Question 3

What does the flashing glass symbol on the TEKA DW1 605 FI dishwasher mean and how can I resolve this issue?

Accepted Answer

The flashing glass symbol on your TEKA DW1 605 FI dishwasher primarily indicates a lack of rinse aid (rinse aid product). This light comes on when the rinse aid reservoir is nearly empty. Rinse aid is essential for ensuring optimal drying of your glasses and cutlery and for preventing the appearance of spots and limescale deposits.

To add rinse aid:

Open the dishwasher door;
Locate the rinse aid reservoir on the inner side of the door, on the right;
Turn the reservoir cap counterclockwise a quarter turn and remove it;
Pour the rinse aid until the reservoir is completely full (approximately 140 ml). The optical indicator on the side of the cap should be completely covered;
Reattach the cap by turning it clockwise;
Wipe up any possible rinse aid spills with a soft cloth to avoid excessive foaming.

After adding rinse aid, the glass indicator should turn off after a few wash cycles. If you have set the dispenser to a position that is too high, the product may leave white marks or make the glasses sticky. Adjust the dispenser selector to a lower position if this issue occurs.

If the glass symbol continues to flash despite adding rinse aid, or if it flashes immediately after filling, check that the reservoir cap is properly closed and dry. A loose or wet cap may trigger the rinse aid shortage sensor.

Note: If the light persists but you have filled the reservoir and closed the cap correctly, it may be a problem of water accumulation (overflow) or insufficient drainage. In this case, check that the drain hose is not kinked or blocked, that the filters are not clogged, and that the drainage siphon is functioning properly. If the problem persists after these checks, contact a certified TEKA technician.
