Risk level

Medium

Proceed carefully and stop if the check is unclear.

Urgency

High

Quick answer

E16 means water could not enter through the filling system as expected. Check the visible tap and hose route, then stop if filling remains abnormal or any water appears.

Safety first

Stop and check this first

  • Close the water valve and isolate power from a dry point if water is visible, filling continues or the inlet device is damaged. Never defeat AquaStop.

Safe checks you can perform

  • Confirm the accessible water supply
  • Inspect the hose and AquaStop externally
  • Stop after one model-approved retry

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Measure the complete filling path

What a technician must be able to justify

Technician visit

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Measure the complete filling path

    What they doService should test supply flow, AquaStop, inlet valve, flow meter, water matrix, harness and control for the E-number.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Follow these steps

Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. Confirm the accessible water supply

    No special tools

    Verify the household valve is fully open and that other taps have normal flow without dismantling plumbing.

    Close the water valve and isolate power from a dry point if water is visible, filling continues or the inlet device is damaged. Never defeat AquaStop.

  2. Inspect the hose and AquaStop externally

    No special tools

    Look for kinks, crushing, moisture or damage; do not immerse, open or bypass an AquaStop valve.

    Close the water valve and isolate power from a dry point if water is visible, filling continues or the inlet device is damaged. Never defeat AquaStop.

  3. Stop after one model-approved retry

    No special tools

    Record the code and stop if the tub does not fill normally, filling continues, or moisture appears.

    Close the water valve and isolate power from a dry point if water is visible, filling continues or the inlet device is damaged. Never defeat AquaStop.

What it means

Bosch's official United States dishwasher table associates E16 with a water-flow or filling-system fault. This page is restricted to Bosch dishwashers: the same code on a washer, dryer or another appliance can mean something else, and the exact E-number and manual decide compatibility.
