Frequently Asked Questions - WC431 CDA

How do I install the CDA WC431 dishwasher?

Installation should be done by a qualified professional. Ensure the appliance is level, connected to water supply (hot/cold), drainage, and power. Refer to the installation manual for detailed steps.

What detergent should I use?

Use dishwasher detergent in tablet, powder, or gel form. For best results, use a detergent with rinse aid and salt built-in, or add separately.

How do I clean the filter?

Remove the lower basket, unscrew the filter assembly (coarse and fine filters), rinse under running water, and reassemble. Clean at least once a month.

Why is the dishwasher not draining?

Check if the drain hose is kinked or blocked. Clean the filter. Ensure the sink drain is not blocked. If issue persists, contact a technician.

How do I adjust the water softener?

Locate the water hardness dial inside the dishwasher (usually near the filter). Set it according to your local water hardness. Test strips can be used to determine hardness.

What does the 'E' error code mean?

Error codes vary. Common codes: E1 (water inlet issue), E2 (drainage issue), E3 (heating problem). Refer to the manual's error code table for specific codes.

How do I load the cutlery basket?

Place knives, forks, and spoons with handles down to avoid injury, and separate them for better cleaning. Use the cutlery grid for optimal results.

Can I use regular table salt?

No, use only dishwasher regenerating salt (coarse). Regular table salt may damage the water softener.

How often should I run a cleaning cycle?

Run a dishwasher cleaner (e.g., Finish or similar) every 3-6 months to remove limescale and grease. Alternatively, use a cup of white vinegar on an empty cycle.

My dishes are not drying properly. What can I do?

Ensure rinse aid is filled. Use the extra dry option if available. Load dishes with concave surfaces facing down. Allow cool-down period before opening.

Detergent

To Fill the Detergent Compartment

1. Push the latch to open the compartment.
2. Add the required amount of detergent. The main detergent compartment “b” (figure 2) has lines to allow for specific amounts of detergent. These are marked at either 15 cm ^3 or

25 cm ^3 , to be used depending on how dirty the dishes are. If your dishes are in need of an intensive wash, then add 5 cm ^3 of detergent into the prewash section of the compartment “a” (figure 1).

1. Then close the detergent compartment 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 or half load 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, as shown in figure 3.

2. Fill the compartment with dishwasher salt (do not use table salt), carefully to prevent unnecessary spillage (figure 4). Before first use, you should fill the compartment with 1kg of dishwasher salt and then fill up the salt compartment with water (up to the brim of the compartment) as shown in figure 4.

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.

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

Only fill the salt compartment with water on first use.

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 hardness level of your water supply you can use the test strip supplied or alternatively contact your local water board.

• Open the testing strip (figure 5).
• Run water through the tap for one minute.
• Hold the testing strip in water for one second.
• Remove from the water and shake the test strip to remove excess water.
• Wait for one minute.
• Check the number of marks on the strip to see the level of water hardness.

If the hardness of the water you use is above 63 dE or if you are using well water; you are recommended to contact your local water board to confirm the water hardness level and to use filter and water refinement devices.

Please note: The level of water

hardness is preset to level 3.

1. Press and hold down the programme selection button

2. Press the Power button to switch on the dishwasher

3. Keep the programme selection button pressed until “8” shows on the display and then disappears.

4. After the 8 disappears the machine displays the last water hardness setting entered.

5. To adjust the level, press the programme selection button (3) until the required level is shown on the display, as listed in the Table of Water Hardness below.

6. To store the selected water hardness level, press the power button.

5	29 – 39	L5
6	40 - 63	L6

Rinse Aid

To Fill the Rinse Aid Compartment

1. Open the rinse aid compartment by turning and removing the cap as shown in figure 6.

2. Fill the rinse aid compartment until the rinse aid indicator goes dark, as shown in figure 7 (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 8.

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.

that the water outlet is not pushed too far into the waste standpipe. The lowest part of the water outlet should be level with the bottom basket of the dishwasher.

- When connecting to the sink, ensure that the waste pipe runs higher than the level of the sink bowl to prevent syphoning.

Fitting the Integrated Appliance Door

Where non-standard integrated appliance doors are supplied, additional fitting instructions are required to ensure compatibility with this product.

The machine is supplied with a fitting template and these instructions should be followed as normal.

However, the fitting template needs to be located lower down the fascia door; this is shown below.

The amount of offset, Y, depends on the height of the fascia door and can be calculated as X = 723mm.

For example, if you have a 731mm tall fascia door and are fitting a door to your dishwasher, then Y = 731-723 = 8mm.

Ensure that the hinge tensioners are adjusted to balance the weight of the door.
