[QUOTE="JMichael, post: 326549, member: 7544"] The impeller doesn't appear to have any broken fins and its not so old and stiff/hard that it's staying curled once it's removed from the pump housing so I don't think it's an impeller issue. I'm thinking along the same lines as Crazymanme2 and would check out the thermostat and look for other obstructions in the water path. If it were me, I'm probably try removing the thermostat completely and testing it like that. If that cures the problem, then you could get a new thermostat. [/QUOTE]
