Abstract: Sacrificial anode is a useful method of CO／TOsion prevention for the inner of electric water heaters，but this method has its weak point，which is diffcuh to check and find out if the anode has lost effectiveness．So to warn users and protect the inner when anode failed，an electronic appliance was designed for warning and control，based on 555 timer and comparator．The applicance can keep the water header safe．

Key words: electric water heater；sacrificial anode；failure；alarm；control
