Stuart's Bosch Tassimo Hot Drinks Machine Forum

I have an older Tassimo TAS1000 (made in Slovenia!) that I bought about 6 years ago. It has worked perfectly and still does, but I am curious about the inner workings and would like to open it up and take a look. The body design seems almost identical to the T46 and T65. I have tried sliding the side panels toward the rear, but even when I apply a lot of force, they don't budge. I also read somewhere that inserting a screwdriver between the side panel and case at the rear about halfway up would release a catch inside, but this hasn't helped either. I have run a dull knife completely around the seams to ensure they aren't being glued by lime deposits. Any suggestions?

Hi,

I am pretty sure all you need to do to take a side panel off is to, as you say, insert a screwdriver about half way up and then slide the whole panel towards the rear. It should release.

Take a look at the 3rd photo on http://www.stuartdalby.co.uk/miscellaneous/tassimo_repair/index.php with the fixing holes circled. You can see from the shape of the holes how you only need to slide the panel back about 1cm and then the cover should just lift off.

Have another go and let us know how you get on,

Well, I finally got it. I had to use an incredible amount of force to push the panels to the rear. I still have no feeling in my fingertips! I will probably do a little filing of the slots or slather some grease around the holes that engage the pins, because I would not want to go through that effort again. But it is fantastic to be able to see all the workings. It looks just like new inside. Even better, it looks exactly like your photos. Thanks, Stuart.

Excellent news! Thanks for letting us know that you managed to get in,

Stuart

Well, after reading this and using the above described method, I am pretty sure I just broke some little tab somewhere inside (I can hear it rattling around) and I still haven't got it opened. Any suggestions?

Jep, just got it the rest of the way and 3 little tabs are broken on the panel that I slid back.

OK, now that I'm in, does anyone know how to trouble shoot why the descaling cycle won't start? I don't see any loose hoses.

Sorry to hear you broke 3 of the tabs on the side panel. These machines are not really designed to be user serviceable.

How are you trying to start the descaling cycle? What lights are illuminated on the machine when you put the service disc in?

Hi Stuart,
The yellow light comes on when I set the on/off switch to on. When I insert the service pod with the barcode and hold down the program button for 10 seconds it just stays yellow. nothing happens. The microswitch to the left of the nozzle is clicking when it is supposed to and a red light comes on if I click it by hand, indicating that the barcode scanner is operating. Is there a circuit breaker or a fuse somewhere that I can check? I'm wondering if the heating element or the pump might be burned out.

BTW Stuart, It's no a big deal with the tabs, it was the 4 little triangular tabs (per side) that are supposed to prevent access. There is no way in without breaking the tabs. As for the big one in the middle on the bottom of the panel, I would suggest using a screwdriver and trying to avoid breaking that one. It looks like it is designed to keep the panel from just falling off once it has been replaced. Here in Sweden, we have 220v 50Hz and you don't want anyone to get killed while making a latte...

Is it just the descale programme which doesn't start or can you still brew normal t discs?

The yellow/amber light is the normal standby light. Do you not also see a red descale light?

Sounds to me like the machine is not able to read the barcode. Might be worth giving the barcode and the barcode scanner window a wipe.

I don't think it's a fuse/circuit breaker type thing; the yellow light coming on proves it has power. If it was a failed pump I think you would at least hear it try to pump.

Let us know how you get on,
Stuart

It doesn't brew coffee either. When I start it, it flashes red and green for about half a second and then goes to yellow (amber) like it's supposed to. Then instead of turning green to show it's ready to start, it just stays yellow (left side of start button) no matter what kind of pod I insert. If I open it and manually click the micro switch, a red light in the barcode reader flashes and then goes out, but not when I insert a pod and close it. If I do that, It just stays yellow, but I can hear the switch click. Do you know if there is a way to test the circuit board? Or maybe there is some kind of troubleshooting protocol to follow based on symptoms?

When you press the microswitch manually, the red barcode scanner light should light up steady, not flash like you say. If you continue to hold the microswitch it should stay on for about 10 seconds before going out.

I don't know how to test the circuit board, sorry. Maybe it is just the barcode reading module which is faulty?
