Question about Miele Cat & Dog 326i Bagged Canister Vacuum
I have a Miele TT2000 which doesn't seem to suck as well as usual and the red warning light comes on after 5-10 minutes and shuts off. Seems to be overheating. Does anyone know what the problem is? All hoses seem to be clear.
That red warning light is the thermal cutout indicator. In the Mieles, the only way this happens is if you have restricted airflow.
Nothing can get into the motor chamber on these machines due to the design of the vacuum unless you have for some reason removed the pre-motor filter in the rear of the bag compartment.
To ensure that the problem is not in the canister, (which it most likely is not, but ruling it out is always a good idea,) disconnect the hose from the machine and turn it on. It is highly unlikely that the exhaust filter is impeding the airflow in any way, but if you are unsure, remove the exhaust filter prior to turning the machine on.
If the airflow seems normal, the problem lies somewhere in the hose, wand, or power head.
Check inside the power head immediately behind the brushroll, occasionally things can get lodged in there and block airflow. Then check the hose and wand for blockages as well. First, attach the hose only to the machine, and see if the airflow is still good. Then attach the wand and check for airflow again, and then attach the powerhead (ensuring that the brushroll is turned off before you feel for airflow.) If there is a clog somewhere you'll need to clear it: a good technique for this is to turn them backward and place them against the air inlet on the canister to pull out anything that may have become lodged in the air path.
If there is no clog anywhere in the machine, the final thing to check, which is very very uncommon; is the height adjust of your power head. Peoples' natural inclination is to smash the power head as low into the carpet as possible, which can restrict airflow and make it not clean as well, as well as causing the motor to overheat.
If everything checks out clear, it will need to be taken in to a warranty station for further evaluation.
Best of luck,

You may have to take some screws out, save them so you can put them all back. Check the impeller and cavity. If rocks and/or coins etc got sucked up the blades could be broken, this causes it to run out-of-balance. Debris can also get in there. Long stringy objects like hair, grass, straw, rug fibers, etc often gets wound the impeller shaft. This causes friction and binding, making it work harder.
