Topsflo TD5 Not Working

[d40dave]

I have a Topsflo TD5 pump that died today. The power adapter is OK. It makes no sound at all like power bad. Any ideas, thanks.

Mine wouldn't fire up a couple weeks ago. Took it apart and cleaned it and it fired right up.

Been working great since.

Been doing a better job of post brew cleaning since.

Force hot water through it for 2 minutes. If still no start up, take it apart and clean the impeller shaft so the impeller spins freely.

I ended up taking it apart and cleaning it, that fixed it. There was one small washer that I'm not 100% sure where it goes. I'm pretty sure it goes ion the impeller shaft after the impeller. Thanks.

Probably a thrust washer.
Yes, it goes on the end of the shaft, so it ends up between the impeller and the housing.

Thrust washers tend to wear out, and need to be replaced periodically.
Clean and inspect more frequently...

Thanks IslandLizard. I'm not sure where to get a new thrush washer. I will do a better job of cleaning it.

They're usually available from the pump manufacturer. If you have one to measure, or know the right size you can buy a 20-100-pack from 3rd party sellers. Thrust washers are typically made of Teflon (PTFE).

I really wish pumps came with a dozen or so thrust washers when you buy them... a couple dollar's worth of security for a foreseeable future on a $100-200 pump.

It's a stainless thrust washer. I've had the same one in my TD5 for over 5 years.
