I was gone for a month and when I turned on the water there was a leak. It was the steel braided supply line that had been chewed through by a rat (first time I ever had a rat). Then the lights did not come on. So I replaced the supply line and THROUGHLY looked over the electrical cord. The rat had chewed 1 of the 3 electrical lines completely through. And there was a 1ft long plastic hose he had chewed through. So BEFORE YOU START THROWING PARTS AT IT check over everything carefully. It took me a few days as I have a Bosch and they are sensor heavy.
