why is part of a detergent tablet left in my Smeg dishwasher?
a combination tablet may not dissolve fully during the selected wash. residue can call for checking detergent and programme suitability rather than immediately replacing a dispenser.
model scope: for Smeg dishwashers using tablets; choose only a wash suitable for the loaded items.
read the tablet directions and the dishwasher's programme guidance. a suitable hotter full wash may help only where the machine offers it and every loaded item tolerates it. do not expose heat-sensitive items to an unsuitable programme just to dissolve detergent.
the linked guide covers those detergent and programme checks, not a dispenser repair. if residue persists or the dispenser is stuck, arrange assessment rather than dismantling the door. the programme must suit the load and model.
first checks
- compare tablet and programme directions
check the selected programme against detergent instructions and item heat tolerance before changing the wash.
possible causes
- tablet formulation not dissolving fully during the chosen wash
