The most common reason a sump pump fails is the float switch getting stuck, often due to debris or a misaligned cord, which prevents the pump from turning on when water levels rise. Clogged intake screens or a jammed impeller from small rocks or sludge can also stop it from working, while power issues like a tripped GFCI outlet or a burned-out motor from frequent cycling are frequent culprits too.
