A few days ago my varible speed pump began running for approximate 15 minutes and then shutting down. The Timeout alarm is displayed in the panel and on my phone application. I have cleaned the filter and baskets and checked that all valves are as they should be. The pump does not appear to be over heating, it is not hot to touch after shut down. I know that my T cell needs to be replaced, could that be the reason the pump is being shut down?
