Frequently Asked Questions - WC430 CDA

How do I install the CDA WC430 dishwasher?

Ensure the appliance is level and securely connected to water supply and drain. Use the provided installation kit and follow the manual's step-by-step instructions. The electrical connection must be done by a qualified electrician.

What detergent should I use?

Use a quality dishwasher detergent (powder, gel, or tablets). For best results, use a combined product with salt and rinse aid. Adjust dosage based on water hardness.

How do I load the dishwasher for best cleaning?

Place larger items like pots and pans on the bottom rack, and glasses, cups, and small items on the top rack. Ensure that spray arms can rotate freely and that items are not blocking the detergent dispenser.

What does the error code E1 mean?

Error code E1 indicates a water inlet fault. Check that the water tap is fully open, the inlet hose is not kinked, and the filter at the hose connection is clean.

How often should I clean the filters?

Clean the microfilter and coarse filter after every few cycles, or at least once a month. Rinse under running water and remove any food debris to maintain performance.

Can I use regular table salt instead of dishwasher salt?

No, use only dishwasher salt (sodium chloride) specifically designed for water softeners. Table salt may contain additives that can damage the water softener system.

How do I activate the child lock?

Press and hold the Start and Program buttons simultaneously for 3 seconds until the child lock indicator lights up. Repeat to deactivate.

The dishwasher is not drying dishes properly. What can I do?

Ensure rinse aid is filled and the dosage is set correctly. Select a program with drying phase. Open the door slightly at the end of the cycle to allow steam to escape.

How do I reset the dishwasher?

To reset, press and hold the Start button for 5 seconds until the display turns off. Then close the door and select a new program.

Disposing of a household appliance separately avoids possible negative consequences for the environment and health. It also enables the constituent materials to be recovered, saving both energy and resources. As a reminder of the need to dispose of household appliances separately, the product is marked with a crossed-out wheeled dustbin.

Important

• Read the instructions prior to installation and use of the appliance.
• Do not lean or climb on the open dishwasher door to prevent damage.
• Close the dishwasher door after use to prevent accidents.
  • Use only detergents, salt and rinse aid specifically designed for dishwashers.
  • Do not put solvents in the dishwasher detergent compartment to prevent risk of explosion
• Only put dishwasher safe items into the dishwasher. If in doubt, check with the manufacturer of the items.
  Take care when loading the dishwasher to observe the recommendations for best loading practice, and also to ensure that sharp objects such as knives are placed blade down to prevent accidents.
• Do not open the dishwasher door when a programme is running. If it is necessary to do so, then open it only slightly to allow the dishwasher to pause the programme and prevent any water spilling out. Remember that the water in the dishwasher can be very hot when the programme is running.
• When the dishwasher is not in use, we recommend that you turn off the water supply at the supply tap and disconnect the main supply.

• If you are leaving the dishwasher for an extended period you should leave the door slightly open to prevent the formation of unpleasant smells.

• The plastic housing on the water inlet pipe contains an electrically operated valve. The wires that connect to this valve are inside the inlet hose. Do not cut through the inlet hose, and do not put the plastic housing in water.

• Children could get locked inside the appliance. Therefore when disposing of an old appliance, cut off the plug and set aside, and damage the door lock so that the door can no longer be closed.

Recommendations

• To reduce energy and water consumption, remove all dirt residues from the dishes prior to loading the dishwasher.
- Only run the dishwasher when fully loaded.
- Place hollow items (bowls, glasses and pans) face down in the basket.
- Do not put dishes or cutlery with tobacco ash, wax, lubricating grease or paint residues in the dishwasher.

Before First Use

• Set the water softener level as required by the water hardness in the area.
• Add 2kg of salt into the salt compartment and then fill with water to the top of the salt compartment.
• Remove all the packaging materials from the interior of the dishwasher.
• Fill the rinse aid compartment.
• Run a hot programme without any dishes in the dishwasher.

  When you close the door, the dishwasher will beep once and the programme will start automatically.

The Delay Timer

This dishwasher is equipped with a variable delay timer which can be set for 2, 4, 6, 8, 10 or 12 hours' duration.

• To set the delay timer, first switch the dishwasher on by pressing the power button. Then press the delay timer button. The delay timer will switch on and the selected delay timer indicator will illuminate.
• To change the duration, press the delay timer button again until the required time is shown on the indicators as shown below.

• Once the delay timer is set, then select the programme as described above.
- To cancel the delay timer before the programme has begun, press the delay timer button repeatedly until all the indicator lights go out.

