Most coffee maker repairs do not require professional skills or tools. All you need is patience and a reliable source of information.
There is every possibility that you will be able to fix your Tassimo coffee maker on your own if you follow the instructions you see below. Mind the model of the coffee maker you use to identify the right troubleshooting table for your machine.
There might be several causes why your tassimo not working:
This situation may occur due to various reasons:
The most likely cause of the stop is limescale building up in the container and on other components. The following video describes the descaling procedure.
The Tassimo lid gets jammed due to high pressure in the system, so you need to decompress it. For more details, please, view the following video.
Please, do not try to fix it yourself unless you have experience in that. Do not do it unless the warranty period has expired!
You can try to clean the bar code plate with a cotton stick. Repeat the procedure from time to time.
This is far less than a grave problem. The pressure valve draws water from the pump back into the container when pressure increases dramatically. This happens when debris get into the valve, so it fails to close and lets water back into the tank. As a result, your Tassimo won’t pump water. To fix it, remove the gray panel on the left (when you are facing the front panel). With the help of screwdrivers of other long and flat objects, lift the panel and press it toward the machine’s back. Remove the panel and locate the tube that connects the heater’s bottom with the water container. Pick the valve at the heater’s bottom with a pair of pliers or pincers and turn it 30 degrees clockwise. Pull it gently until the valve cover comes off and pull out the spring and the valve itself. Remove the debris, if any, and reassemble the valve. To ensure that there is no debris or dirt any more, you can run the machine without closing the panel for a while.
Tassimo error codes signal either a necessity of descaling or lack of water in the tank.
Tassimo red light
Most likely, the device needs to be descaled. Open the water tank and check the heating element for limescale buildup.
It should be noted that older brewers do not have a descale warning light. Be sure to clean and descale your brewer once per three months. This will prevent damage and prolong its life.
THE RED INDICATOR LIGHT IS BLINKING
This light comes on and flashes when water level in the tank is too low. In this case, the machine will not be able to make a drink. Also, the error appears when the tank is not positioned properly. Fill the tank and be sure that the water is fresh, clean and not softened.
Error messages in Tassimo coffeemakers appear in the form of lights burning or flashing.
If you see the red light burning steadily, the machine needs to be descaled.
If the red light is blinking, the tank needs to be refilled with water: the machine will not make coffee unless there is enough water in the tank.
If all the lights are on, the system requires a serious repair. Please, use professional help.
