Vacuum cleaner shuts off after short use. What's the reason. Motor seems very hot.

Vacuum cleaners easily overheat and will shut off as a result. The cause may be a bad electric connection, electric cord or accumulation of hair on the roller bar (prevents the bar from spinning, which burns up the motor). It might be a temporary problem or the motor might have burned up. Let it cool down, check all cords and connections carefully and retry it. You can call Bissell 1-800-237-7691 for more help if this doesn't resolve it

The reset button does not have a significant amount of movement in response to pressing to with a paper clip or ball point pen. If the vacuum does not start upon pressing the button, then either the thermal protection circuit is not why the vacuum stopped in the first place or the reason the thermal protection circuit tripped has not been cleared. Quoting from the manual


"Your Riccar vacuum cleaner comes equipped with a Manual Reset Thermal Fuse Protector. This thermal protector is designed to protect your vacuum cleaner from overheating due to a restriction in airflow (i.e. clogged hose, operating the vacuum without a bag). Should this situation occur, the thermal fuse protector will safely shut off the vacuum cleaner to avoid any potential damage. NOTE: To determine it was the thermal fuse protector that turned off your vacuum
cleaner, please refer to the vacuum cleaner's headlight. If the headlight is on while the motor is off, then the thermal fuse protector did safely shut down the motor. If both the headlight and motor are off, then there is some reason other than the thermal protector (i.e. pulled plug) your vacuum is off.
To reset the thermal fuse:
. Unplug the vacuum cleaner

1. Check for problem - over-filled bag, clog in hose, clogged filters, etc.
2. Correct problem
3. Locate "tripped" fuse - the small white button located on the bottom of the back side of the main body (roughly one inch to the right of the left wheel)
4. Using a pencil, paper clip or other pointed object, push the reset button in
5. Plug vacuum cleaner in and resume use"

i think the coil lamination have got shorted or there may be any shorting of circuit. you should get it repaired without anymore use.

The vacuum is probably getting hot and the thermal sensor in the motor is shutting it off and then allowing it to come back on after it cools down. You mentioned replacing the secondary filters, replace the exhaust filter too.
If replacing all the filters did not solve it you may have a clog or restriction somewhere causing the loss of suction and the overheating.

Was it hot when you pressed "+" button? Did you check the filters(Hepa) or bag if clogged or suction path was blocked? Does it happen after it was cool down? From what you said, it seems none of the above. Only thing I can think of is circuit board. The mortor runs in variable speed. "+" increase the average voltage to the motor thus higher suction. PWM circuit in main pcb may not working correctly.

High priced vacuum cleaner like this shouldn't fail like this but it does. JMO.

It sounds like something is catching in the brush. Remove all foreign matter from around brush. Ensure belt is properly engaged. Ensure brush is installed correctly.
If these don't correct the problem, consider taking it to an authorized service center.

There is a short in the vacuum and it appears to be intermittent.

With the cleaner on. move the cable where it enters the cleaner through a rubber grommet. There is a common fault with these cleaners that the cable breaks at that point. soon the cleaner wont work at all until it is rewired.

Greetings from GoVacuum,

The answer to this question is yes, sometimes the filters can cause the vacuum to shut off. This typically happens when the filter behind the bag, or the pre-motor filter is clogged or dirty. Also if you have a clog somewhere in the system, this can also cause the machine to power down after a short usage time.

If the machines shuts down, and won't start until waiting for a period of 1-2 hours, then what's happening is that for some reason the motor is overheating, and to protect the motor from damaging itself because the motor can not breathe, it will shut it self down as a precaution.

This is either caused by a clog in the vacuums hose or power nozzle, or it can also be caused by a full bag, or dirty filter.

If the vacuum will not turn on at all, not even for a short time, this indicates something more serious then a clog or filter, and can be one of a number of things from the cord, or switch, and can also be an electronic circuit board, the motor itself, or the hose to vacuum cleaner may have gone bad.

If you can kindly be a little more specific on the problems that you are having I would love to try and diagnosis this thing to help you figure this out. I always happy to share my knowledge with others.

You may email me if you'd like, or just respond here with a clarification request.

Greetings from GoVacuum.com,

It sounds like you may have a bad thermal switch inside the machine. Most vacuum cleaners have a switch connected to the motor, so if the vacuum cleaner is running hot, it will shut off to prevent any damage to your motor. You did all the right things by checking the bag, making sure the hose was NOT clogged, and replacing HEPA filter.

Most of the time on canister vacuums, the reason is caused by a clog in the hose, or somewhere in the powerhead. If you're sure that there is no clog anywhere, it is going to be the thermal switch on the motor.

Here's a link to the parts schematic for the Bosch upright vacuum. I hope it helps you in determining how to access the thermal switch. A word of warning to you before you try it, this is a very tough vacuum cleaner to work on, you may want to bring it in to a vacuum repair shop, as this is not an easy repair.
