Tassimo troubleshooting red light / Tassimo not working red light / Bosch Tassimo manual red light

This one is actually quite easy to fix.  The red light comes on when your pod coffee machine needs descaling, we have an excellent guide on how to fix this with a video tutorial or you can follow the instructions below.

  1. Fill a measuring cup with 2 cups of hot water.
  2. Mix in the Tassimo descaler.  You can get Tassimo descaling tablets at places like Amazon pretty cheap.
  3. Pour the water and descaler into the empty water tank.
  4. Put your yellow cleaning T-disc in the disk draw and close the draw. Use the measuring cup to catch the waste water from the spout.  If you do not have a cleaning T-disc you can pick one up on Amazon pretty cheap.
  5. Push and hold the start button for about 5 seconds, until you see the red and green light flash.
  6. Wait 20 minutes for the cleaning cycle to complete.
  7. Once the cleaning cycle is completed, the red light will turn off.
  8. Add fresh water to the water tank and run the brewing cycle 4 times to completely clean the pipes and remove any taste from the descaling tablets.

Your pod coffee machine is now as good as new and good to go.

Tassimo red light flashing

The water tap light flashes red when either the water tank needs refilling, the water level is too low to make a drink, or when the tank is not fixed correctly in place.

  • Check that the water tank is fitted correctly in place.
  • Make sure the tank has sufficient water (never use carbonated water as the coffee maker runs at high pressure and will most definitely break).

Tassimo not working orange light

Again, this is fairly common and nice and easy to fix.  Sometimes milk or coffee/tea/hot chocolate etc can leak from your Tassimo pods and get onto the barcode scanner, this means that your machine cannot read the barcode and so gives you the orange light.  Follow the instructions below and you should be up and running in no time.

  • Clean the barcode reader with a damp soft cloth

Some people have found that this issue happens when you insert the Tassimo pod prior to turning your pod coffee machine on.

  • Simply turn on your machine prior to inserting the Tassimo pod

Tassimo reset

This one can be annoying but easy to fix if you know how!  If you find that your machine goes straight from auto to standby without completing the brewing cycle, or you need to reset your machine for some other reason, follow the instructions below.

  1. Unplug your coffee machine.
  2. Prior to turning your coffee machine back on, push and hold the start button.
  3. Turn on your machine and then release the start button.
  4. Insert a T-disc and close lid.
  5. Press the start button when your coffee machine goes to auto.

You should now be good to go.

Tassimo not brewing full cup / Tassimo only makes half cup

An easy fix to this one as well as the solution is all about cleaning.  This could be caused by too much limescale and thus you need to follow the steps above to descale your coffee machine.  A good way to spot this, other than the red light, is when you see that the overflow which is behind the splash back is leaking.  Either way, follow the descaling tips above and you should now get a full cup of your favourite drink, just like when you first bought it.

Or, you could have a blocked pipe or funnel.

  • Make sure you clean all removable parts regularly, all but the water tank are dishwasher-safe which makes this incredibly easy.
  • Toothpick – sometimes the funnel where the water comes out of can get blocked by coffee granules, you can remove the coffee granules with a toothpick to allow full water flow again.

Making sure you keep on top of cleaning your pod coffee machine will mean that it functions for you perfectly every time you need it.

Tassimo not heating water

This one is tricky as it is most likely a faulty heating element which will need to be replaced or you will need to buy a new Tassimo coffee machine.  However, before you try to replace the heating element or buy a new pod coffee machine, please do try and descale and clean all the parts thoroughly first.

  • The heating element is not designed to be replaced so if you attempt to do this, make sure you know what you are doing – not advised.
  • Unfortunately, Tassimo coffee machines are built as throwaway products and are not designed to have this level of maintenance – our advice is to buy a new one.

Sorry that we could not help more with this, but we can tell you how to prolong the life of your water heater element.

  • Do not add water to the reservoir unless the coffee maker has been turned off for at least five minutes.  If the reservoir is empty and the coffee maker is left on, the element continues to heat and becomes super hot.  When you add cold water it is likely to cause damage to the element.  Do this many times and the element will eventually break.

Tassimo lid jammed

The lid of your Tassimo machine can get jammed or stuck when the high pressure in the system is not automatically released.

Firstly, be very careful not to try and force the lid open, as you can break it fairly easily.

There is a solution, but it is a bit of a hassle. Follow these steps and you will be up and running in no time.

  1. how to fix a tassimo machine jammed lidRemove the left side of the coffee maker (left side as you look at it from the front).
  2. Remove the hose or pipe which fits on to the valve. You can see what this looks like from the picture, but this could vary depending on the model you have.

This releases the pressure built up in the system and you should now find that you can open the lid again.

  1. Reattach the hose and cable tie.
  2. Clip the left hand side panel back on.

You should now be able to use your tassimo coffee machine without any issues.

Tassimo not pumping water

This is another issue which requires a little more work to fix, but it is fairly easy and will save you paying for either a repair or a new coffee machine, so worth a bit of hassle.

Essentially, the problem is that some dirt or debris has blocked the pressure valve which connects to the water tank and it will no longer pump water. To fix this we need to clean that out and we should then be brewing again in no time.  Follow these easy steps to complete this repair.

  1. Remove the left side of the coffee maker (left side as you look at it from the front).
  2. Find the hose or pipe which connects the water container to the bottom of the heater.
  3. Turn the valve 30 degrees.  Use needle nose pliers if you have them.
  4. Gently remove the valve cover and then remove the spring.
  5. Clear out any dirt and debris which might be blocking the water.
  6. Put the valve back together and reattach.
  7. Clip the left hand side panel back on.

If I were performing this fix, I would leave the side off for a couple of brews, to make sure that it was working properly, and when I was happy I would then reattach the side.

I have not used my Tassimo brewer in a while, what do I need to do?

If you have not used your tassimo machine in a week or more, it would be a good idea to rinse the water tank and refill it with clean water.  You should use the service t-disc to start the machine and run it through a brewing cycle to clean the internal pipes and ensure your drinks taste great.

Water dripping from the brewing unit

There is an easy solution to this problem.  Either the tassimo pod is defective or the piercing unit is not properly aligned or inserted.

  1. Remove the pod.
  2. Check that the unit is clean.  Always a good idea to clean it to be on the safe side.
  3. Put the pod back in.
  4. Check to see that the piercing unit is properly aligned.  If not, insert it correctly.

This should fix any dripping issues that you get from the brewing head.
