Power turned on at wall & dishwasher makes noise as if operating but no LED lights. Drawer is warm when door opened so element working. After press Power button &/or Start/Pause &/or wash cycle button noise continues but no LED lights appear. Hose connections and taps okay but no water being sprayed by arms & no indication of water in dishwasher. After pouring large pot of water into dishwasher & power turned on at wall, arms spray water around dishwasher, but still no LED lights.
