Frequently Asked Questions - TKA8A683 BOSCH

How to descale my Bosch TKA8A683 coffee maker?

Use a suitable descaling agent or diluted white vinegar (1/3 vinegar, 2/3 water). Pour into the tank, run a cycle without coffee, rinse with 2 cycles of clear water. Repeat every 3 months.

Why isn't the coffee hot enough?

Check that the warming plate is clean and the carafe is properly positioned. If the problem persists, descale the appliance. A serving temperature of about 80°C is normal.

What type of ground coffee to use?

Use a medium grind for drip coffee makers. Avoid too fine grinds that clog the filter. The recommended dose is about 7 g per cup.

How to clean the permanent filter?

Rinse the filter under hot water after each use. For deep cleaning, soak it in soapy water then brush it. Do not put in the dishwasher.

The coffee maker stops before the brewing is complete, what to do?

This may be due to excess limescale or a clogged filter. Descale the appliance and clean the filter. Also check that the tank is properly filled.

Can I use paper filters?

Yes, the coffee maker accepts size #4 paper filters. Place the filter in the filter holder before adding coffee. You can alternate with the permanent filter.

How to adjust the auto shut-off?

The auto shut-off is preprogrammed to about 40 minutes after the end of brewing. It is not adjustable. To extend the keep-warm function, use the manual keep-warm function if available.

The red light is flashing, what does it mean?

The red light usually flashes to indicate a need for descaling. Refer to the user manual for the descaling procedure specific to this model.

The carafe fills poorly, drip by drip?

Check that the anti-drip system is working properly. Clean the anti-drip valve under the filter holder. Also ensure that the carafe lid is properly in place.

Where can I find spare parts?

Spare parts (carafe, filter, seals) are available from authorized Bosch dealers or on the official website. Use the reference TKA8A683 to find compatible parts.

General information

■ Fill water tank with clean, cold water only. Never add milk or beverages such as tea or coffee since this will damage the appliance.
■ Never fill water tank above the marking "8 ☐" (TKA8A68.) or "10 ☐" (TKA863.).
■ Use coffee with a medium grind (approx. 6 g per cup).

■ Do not brew less than the minimum amount of three cups since the coffee will not have the desired strength and temperature (1 cup = approx. 125 ml).
■ Never remove the carafe while the machine is brewing coffee since this may cause the filter holder to overflow.
■ Make sure that carafe's lid is closed when you place the carafe on the coffee machine.
■ Do not use other carafes since the special drip protector will block the coffee from flowing into the receptacle.
■ Some water accumulation on the filter holder is normal; it does not indicate that the coffee machine is defective.

Before using for the first time

■ Remove any stickers or film.
■ Pull enough of the power cable out of the storage compartment and plug in.

■ Press ON/OFF switch ①; the display flashes.
■ Set the current time by pressing button h for the hour and button min for the minute.

Note: You can change the time. Press buttons h and min simultaneously and set the correct time.

■ To clean, fill water tank with 6 cups of water and replace it. Press the start button; cleaning program starts.
■ Repeat the cleaning process.

Note: You may notice a “new machine” smell; this is normal. If this is the case, fill with a vinegar solution (1 cup of vinegar for 5 cups of water) and run the cleaning program. Next, rinse the machine twice with 6 cups of water.

■ Clean the carafe thoroughly.

Brewing coffee

■ Remove the water tank, fill it with water and replace it.
■ Flip out the filter housing.
■ Insert a 1x4 paper filter in the filter holder and add the desired amount of coffee.

■ Flip back the filter housing until it engages.
■ Place the carafe with the lid closed under the filter housing.

■ Press button start to begin the brewing process.
■ At the same time, the auto off function is activated; the display lights up.

TKA863. only

Info: The appliance has an automatic auto off (power save) function, which switches the appliance to power-saving mode around 40 minutes after the brewing process is complete.

TKA8A68. only

Info: The appliance has an automatic auto off (power save) function, which switches the appliance to power-saving mode a few minutes after the brewing process is complete.

Tip: If you rinse out the thermos carafe with hot water before use, the coffee will stay warm even longer.

Important: When the brewing process is complete, wait a moment until all the coffee has run through the filter and into the carafe.

Let the machine cool down for five minutes before brewing a fresh pot.

