Pondmaster 250: Impeller or motor broke?

I have 2 pondmaster 250s that do not work. The newest one is 3 weeks old. These units were used for the protein skimmer in the filter aquarium (refugium) beneath the big aquarium above. Somtimes the water evaporates and gets dangerously low. This may have happened and the water level was below the pump. I pulled the impeller on the newest one out and it seems to be ok. Did the motor burn up on this unit? Is there a way to tell?
I tried to pull the impeller out of the oldest unit that quit working. The magnetic portion of the impeller seems to be stuck in the the pump. The front portion of the impeller came out.
I will definitely install a float switch to shut the pump off in the future when the water gets too low. It is not that critical to keep this pump running all the time. I don't want to have to buy a new pump everytime the water gets a little low.

Pondmaster 250 comes with a 3 year manufacturer warranty you should just exchange it for a new one. Overheating from low water sounds like the issue but as long as the shaft and housing are not scarred from debris they will replace without any questions

9.5 pump not working after running dry several hours by accident. Will replacing impeller make it work again?

Probably. As long as the motor is obviously turning and operating correctly. A dry impeller will burn up and lose it's seal along the interior of the pump housing.

I have a pondmaster ap40, pump stopes pumping, if you unplug it for an hour and plug it back in it will work for a day or so. Can it be fixed?

Either the motor is going bad or you have an obstruction that is making it work too hard...Check all filters and the impeller to make sure everything is okay...

Pondmaster 1200gph pump stopped working. Inside

Sounds like the impeller broke.

Just remove the 4 phillips head screws to remove the housing, then pull the impeller out. When replacing the impeller be sure to have a good grip on it as the magnetic attraction will pull it in pretty hard.

The pump may still be under warranty, if so call the number on this web page: You can also order parts from them.

My pondmaster pump model 18 will not start back up

Usually when those pumps start doing that the impeller needs to be cleaned. Just remove the impeller housing with a phillips screwdriver and carefully pull out the impeller. I use an aquarium tubing brush to clean the impeller. A bottle brush will work too. Be very careful when you re- insert the impeller back into the housing, as the strong magnetic force will slam it back in if you aren't holding on to it with a good grip. Try to avoid that.
It's also possible that the impeller is going bad and needs replaced (probably about $40 for that pump). Sometimes the bushings wear out too.
Check inside the motor housing for scoring, not good. The only cure for scoring is to replace the pump.
