Purchased my intex pump and sand filter last summer and it has worked great until now. We had a pretty heavy thunderstorm come through and now the reset button on the cord will not reset.( It is unplugged from ext. cord) Not sure if it got wet or had a power surge. I placed the cord in the sun in an attempt to dry it, in case that is what happened but still no reset. Is there anything I can do/check before purchasing a new pump?
