Bosch Dishwasher · Code E18 / E3200

Bosch Dishwasher E18 code: Not enough water

Too little water is coming in, so the water level stays too low. Bosch says the supply should deliver about 10 liters (2.6 gallons) per minute.

Most common causes

  1. Water supply valve under the sink closed or partly closed
  2. Kinked inlet hose
  3. Low household water pressure
  4. Clogged inlet screen or faulty inlet valve

What you can safely check yourself

  1. Make sure the water supply valve under the sink is fully open.
  2. Check the inlet hose for kinks or damage.
  3. Run the kitchen faucet to confirm you have normal water pressure.

Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.
