Frequently Asked Questions - GSXK 7451/3 BAUKNECHT

How do I adjust the water hardness setting?

Switch on the appliance, select program 2, then press the Start button for at least 5 seconds until the Start indicator flashes. The flashing frequency indicates the current hardness level (1-7). Press Start again to increase the setting; it cycles back to 1 after 7. Switch off to save. Refer to the hardness table in the manual.

What should I do if I see white streaks on dishes?

White streaks usually indicate too high a rinse aid dosage. Reduce the dosage by turning the dial inside the rinse aid dispenser to a lower setting (1-3). Use a coin to turn the dial.

How do I clean the filters?

Rotate the microfilter counter-clockwise and remove it. Take out the wide-mesh and fine-mesh filters. Rinse all under running water. Reassemble by inserting the wide-mesh into the microfilter until it clicks, then the fine-mesh under the two tabs, and rotate clockwise until the dashed lines align.

Can I use tablet detergents?

Yes, you can use all-in-one tablets that include salt and rinse aid. Follow the detergent manufacturer's instructions. Place the tablet in compartment (A) for programs without pre-rinse, or follow package directions for pre-rinse programs.

How do I fill the salt container for the first time?

Remove the lower rack, unscrew the cap. Pour water into the container to the rim (only for first use), then add regeneration salt until full (1.5-2 kg). Stir gently, screw cap back on, and run a wash program immediately to avoid corrosion.

Why is the dishwasher not drying dishes properly?

The rinse aid dosage may be too low. Open the rinse aid dispenser and turn the dial to a higher setting (5-6). Also ensure you use a suitable rinse aid and that the dishwasher is loaded correctly to allow proper air circulation.

What does the water stop system do?

The water stop system protects against flooding by shutting off water supply if a leak is detected. It includes electrical components in the inlet hose; do not cut the hose or immerse the plastic casing in water.

How do I clean the spray arms?

For the upper arm, loosen the fixing nut counter-clockwise and pull down. For the lower arm, loosen the nut and pull upward. Rinse the nozzles under water. Remount by aligning and tightening the nut clockwise until it clicks. Ensure they rotate freely.

Is the dishwasher safe to use with hot water supply?

Yes, if ecological energy sources are available, you can connect to hot water up to 60°C. Ensure the inlet hose is suitable (marked accordingly) and refer to the installation instructions. This can save energy.

What should I do if the dishwasher is not draining properly?

Check that the drain hose is not kinked or blocked. Ensure the filter assembly is clean. Verify that the sink siphon (if connected) is not obstructed. If the problem persists, contact a qualified technician.
