How to clear blockage

The best way to clear a blockage on a Vax 1700 vacuum cleaner is to turn the machine off and remove the dust canister. Then remove the filter from the dust canister and rinse it in water to remove any debris. After the filter is dry, re-insert it into the dust canister and put the canister back into the machine. Finally, turn the vacuum back on to ensure the blockage has been cleared.

That's called your brush bar.
You're missing something. One of three things is happening-
There's either something caught up/wrapped around the brush bar, causing it not to move, like a long string wrapped around it a multitude of times, a blockage going in, or the filter is in need of being washed.. Dirty filters can cause limited to no function.

Read below and at then the VERY bottom is a link to your manual, which you need to review.

WASHING FILTER:
• Press the 'Filter' button so you can remove the cyclone and clear bin unit.
• Check and wash the filter regularly according to instructions to maintain performance.
• The filter may require more frequent washing if vacuuming fine dust or if used mainly in 'HIGH CONSTANT SUCTION' mode.
• Wash the filter with cold water only. Do not use detergents.
• Do not put the filter in a dishwasher, washing machine, tumble dryer, oven, microwave or near a open flame.
• IMPORTANT: After washing please leave at least 12 hours to dry completely before refitting.
• Place the dry filter into the recess of the handle.
• Fit the base of the handle into the aperture on the base of the cyclone and clear bin unit. Push both halves together until the 'Filter' button engages and locks into place.

LOOKING FOR BLOCKAGES:
• Ensure the appliance is disconnected from the charger before looking for blockages.
• Do not operate while checking for blockages. Failure to do so could result in personal injury.
• Beware of sharp objects when checking for blockages.
• Refit all parts securely before using.
• Clearing blockages is not covered by your guarantee.
• If you cannot clear an obstruction you may need to remove the brush bar. Use a coin to unlock the fastener marked with a padlock. Remove the obstruction, replace the brush bar and secure it by locking the fastener. Ensure it is fixed firmly before operating the appliance.

CLEARING BLOCKAGES - THERMAL CUT-OUT
• This appliance is fitted with an automatically resetting thermal cut-out.
• Large items may block the tools or nozzle. If any part becomes blocked the appliance may overheat and automatically cut-out.
• Leave to cool down for 1-2 hours before checking the filter or for blockages.
• Clear any blockage before restarting.
• Refit all parts of the appliance securely before using.
• Clearing blockages is not covered by your guarantee.

I cleared a blockage at the tip of the tube which I had noticed...it had not heated up or anything, I just noticed it was not picking up well, so I cleared it out. but after I cleaned it out, it would not start again. I don't know how to diagnose the problem since it will not start...could be the wire, or anything. So how do I proceed now?

Good morning,

If you've checked both the bag and the filter, the next step would to check for any clogs.

I will detail what you will need to do below, or you can always reference your Owner's Guide (check: How to Check and Clear Hose Blockages)
http://www.eureka.com/service/manuals/77418_r2.pdf

Step 1: Remove hose from hose retainer on the base and check suction at end of hose - if little or no suction, check dust cup. Empty if needed. If no improvement, proceed to step 2.
(Make sure you turn off the switch and unplug the unit before proceeding to step 2)

Step 2: Remove electrical cord from cord hooks. Disconnect the clear tube by unscrewing the 2 screws, then lift away from cleaner. Check for any obstructions that may be in the tube or hose. Any obstructions can be removed by using a blunt instrument to clear the tube or hose (I will sometimes you a bent hanger or a retractable pointer). Flexing the hose may help loosen the blockage. After clearing blockage, reverse above steps to reassemble unit.

I hope this helps. If so, please give this solution a thumbs up!
Have a good day

This is an indication that there's a blockage in the airflow system. Check the hose, power head tube, and behind tank filter for clogs. For the hose and PN, you can detach the hose and drop a coin in one end. If it doesn't roll out, there's a blockage and it needs cleared. Try using a broom stick to push the clog out from the tank end. Or place PN end of hose to the tank in port and turn on vacuum. This should clear the hose.
For the PN, drop a coin into the hose connection. If it doesn't drop through, there's a clog in the PN tube, probably at either the elbow or behind the brush. You may be able to clear it using longnose pliers to pull needles out from the hose end, or try pushing out with a long, dull object. A wooden spoon or spatula handle will work fine.

There are a handful of places that the mechanism can get blocked. The easiest test is to remove the brush attachment and pull the trigger. If it sprays fine, then the blockage is in the small length of tubing in the brush attachment. The most likely place is in the small plastic piece at the very end of the attachment. You should be able to see the small plastic piece where the tubing ends, this is a common place for a blockage. You can usually use a piece of thin wire to clear the blockage.

try taking a small pipe cleaning brush and gently try pushing it out.

Reassembly of what? the cyclone? the plastic holding tank?

Hi.

Check brush roller is spinning & that belt has not snapped.
Check behind brush roller for blockages, Check clear pipe for rips or splits.
Check clear pipe for blockages.