Timer function

This coffee machine is equipped with a timer. It lets you set the time at which the machine will automatically start the brewing process.
The timer works only if the machine is turned on or in power-save mode.

■ The clock must be set to the correct current time.

■ Press and hold down the button prog while programming the timer (Fig. a).
■ Use button h to set the hour and button min to set the minute at which you want the brewing to start (Figs. b and c).
■ Release button prog to save the start time. The display shows a little clock to indicate that the timer function is activated.
■ Fill the machine with water and coffee as usual and place the carafe under the filter housing.

■ The brewing process will start automatically at the set time; the little clock disappears.

Note: To check the programmed time, press and hold down the button prog.

Turning the timer function on/off

Press button prog. If the little clock lights up, the timer function is on. If the little clock turns off, the timer function is off.

Note: If you turn off the coffee machine with ON/OFF switch ① or the power supply is interrupted (plug not plugged in, power failure), the clock and timer settings will be stored for approximately four days. If the power interruption lasts longer, you must reset the clock.

Tip: If you do not use the appliance for a longer period of time, turn it off with ON/OFF switch ①.

Low water indicator

This coffee machine senses if the water volume in the water tank is low (less than approx. 4 cups). If the water level is low,

lights up and the machine automatically increases the brewing time. This ensures that the coffee retains its ideal flavour.

Thermos carafe

TKA8A68. only

Important: Never use the carafe for keeping dairy products or baby food warm, because bacteria may form. Do not heat the carafe in the microwave or in a regular oven.

Never use the carafe to store or transport carbonated beverages. Carefully rinse the carafe after each use.

To keep the lid from permanently vacuum-sealing itself shut, it was designed to not close hermetically. Since the thermos carafe may leak, you should always store and transport it in an upright position. The thermos carafe holds approximately 8 cups.

The lid of the thermos carafe can be opened with the release switch.

■ Open lid (Fig. d)
■ Close lid (Fig. e)
■ Remove lid (Fig. f)

Coffee-making tips

Store ground coffee in a cool place; you can also freeze it. Once a package of coffee has been opened, close it tightly to maintain its aroma.

How the coffee beans are roasted affects their taste and aroma.

Darker roast = more flavour

Lighter roast = more acidity

Cleaning

Never immerse the device in water or place it in the dishwasher! Don't steam-clean the appliance. Unplug the appliance before cleaning it.

■ Clean all parts that came into contact with coffee after each use.
- Clean the coffee machine's exterior with a damp cloth; do not use strong or abrasive cleaning agents.
- Clean the water tank under running water; don't use a firm brush.

TKA863. only

■ The glass carafe and its lid are dishwasher-safe.

TKA8A68. only

■ Rinse out the thermos carafe and lid and wipe its exterior clean with a damp cloth. Do not submerse the carafe in the dishwater or place it in the dishwasher.

Tip: Stubborn water deposits can be removed with a solution of baking soda, dishwasher powder or effervescent denture cleaning tablets.

■ To prevent bad odors and bacteria from forming, store the thermos carafe with the lid open.

Descaling

This appliance is equipped with an automatic descaling indicator. If calc indicator lights up, the machine needs to be descaled.

Regular descaling

■ makes your appliance last longer,
■ ensures proper function,
■ prevents excessive steam,
■ speeds up the brewing process,
■ saves energy.

Descale the machine with a commercial descaling agent.

■ The appliance must be switched on.
■ Make sure that carafe's lid is closed when you place the carafe on the coffee machine.
- Prepare the descaling solution according to the manufacturer's instructions and pour it into the water tank.

Warning: Do not fill with more than 6 cups.

■ Press and hold down the button descale calc for at least 2 seconds. The descaling process starts.

■ The program interrupts the process several times for a few minutes in order to let the descaling agent penetrate the deposits. The entire descaling process takes about 30 minutes. When the program is running, the display calc will blink.

■ When the descaling process is complete, the display calc will no longer light up. Operate the machine twice using clean water, without coffee. Do not fill the tank with more than 6 cups of water.

■ Carefully rinse all removable parts and the carafe.

Troubleshooting

The machine takes noticeably longer or switches itself off before the brewing process is complete.

– The machine needs descaling.

■ Descale the machine as per the instructions. To start the descaling program, press and hold button calc for at least two seconds.

Tip: If your water is very hard, descale the coffee machine more frequently than requested by the calc indicator.

The drip stop leaks.
