Bradford White M-I L6DS electric tanks use universal 4500W screw-in elements. Replacement is a 60-minute DIY at $30-$60.
Symptoms
- Upper element failed: no hot water at all
- Lower element failed: hot then quickly lukewarm
- Both: no hot water + breaker trips (rare)
Part numbers
Bradford White uses standard 4500W 1" NPT screw-in elements. Universal-compatible elements from Camco, Reliance, or Rheem-branded work fine.
Replacement procedure
- Shut off power, verify with voltage meter
- Shut off cold inlet, open hot faucet
- Drain tank to below element location
- Remove access panel, pull aside insulation
- Disconnect element wires
- Unscrew element with 1-1/2" element wrench
- Install new element with fresh gasket, torque ~25 ft-lbs
- Reconnect wires, refill tank, restore power AFTER tank is full
Common mistakes
- Powering up before refilling — destroys new element in seconds
- Reusing gasket — single-use; guarantees a slow leak
- Using regular socket instead of element wrench — rounds the hex
Bottom line
$50 parts + 60 min DIY. For full parts directory see parts hub.
