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 * The detergent or rinse aid cannot be withdrawn from the dedicated containers because of a worn or broken internal tube for detergent or rinse aid of the peristaltic pump.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.
