2020 Hayward Max Flo XL 3/4 : not able to disassemble the turbine

[Liooo80]

Hello !

My pump (installed in 2020, recent) is making a little noise (not permanent). It's a model with variable speed. I tried to open it by removing the four main screws, but I haven't been able to pull the impeller from the pump Strainer Housing. It's just open with 3-4 mm. BTW, it has been efficient, because the noise has disappeared. I think that a debris was the cause of the noise...
Do someone know how to pull out this impeller in case of need (it's blocked, i didn't want to pull strong) ?

There are 4 screws (#13) that hold the motor on to the back plate (#12) and 4 screws (#6) that hold the back plate on to the housing (#4). You want to make sure your are removing the later, not the former.

Thks for your reply. Actually that's exactly what I did by removing the four screws (#6) : But the back plate is only moving of 3-4 mm, even with lifting a little bit the motor while pulling. I tried to gently insert a screwdriver but don't want to break the back plate...

The rubber seal can be stiff so you might try rocking the motor to loosen it.
