My S300 only moves a little (a few seconds) and then just sits on the bottom. I pulled the impeller housing/cover to see if any debris was stuck in there. It was clear, but the impeller does not turn by hand or when powered. I bought it from Marina Pool Spa and Patio in July 2018. Since I bought it out of state via the phone (not internet), will the two year warranty cover this repair? Will my local Maytronics dealer handle the repair? Any other advice?
