Having problems with your Vacuums ?

I've just installed a hoover central vaccum SH800CA and when i plug the hose in the inlet, it doesn't turn on. It turns on when I turn on the switch on the canister


Answers :

The hose connects to a set of low voltage contacts inside the top of each inlet. The vac wiring is connected by a low voltage circuit to each inlet as well. your hose when plugged in completes the circuit when you turn the hose switch on. For simplicity ,I also use a coin to connect the terminals mentioned below instead of dragging the hose with you.
Reinsert the hose with the tongue or cord at 12 o clock or 6 o'clock position. If the vac does not start, rotate the hose cuff to 3 oclock.This over rides the hose handle switch to test the vac circuit.
if the vac still does not start you have a loss of LV signal in your wiring. You will need to back track to make sure you have continuity from the vac to each inlet.
if you have colored alarm or telephone type wire, it is very easy to break a wire strand while fastening so go back one connection at a time and inspect.
If you have no power to any inlets,your problem will be in the main run of wire from the vac, likely to the first connection. If you have power at only some inlets, your issue will be at one of your wire junctions, either at a pipe intersection or where two wires meet at an inlet, depending on how the system was wired.

The Vaccum is not turning on when i plug the hose into the wall. The hoover system will turn on when i turn the switch on at the base and wont go off till i turn the switch off. But it will not come on automatically when i put the hose in to the wall connections. Many Thanks Linda


You can test this out by taking a small metal spoon and with the bottom side of the spoon insert it into the vac outlet on the wall. you want to touch the two metal pins inside the vac outlet to test if the unit is the problem or the hose is the prob ... Beam Industries Vacuums

Kenmore canister model 116.25513506 wont turn on. when handle switch is turned to floor. vac motor does not turn on. When switch is turned to carpet, floor nozzle works but vac motor does not. I checked fuse, all o.k. checked continuity for plug, o.k. removed wires for bag full switch...motor wont run. I wired motor directly power cord...motor runs. Thinking it must be the circuit board, how do I bypass it or test it?

I have a 3 year old NuTone CV 353W central vac system and recently the switch on the hose handle does not turn the system on from any outlet in the house. I have to plug the hose into the outlet and then turn the unit on from the switch on the cannister. Any help would be greatly appreciated. Thanks


A great way to check if your switch in the hose is bad would be to turn the hose sideways in the inlet. If the unit turns on you most likely need a new switch. ... Broan-NuTone CV450 Central Bagged Central System Vacuum

We have a series e rainbow cleaner. my wife had been using it i turned off and turned the canister up sie down to get the serial number. it would not turn back on.we need a new hose and thats why i was looking for the serial num. it has a rocker switch and the motor will work on low but will not run on the suction side. i have checked the wiring harnesses out as best i could without taken it all apart. im wondering if it may be the switch. it started once and then stopped.


There is one way to verify if it is the switch.It's kind of dangerous though,but not too bad.You need an extra piece of wire,fairly thick.I would use 4 guage myself.Hold it with pliers,just in case it gets hot.Turn the switch on and hold the wire to ... Rainbow Vacuums

I have a Kenmore canister vacuum - model 25614506. Some time ago, I was not able to turn the vacuum off with the on/off switch, but could still use the vacuum. Turned if off/on by pulling the plug.

Hello, I have a Kenmore Progressive Canister Vacuum 116.20912006. It won't turn on. On the hose assembly, the end where the hose swivel is, there are 4 metal pins that plug into the canister. One of the pins looks like it broke off. There are only three pins remaining. I assume there should be four pins as there are four holes. Is this the problem and is it fixable? The vacuum is from 2002 so I am not sure a replacement part is even available and at what price. Thank you. Susan susan.eng@


Hi Susan, if the pin has broken off you can do one of two things, first, would be to find a local vacuum repair shop and take it there for them to look at. they may be able to look at the hose and fix it for you pretty cheaply. what ... Kenmore Progressive 20912 Bagged Canister Vacuum

No suction Just received my refurb. dyson animal bagless. Finally figured out how to get it all together, turned it on and there is no suction coming up thru the beater bar. The hair is just collecting around the bar and not going up into the canister. It appears all the suction is going thru the open red end of the attachment hose, which has a vented cover piece. Am I missing a piece or is there a switch to turn of the attachment suction?


So the red hose isn't connected to a part on the vaccum so like it is connected to the connester but not to an opening just above the beater bar, this is the only idea i can supply you with. good luck, maybe i got lucky and helped you out. ... Dyson DC17 Animal Bagless Upright Cyclonic Vacuum

The last time the vacuum cleaner was used the outlet sparked causing it to smoke when turning on vacuum cleaner. I replaced the outlet and plugged it in and things seemed o.k. Today I turned on the vacuum, it stayed on for a mili second and went off. I checked the switch on the vacuum and it showed voltage coming and going, but would not turn on again. I checked all the wires in the area of the switch all seemed o.k. I thought maybe there might be a short in the cord. When I went to plug

I had the vacuum cleaner question about the canister and the wand/powerhead... the Kenmore Progressive Vacuum canister model 116.25812 and the canister not powering off without unplugging the vacuum. The solution I received that they both run on their own switch so it is normal makes sense. However, is there a power switch on the canister anywhere? The only way for the canister to be turned off is by unplugging it. Any ideas? One would think there would be a switch. I am new to fixya and hope


Hi. On some models, one switch controls all of the power. Your issue, which is no working switch is almost certainly a blown triac on the circuit boar ... Vacuums
