The AEG FAVORIT 403 Dishwasher has some known problems that occur often. Here are some easy to do solutions for the problems or error codes your AEG might be giving you.
The salt container needs refilling as indicated by the floater in the refill indicator window.
The rinse aid control light on the control panel flashes when rinse aid needs to be topped up.
The pilot light comes on when the On/Off button is depressed, indicating that the machine is on.
Possible causes include the door not being properly closed, the plug not properly inserted in the power socket, or a blown plug fuse.
Incorrect repositioning of the filters, or blocked spray arms, or insufficient detergent.
Dishes left too long inside the machine after the washing cycle has completed.
There is no salt or the softener is not adjusted to the water hardness, or the rinse aid has run out or is insufficient.
The dishwasher might not be level or properly installed.
