Braun Aromaster KF 440 Troubleshooting

10 Cup Coffee Maker, 900W, identified by KF440. Made in Germany.

Coffee maker will not turn on ¶ 

The coffee maker does not respond when the power is switched on.

Device unplugged ¶ 

Make sure the coffee maker is plugged into a working electrical outlet. Try to plug coffee maker into at least two separate outlets to make sure the power outlet is functioning correctly.

Damaged power cord ¶ 

Visually look over the power cord to make sure there are no obvious breaks, cuts, or damage done to cord.

Circuit board malfunction ¶ 

The KF 440 is equipped with a circuit board that controls the functions of the coffee maker. Visually look over the circuit board and see if there are any burnt or broken components.

Coffee maker turns on but will not brew coffee ¶ 

The power switch is on (red light appears), but no coffee is produced.

Water reservoir is empty ¶ 

Make sure the water reservoir is filled with water.

Coffee pot not correctly in place ¶ 

The coffee pot needs to sit correctly and fully onto the hotplate for coffee to brew.

Faulty filter basket components ¶ 

The filter basket has a spring and ball assembly, which allows coffee to flow into the pot and stops flow when the pot is removed. If this assembly is broken, the coffee maker will not brew correctly. Refer to the Braun Aromaster KF440 Filter Basket Replacement Guide.

Coffee maker will only brew water ¶ 

The coffee maker only produces hot water.

Empty filter basket ¶ 

Make sure coffee grounds are in the filter basket.

Coffee maker brews slowly ¶ 

The coffee maker is producing coffee, but at a slower than average pace.

Coffee maker needs to be cleaned ¶ 

In addition to coffee grounds, the coffeemaker can build up calcium and mineral deposits. The coffeemaker can be cleaned by running the coffee maker once with a water-vinegar solution (1:1) and another time with just water.

Coffee maker’s one-way inline valve is clogged ¶ 

The KF 440 is equipped with a one-way valve to aid in brewing. This valve can become clogged with residues, causing the coffee maker to brew very slowly. Refer to the Braun Aromaster KF440 one-way valve Replacement

Brewed coffee is not hot ¶ 

The coffee maker brews coffee normally, but the coffee from the carafe is not hot.

Automatic shut-off switch has been activated ¶ 

The automatic shut off switch will turn the coffee maker off after a given amount of time for safety reasons. Most coffee makers default shut off time is 2 hours unless otherwise manually programmed for a different time.

Faulty heating element ¶ 

The heating element, which heats the coffee to the desired temperature, can fail. This failure would cause the coffee maker to brew cold coffee. Refer to the Braun Aromaster KF440 Internal Tubing Replacement Guide

Coffee grounds appear in brewed coffee ¶ 

There are coffee grounds in the bottom of the carafe.

Paper filter not properly seated ¶ 

The paper filter needs to sit in the basket correctly for the brewing process. If the sides of the filter are folded over and not in contact with the filter basket, coffee grounds will leak through the basket and into the coffee pot. If this happens, clean the filter basket and coffee pot, then install a new filter that is correctly positioned.

Damaged filter basket ¶ 

Visually check the filter basket for cracks or holes that could be allowing coffee grounds to leak into the coffee pot. If cracks or holes are detected refer to the KF 440 filter basket replacement guide.

Water appears around the base of the coffee maker ¶ 

Water leaks beneath the coffee maker and on to the countertop.

Too much water in reservoir ¶ 

Too much water can be poured into the coffee maker’s reservoir. This would cause water to leak out of coffee maker, leaving a puddle of water around it.

Internal hoses are cracked or Broken ¶ 

The tubing inside of the coffee maker can become cracked or broken over time , causing the coffee maker to leak water . Refer to the Braun Aromaster KF440 Heating Element Replacemen

Someone brewed coffee in my pot without using a filter. Now it won't work. The company said it's unfixable. Any suggestions?
