Dishwasher displays error message C3 or AL4


  • Dishwasher displays error message C3 or AL4
Applies to:
  • Integrated dishwasher
  • Freestanding dishwasher

1. Contact an Authorized Service Centre

Error messages C3 or AL4 indicate a leak and / or water collecting at the bottom of the appliance. We recommend requesting a visit by a service engineer.

Turn off the dishwasher's water supply to prevent flooding.

NOTE: Depending on the problem, you may be charged for a service visit by an engineer, even during the warranty period.

Make a note of the reported error code and quote it when you request an engineer. This will not solve your problem, but it will help our engineer identify the cause of the problem.

  • Report error code: CU

Warning: We do not recommend using the product until the problem has been completely fixed. Unplug the product and do not plug it in again until you are certain that it is OK to do so.
