How to Unstick Your Pool Vac Ultra

Why isn’t your Hayward Pool Vac Ultra pool vacuum skimming across the bottom like it ought to? Maybe there’s something stuck in it. Here’s how to get it unstuck.

First check the pressure on your pool pump. It should be pulling a consistent and considerable amount of water. If it’s not, the Pool Vac is probably not clogged, but your pool filter is.

The heart of the vacuum is a little turbine that rotates with the suction from your pool pump. If something gets stuck in there, the turbine won’t spin, and the Pool Vac will just sit there like a frustratingly lifeless lump on the bottom of your pool.

All you need to accomplish this fix is a Phillips screwdriver.

Pull the vac from the bottom of the pool and drain the water out of it. Disconnect it from the vacuum hose.

Turn it upside down. Stick your finger through the hole in the inlet port cover and see if you can turn the turbine: it’s the black roller-shaped part just inside the hole. If you can turn it, shake the Pool Vac to see if you hear anything loose moving around in there. If not, the problem is more likely with the pool pump pressure than with the Pool Vac.

If the turbine doesn’t turn, or if you hear something rattle inside, we have to dig a little deeper.

Loosen the screw that holds the inlet port cover in place. It’s right in the center of the Pool Vac. You can only loosen it, as it’s attached to the cover. Remove the inlet port cover.

Now remove the (4) screws that hold the chassis in place. There are two kind of hidden under the front flapper. Lift the chassis off of the Pool Vac.

Now you can see the turbine assembly. If something is caught in your Pool Vac, it will either be in the turbine cavity or caught in the wheels and rockers of the chassis. Clear out whatever was stuck.

Use the (4) screws to put the chassis back in place.

Here’s something you may or may not have known, but might save you some frustration: the screws are made from stainless steel, and are therefore not magnetic. It’s a real challenge to get them into the holes under the front flapper, but try this: hold the screw firmly against the end of the screwdriver with the tip of your forefinger, and then push it straight down into the hole.

Reinstall the inlet port cover. Boom. You’re good to go!

Please note: do not do this procedure if you are not certain that you can complete it safely, or if it doesn’t seem accurate. Skippity Whistles provides this information as advice, and cannot accept any liability for your usage of it.
