Why are my Smeg UG405DSUK washing results poor?
- Q
  qrichardsAug 2, 2025
  Poor washing results from your Smeg Dishwasher can occur due to several reasons: * Clogged or crusted spray arm holes. If this is the case, dismount and clean the spray arms. * A clogged filter. Clean the filters. * Insufficient or improper detergent or rinse aid. Verify the detergent type and quantity. * The detergent or rinse aid cannot be withdrawn from the dedicated containers because of a worn or broken internal tube for detergent or rinse aid of the peristaltic pump. It should be replaced by the After-Sales Service. This ordinary maintenance service is recommended at least once a year for the correct functioning of the dosers.

  Insufficient drying in your Smeg Dishwasher can be caused by: inappropriate rinse aid, or if it is not dispensed correctly. Verify the rinse aid container and if it is adequate to the type of mains water. If the problem persists, contact the After-Sales Service. Another cause can be water hardness superior than 12°dF or if it contains many dissolved salts. Verify the rinse aid container and if it is adequate to the type of mains water. If the problem is not solved, contact the After-Sales Service.

  If water remains in the tank of your Smeg Dishwasher after pump-out, it could be due to a waste tube that is badly positioned or partially clogged. Check that the tube and drainage are not clogged and that the drainage is not positioned too high; see connection scheme.
