Pools sweeper

The Kreepy Krawley (however you spell it) works for 5-6 minutes, stops, starts again after backwash, works 5-6 minutes, repeat process. Any suggestions as to what the problem might be and how to fix it?

The curious thing here is the connection to backwashing. Are you saying the only time it works is for 5 mins immediately after backwashing? If so, that would seem to suggest a water flow rate problem. The automatic cleaners need some minimum flow rate to work. It could be you have a clogged filter problem and backwashing gets the flow open enough. But the strange part is that it only lasts 5 mins.

How old is the Kreepy Krauly? After 3-4 years [in Hawaii] they get very tempermental and require just the right suction. If you have a newer unit, contact customer support http://www.pentairpool.com/products/products3.php?id
