG AE, and Bosch E15 are common leak-related searches. They are not identical internally, but they share the same public safety posture: stop water, inspect visible conditions, then confirm model-specific steps.

Model numbers affected

Commonly searched model families include built-in dishwashers, front-control dishwashers, top-control dishwashers, and compact dishwashers.

This is not a confirmed model-number list. Match the exact code to the full model number on the appliance tag before ordering parts, opening panels, or booking service.
