No. The only replaceable part of the chlorinator is the electrode. The life of the electrode depends on the quality of the water, how often the pool/hot tub is used and how often the saltwater system (chlorinator) is turned on. The saltwater system (chlorinator) is equipped with an automatic cleaning cycle that extends the life of the electrode. Make sure the self-cleaning program is switched on. Routine maintenance (see manual) will extend its life even further.