Quick wash function

This dishwasher is equipped with a function that reduces the duration of the wash, minimising water and energy consumption.

• To set the quick wash function, select a programme as described above and then press the quick wash button so the quick wash indicator light is illuminated.
  • To cancel the quick wash function before the programme has begun, press the quick wash button and the quick wash indicator light will go out.

Cancelling or Changing a programme

If possible do not open the dishwasher door once the programme has started.

If it is necessary to cancel or change a programme once it has started, follow the steps below:

• First open the door slightly to reduce the risk of water spillage.
- Press the Programme Selection button for approximately three seconds until the Programme Indicators go out.
- Close the dishwasher door to allow the dishwasher to run a drain cycle.

Once the drain cycle is complete, the dishwasher can now be set to a new programme if necessary.

Please note: If the cancelled programme has already used the detergent and drained the wash water, the detergent dispenser must be refilled.

At the End of a Programme

When the dishwasher programme is complete, the dishwasher will beep six times and the Programme Indicators will go out. Open the dishwasher door.

• Press the Power button to switch off the dishwasher.
• Turn off the water tap and remove the plug from the power socket.

Please note: The dishwasher will automatically continue on the programme it has started if the door is opened or in the event of a power cut.

Detergent

To fill the detergent dispenser

1. Push the latch to open the dispenser.
2. Add the required amount of detergent to the main detergent dispenser. If your dishes are in need of an intensive wash, then add 5 cm ^3 of detergent into the prewash section of the dispenser.
3. Then close the detergent dispenser lid until the latch locks.

Please note: You should only use detergents designed specifically for use in dishwashers.

Combination detergents (e.g. 3-in-1 tablets) must not be used in any quick wash programme.

If using dishwasher tablets, always use the detergent compartment, do not put them in the main body of the dishwasher or in the cutlery basket. The solubility of dishwasher tablets can vary depending on the temperature and duration of the programme. As a result, it is recommended that powder detergents should be used in the shorter programmes to allow better performance.

CDA recommends the use of separate detergent, rinse aid and dishwasher salt rather than combination tablets as separates achieve better wash performance.

If you do use combination detergents, add salt and rinse aid to the dishwasher and then adjust the water hardness setting and rinse aid setting to the minimum. When you then use separate detergents again, you should fill the salt and rinse aid compartments, adjust the water hardness setting to the maximum and run an empty wash, then adjust the water hardness setting and the rinse aid setting to the appropriate level.

Salt

To ensure the best efficiency, the dishwasher needs soft water. Hard water means that lime residues remain on the dishes and the interior of the dishwasher, affecting performance. The softener system is designed to remove the ions that make the water hard to provide the best quality wash performance. This is achieved by using dishwasher salt.

To add dishwasher salt, follow the steps below:

1. Remove the lower dishwasher basket and then unscrew the salt compartment cap.
2. Fill the compartment with dishwasher salt (do not use table salt), carefully to prevent unnecessary spillage. Before first use, you should fill the compartment with 2kg of dishwasher salt and then fill up the salt compartment with water (up to the brim of the compartment) as shown in figure 3.
3. Replace the cap and the lower basket.

When the salt warning light on the control panel illuminates, you should refill the salt compartment with salt only – do not add water to the salt compartment after the first use.

You should run a programme immediately after adding dishwasher salt, to prevent any damage to the dishwasher systems.

Softener Adjustment

The efficiency of your dishwasher depends on the softness of the tap water. To ensure best efficiency, the dishwasher is equipped with a system that reduces the hardness in the mains water supply. The efficiency will increase when the system is correctly set. To find out the water harness level of your water supply contact your local water board.

To set the softener adjustment system unscrew the cap from the salt container and rotate the ring indicated in figure 4 according to the table below.

Rinse Aid

To fill the rinse aid compartment

1. Open the rinse aid compartment by turning and removing the cap as shown in figure5.
2. Fill the rinse aid compartment until the rinse aid indicator goes dark, as shown in figure 6 (where "a" indicates the compartment is empty, and "b" indicates the compartment is full).
3. Replace the cap, ensuring the markers on the cap line up with the compartment prior to screwing the cap back in place.

Rinse Aid Adjustment

The level of rinse aid use is preset to 3. You can adjust the level of rinse aid use by adjusting as shown in figure 7.

If water stains form on the dishes after a wash, the level should be increased. If blue stains which can be wiped away are left on the dishes after a wash, the level should be decreased.

Please note: Rinse aid ensures better quality wash results and increased drying performance.
