Try these first

Start here before buying a part or taking the appliance apart.

  1. 1
    Check the inlet hose (documented)

    Bosch’s documented first check: make sure the inlet hose is not kinked or damaged. A pinched hose alone produces E3200.

  2. 2
    Confirm the water supply is on (documented)

    Make sure the supply valve under the sink is fully open — a partially closed valve after plumbing work is a frequent cause.

  3. 3
    Check household flow rate (documented)

    Bosch specifies the water flow rate should be about 10 liters per minute. Open the kitchen tap fully with a jug: if the house supply is weak, the dishwasher is not the problem.

A quick explanation

What does E3200 mean?

Bosch documents free checks first (inlet hose, supply valve, 10 l/min flow rate). The inlet valve is a candidate replacement only after those pass.

The answer you came for

How to fix Bosch dishwasher error E3200

Free checks first — most E3200 cases end at the hose or the valve handle, not at a part order. The inlet valve is a candidate only if every documented check passes.

  1. 1

    Run the documented checks

    Straighten/replace a damaged inlet hose, open the supply valve fully, and confirm roughly 10 l/min household flow — exactly the sequence Bosch publishes.

    What you should see: Simple supply-side causes are eliminated in minutes, free.
  2. 2

    Clean the inlet filter screen

    With the water off, unscrew the hose at the dishwasher end and check the small filter screen in the inlet for debris; rinse and refit it.

    What you should see: A clogged screen — a common cause — is fixed without parts.
  3. 3

    Retry a full cycle

    Run a short programme with the panel visible. E3200 that still appears after hose, valve, flow, and screen checks points to the inlet valve or fill system.

    What you should see: You know the remaining suspects are internal.
  4. 4

    Valve replacement only after verification

    If everything external passed, the water inlet valve becomes the likely part. Match it to your exact model (E-Nr plate) before ordering — the candidate below is not a confirmed fit.

    What you should see: Any valve ordered fits the dishwasher exactly.
If the code comes back

Do not keep replacing parts based only on the code. Repeat the safe checks above. If the fault remains, stop and arrange qualified service rather than ordering from the code alone.

What may be causing it?

  • Kinked or damaged inlet hose
  • Water supply turned off or partially closed
  • Insufficient household flow rate
  • Clogged inlet filter screen or faulty water inlet valve

These are possibilities to investigate, not proof that one part has failed.
