In many cases, issues can be caused due to a damaged or a clogged impeller or shaft. Weed or algae can wrap around these parts and restrict it from spinning quick enough, therefore reducing the flow.

Important: Disconnect mains electricity supply before handling or attempting maintenance. Always fully read and check the troubleshooting section within your product instruction manual. 

The impeller 'fan' piece should rotate half way and stop. If it can rotate completely 360 then the impeller is damaged and will need replacing.
