I too have one of the cheapies - but my brother had a Peerless which did a lot of work for a many years until it stopped.
Upon inspection we found some of the electrical 'stuff' that controlled the pump had melted.
Sent Peerless a photo of the parts and they sent back a bunch of parts...
...eventually it turned out there were deeper problems, but a top response from Peerless in my book
