Leak Detected Dishwasher Codes: What to Do First

A leak-detected code is not just an inconvenience. It means the appliance or sensor system believes water may be where it should not be.

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

Cancel the cycle. If water is actively escaping and the shutoff valve is reachable without standing in water, shut off the supply.

First safe check

Check the door seal, oversized items blocking spray arms, filter seating, detergent amount, drain backup, and loose hose connections under the sink.

Stop point

Cancel the cycle. If water is actively escaping and the shutoff valve is reachable without standing in water, shut off the supply.

Visual check order

  1. 1

    Inspect the lower door edge.

  2. 2

    Confirm the spray arms can turn.

  3. 3

    Check sink or disposal backup.

  4. 4

    Look for foam or wrong detergent.

Stop water movement

Cancel the cycle. If water is actively escaping and the shutoff valve is reachable without standing in water, shut off the supply.

Do not keep starting the dishwasher to see whether the code clears. A base-pan sensor may stay active until water is removed and the source is fixed.

Look for visible causes

Check the door seal, oversized items blocking spray arms, filter seating, detergent amount, drain backup, and loose hose connections under the sink.

Over-sudsing can look like a leak. Use only dishwasher detergent, not dish soap.

  • Inspect the lower door edge.
  • Confirm the spray arms can turn.
  • Check sink or disposal backup.
  • Look for foam or wrong detergent.

Common brand patterns

Bosch E15, LG AE, and Samsung LC are common leak-related searches, but each model handles detection differently. The public advice should stay conservative.

If the code returns after visible checks, service is usually safer than cabinet removal.

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.
