Plumping for ejector pump https://imgur.com/gallery/dSrDFlt

I have an ejector pump that handles the washing machine. Shower. Toilet. Sink. And humidity water.

The pump would intermittently fail.. always was able to catch it but scared to do laundry and not even be home.

Plumber first replaced the ejector. It was 10 years old. Same problem occurred though. And now did a weep hole. It lasted longer but still failed at an intermittent time.

They won't cover pump on warranty cause it still works. Any thoughtz?

Edit: So the float kicks the motor on. Can hear the motor go. And sometimes a little water flows (I don't open the cover every time to see water movements but I can hear in the wall if there is). But not really much draining. I catch it with the alarm and do a power toggle and it usually snaps it to back to pumping water out. I have had an electrician check this and it was fine.
