Bosch CTES32 Coffee Machine: Cold Water Issue, Possible Heater Damage?

Question

Hello, I have a problem with the Bosch CTES32 coffee machine, namely the coffee machine does not heat up, and everything else works properly. When making coffee, the coffee machine grinds the beans, then releases the water only cold, when you try to release hot water, the message Water heating...

You need to empty the coffee bean container, unhook the 2 optical presence sensors from the hooks, bend the hooks around the grinder and lift the whole thing up. Of course, the casing around the machine must be removed. It will be much easier.

Please do not pick me up wrong, but it seems to me after the post that you do not have the skills to use a multimeter?

Because without it, you can't do it ...

Most often one of the thermal fuses is damaged, but it happens when the electronic board is damaged.

I warmly welcome,
You're right, I'm not an eagle in this field, but if I measured the heater correctly, it showed infinity on the meter, so it will probably be replaced, I'm still wondering about the very low voltage on the heater (the voltage is only a few volts and here you are right that it could also be damaged) the tile is subject to check only) Regards

Added after 3 [minutes]:

I will add that the voltage at the output from the switch is 240V and this also enters the board and the output from the board is just a few V, as I wrote earlier

This is where this barrier comes in.

Unplug the wires that lead the current to the heater and then measure how much V comes ...
Of course, the heater's thermal fuses must be taken into account. If it turns out that one of them is damaged, it is also recommended to replace the ntc sensor, which is responsible for maintaining the right temperature.
I just can't remember whether there is direct or alternating current going there ...
If it turned out from this map that there is no need to check the relay on the electric plate in the first relationship, which is responsible for switching on the heater.

Hello, I ordered the entire heater. I will try to replace it, let's see if something changes best regards

bosman116 · Answer

kesy1 check the fuses at the heater are in order. If one of them is damaged, there is a high probability that it will fry it again after inserting a new heater.

Hello, I'd love to do it but I have no idea how to go about it maybe some hint which fuses are and how to check them

bosman116 · Answer

We know how to measure ...?

kesy1 · Answer

something there sometime they need to be removed somehow and we measure with an ohmmeter, of course?

bosman116 · Answer

Climb not necessarily, but that's right with an ohmmeter - Uncle Google will help.

kesy1 · Answer

Hello, I measured the fuses and you were right one (the one on the power supply) is damaged, the other is ok (about 1.5 ohms). As for the heater, measured outside the fuses is also ok (about 35 ohms). I have already ordered the heater, but now I'm afraid to insert it, since there is a chance that it will fry it right away. Where to look for the problem now ???
best regards

bosman116 · Answer

When you insert a new heater and the coffee maker, after inserting the plug into the contact, it will heat it up, i.e. that the power module still has a short circuit in the system. You can check it on the old heater by strapping the wires, omitting the fuse. Just be careful that they do not touch the metal parts of the coffee machine.

Hello, can anyone advise you on how to remove this coffee container. I can't cope with the disassembly of the top casing of the TES50321RW / 12 coffee machine and without it the ntc sensor cannot be replaced. maybe someone knows some other way Please help

kesy1 · Answer

Thank you for your help. The coffee machine has been repaired, the heater has been replaced and so far everything works best regards
