Polaris 280 not moving

[bware]

This pressure side cleaner has been a real workhorse for about 5 years or so
I did tune up on it last spring, replaced b/u valve and check valve and all was well. Just noticed it not moving this morning. Booster pump is running fine but when I disconnected from wall, noticed very weak water flow. What now?
Thanks!

Is there a screen in the wall fitting that may be clogged? On mine (360) there is a screen in pressure regulator of the cleaner's hose where it attaches to wall port.
Any new or unusual sounds from the booster pump?
Lastly, is the main pump and filter working correctly (what is pressure at filter)?

You may have a restrictor disk in the wall fitting that has only about 3/8 of an inch hole that may have something in it. You have to unscrew the fitting from the pool wall to access it. Its either red or blue.

Thanks for the input. No restrictor in pool wall, but what I thought was the booster pump running turned out to just be vibration from the filter pump. Shut everything down and then turned booster on to the old familiar "hum" and no go.
Replaced the pump and back in business
