Red light comes on and switches itself off

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.

Re: Red light comes on and switches itself off

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,

Re: Red light comes on and switches itself off

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.

The red filter light will not reset after replacing the filter on my Miele S5980

Hi There, I actually did a repair on this problem only a couple of weeks ago. The problem could be that the small lever that pushes on the reset button on the circuit board is bent or broken. The little button costs about $10 from memory and certainly a whole lot cheaper than the board itself which is $234. Just to clarify in my case there was nothing wrong with the board, I was able to manually push the reset switch on the board and replace the tiny lever and problem was solved.

Miele S7210 red light on

You may have more dog hair in the main hose. Pull the hose out of the body, turn the lower hose swivel 90 degrees parallel to the floor and twist the hose off. You will see where to remove it at the swivel. Also check the port door on the back of the vacuum near the bottom of the upper section. It can be looks like a parallelogram with 2 plastic screws, twist the screws half a rotation and gently pry the cover off. After clearing out any debris, replace the cover and fasten the screws. A small LED flashlight will be very handy for checking all of the ports and hoses.

Our miele red star(s314i) vacuum was running great and quit suddenly. It had not been running for a very long time and just quit. Newish bag, no clogs in hose and doesn't seem overly hot. the over heated...

Ok, so if the cord test didn't fix the problem, then it sounds like either the plug has gone bad, or the switch. The plug is a very common problem to go bad, and can be caused by just simply yanking the plug out of the wall, or putting too much tension on the cord while you're vacuuming. Here's a link showing how to replace a plug on your Miele. You may purchase a plug at a Home Depot for very cheap. If this doesn't fix your problem, then it is either going to be the entire cord reel assembly that's gone bad, or the switch. The plug is the easiest, cheapest next best option, so hopefully this is your problem. Here's a link on how to change the plug out;

Please just use the comment field again if this doesn't fix it, and I'll walk you through step by step the more detailed process of replacing the cord reel.

I have a Miele turbo plus solaris and the red warning light is on. This prevents the vacuum from working. I have changed the bag so I am not sure what to do?

I had this problem with a different model. It's caused by a thermal cutout switch in the motor. My problem was a result of a filter being removed and the bag not seated correctly, hence dirt got into the motor and clogged the turbine, reducing airflow through the motor and causing the over heating.

If your motor runs at all, you probably have a blockage. Replace the filter inside the bag compartment just before the motor vent. Check the hose isn't blocked. Check the exit air filter.

If your turbine is clogged, it's a big disassembly job best done by a professional. If you really want to know how to cure it and feel you can tackle it yourself, email me. alan_at_alanjohnston_dot_com.

If your motor doesn't run at all and the light just quietly comes on, you have a break somewhere in the thermal protection circuit, either in the wiring (unlikely) or inside the circuitry buried inside the motor itself. I had an open on the thermal switch where the combination of heat and vibration deoldered the thermal switch from its board.

Hope this helps.

Miele s314 red star-motor stopped working-on/off switch broken?

Most likely the problem is with the cord winder. This is the most common problem with Mieles. It is actually the most common problem with any vacuum with a cord winder. A Miele repair center should not change you to look at the vacuum and tell you what is wrong with it. The Red Star was a great model and if the powerhead is still in goood condition I would get the vacuum repaired. If it is the cordwinder they can usually be repaired and it should cost about $75.00. If you need a new cord winder this will cost about $150.00. The top piece can be pryed off, however if it feels like it is switching than it is not jammed.

Stopped working - warning light on

There is an electronic circuit board on the motor that may have gone bad and will have to replaced, part # 06836740 and sells for around $75.00, for model S516. But if this a S316, then it could be the speed control mounted on the motor, Part # 04416342 and sells for around $83.00. Both of these models are Cat Naad Dog so you need the model number berfore you order a part.
