Hi,
In most cases problems with the circulator pump boil down to two problems.
The most common is air in the lines causing an air lock.
The next problem is that the pump gets stuck and is not running even though itmay be hot and seem to be running. In this cause the pump can sometimes betaken apart, cleaned and it will work, but usually it needs to be replaced.

Here is a tip that I wrote that will explain circulator pump problems in moredetail.

I bought a pump for my fountain 4 months ago, it stopped working


This sounds like you should check your suction pipeing again and with fish be sure to get a screen for it. Then also check the impeller on the pump to be sure nothing inside it. You will need to open the pump to do this. If it has been working their is probally nothing wrong with the pump itself.

Wilo 3speed recirt pump for my wood stove


I wasn't aware that you would put a citculating pump on a tankless water heater, but as long as the arrow goes in the direction of the water flow that is how it needs to be,, putting a circulator on a tankless kind of goes against what it is for, the tankless will never shut off and once it is on how will it ever satisfy itself to shut down?

3 speed Recirculation pump lost middle speed


It sounds like you might have had a power surge and burnt the windings on the medium speed. If it is bothersome, you will need to replace either the motor or the whole pump. (not sure if replacing just the motor is an option.)
