What Does Error E1 Mean?

The E1 error code on your Blanco dishwasher indicates a water supply issue, often due to insufficient water intake or low water pressure. This can prevent the dishwasher from filling properly and may lead to unusual humming sounds. Common culprits include a blocked water inlet valve, restricted hoses, or a faulty inlet valve. Ensuring a steady water supply and checking for blockages can help resolve this problem.

Common Symptoms:

  • Dishwasher fails to fill with water or shows ‘no water’ condition
  • Dishwasher stops cycle early with E1 displayed
  • Water inlet valve or hose appears affected (e.g., blocked, kinked, low pressure)

Possible Causes

  • Insufficient water supply (low pressure or no fill) (medium)
  • Blocked or restricted water inlet (hose or filter) (medium)
  • Faulty inlet valve (low)
