Remove the screw holding the handle to the body of the vacuum. Remove the screws to separate the parts of the handle to gain access to the switch.

To replace just the hose unscrew it from the swivel attached to the back of the vacuum. The replace swivel insert screwdrivers into the tabs holding it to the body (from inside the dust compartment) to remove it, the new one snaps into place.

Reset switch is located on the back of the vacuum and close to the back wheels.Press a reset switch a few times and vacuum should start. Check also cord plug . Many times metal prongs are broken at the end of the cord (usually one of them)

Replace the switch

Hi There,

This sounds like the Thermal Switch in your motor tripped. All Riccar vacuum cleaners have a motor reset switch, that will shut the motor down when it gets hot. Usually it's caused by a full bag, clog, or dirty filter.

Try resetting the thermal switch first. If this doesn't work, you may have done some more serious damage to the motor, and it might be a good idea to take it into a local Riccar dealer in your area.

Here's a step by step guide on how to check the reset switch on your Riccar 8850:

To reset the thermal fuse:

1. Unplug the vacuum cleaner
2. Check for problem – over–filled bag, clog in hose, clogged filters, etc.

Remove the vacuum bag, and see if you can visibly see any obstructions, or replace the bag if it's full:



Also inspect the Secondary filter while you have the vacuum bag removed from the machine. If the filter is clogged or dirty, rinse under warm water, and air dry completely before reinstalling it into the vacuum. It's best to wash this filter every 30 days, and replace after 4-5 washings.

Here's a link to the secondary filter on our website if you ever need to purchase one:
Riccar 8800 Series Secondary Filter



Your Riccar 8850 also has a set of exhaust filters that are on the front of the vacuum, near the bottom where the upright body meets the agitator housing. These filters when clogged may also cause the thermal switch to trip. These filters are recommended to be replaced every 6-12 months, and are not recommended to be washed.

Here's a link to 2 sets of the exhaust filters for the Riccar 8850 on our website:

It's also possible that you may have clog in the suction port inside of the agitator housing. Remove the bottom plate from the vacuum, and look for the tube that runs on the left hand side from the tray to the rear of the agitator housing. Make sure that this tube is clear from obstructions:



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)


Using a pencil, paper clip or other pointed object, push the reset button in, you should hear a clicking noise when it resets.

Plug the vacuum cleaner back into the wall, and try turning the vacuum on. It should come right back on. If not, it's best to take your machine into a local Riccar authorized repair facility for further more advanced diagnosing.

The reset button on the Riccar 8955 is located on the back of the vacuum cleaner, at the very bottom, right above the rear wheels. You can push the reset button with a ball point pen or something similar.

Greetings from GoVacuum,

The reset buttons on the Riccar vacuum cleaners are located at the bottom of the vacuum cleaner in the back, underneath of where the wand sits on the vacuum cleaner.

Here's a picture of a Riccar 8925 which replaced your 8850 a few years ago, but the reset switch will be in the same exact location on all Riccar uprights;




Here's a closer look of the reset switch;


I hope that I was able to answer your question. You can avoid the reset switch flipping in the first place by always ensuring that you change the bags frequently and when full, as well as the motor filter that sits underneath of the bag. Also keeping the vacuum from clogging will prevent this.

Greetings from GoVacuum,

Yes, the Riccar 4812 does in deed have a reset switch. Unfortunately some dishonest repair man will tell you at this point that your motor has gone, but 7-10 times it's the reset switch.

If you look down at the base of th vacuum cleaner at the vacuum bottom in the back, right above the rear wheels, you will see a small red button. Take a ball point pen, and while the vacuum is plugged in, go ahead and push the red button or the reset switch. Did the vacuum come on?

If not, it may another simple problem of the cord/ plug going bad.

I hink if it just stopped workint all or a sudden, it's prbably the reset switch.

If it's not, please email me or give me a call and I then diagnose the problem for you.
