Bradford White RG250T6N 50 Gallon 40,000 BTU 0.67 EF Defender Safety System Gas Water Heater MECH-DIP-TUBE Error Fix: Broken Dip Tube — Lukewarm Water

Error code MECH-DIP-TUBE on the Bradford White RG250T6N 50 Gallon 40,000 BTU 0.67 EF Defender Safety System Gas Water Heater means: Broken Dip Tube — Lukewarm Water. The dip tube (a plastic tube inside the tank that directs incoming cold water to the bottom) has broken or deteriorated. When the dip tube fails, incoming cold water mixes with hot water at the top of the tank instead of being delivered to the bottom for heating. Symptoms include lukewarm water instead of hot, small white plastic flecks at faucet aerators and showerheads, and short hot water recovery. The dip tube connects to the cold water inlet at the top of the tank. To replace it, shut off the water, disconnect the cold water line, and pull the old dip tube out with pliers. Insert the new dip tube and reconnect. Flush the tank to remove any broken plastic debris.
