Just do maintenance as the dirt deposits can slow down rotor spin.

Keeping the product clean is a good rule to guarantee the constance of maximum performances. We recommend an inspection and to perform a cleaning at least every 3 months.

Press the two corners of chamber for 4-5 seconds then release.

This definitely solves the issue.

See pictures below.

There's friction/interference between ceramic bearings and rotor. The operation to do is to pull up the rotor (by maintaining it in its housing) and to move it backward using quite strength with hands. Then repeat the same operation after having manually rotated it half a turn (180°) and after this operation it will be completely free to move axially up and down without "scratching". After this operation, please let the pump go at 100% (or without Waver) possibly at least for 4-6 hours. This should settle definitely the bearings alignment.

Watch the following video tutorial

Manual Rotor Alignment


1- Extract the rotor, ensure you've done an appropriate maintenance and verify that there isn't any dirt deposit which can cause right startup to fail 

2- Verify the integrity of the rubber teeth inside the rotor disc.

Rubber Teeth

If they are compromised, it's required to replace the rotor. 

IMPORTANT: rotor is not included in warranty.

Find the right spare for your Mover. Browse the catalougue -> Spare parts

Check if the rotor bottom end cylinder has not been submitted to an abnormal wear (e.g. saltwater mixing). If it's compromised, it's required to replace it.

Plastic teeth are touching the shock absorber rubber teeth. This situation could be produced by a wrongly positioned rubber shock absorber inside the rotor locking disc. It's enough you follow these instructions to verify if this is the matter:
- unplug the pump and take it out of the water
- unmount the front chamber
- without disassembling the rotor, rotate it manually and try to feel if it rotates freely or if you feel it "touches" something during its rotation.
If you feel this "touches something" during its rotation, then it's enough to unmount the rotor and take a look at its rubber teeth.
They should be both below the end level of plastic cylinder of at least 0,039in ch. Attached you can find a photo for you to verify the correct position.

Rubber Shock Absorber Correct Position


To repair this issue definitely, it's enough to bring the rubber shock absorber in its correct position.
Our suggestion is to use a small - screwdriver (not a +) and press the rubber down all around the circumference.
