Electric Water Heaters Maintenance Information

These models contain no components that require regular maintenance, but we do recommend that the owner regularly carries out a simple no-contact visual inspection of the water heater's exterior.

Daily (by owner)

• Ensure that no water leaks are evident around the outside of the water heater or from the installer-supplied plumbing connections.
• Visually inspect the exterior of the water heater for signs of discoloration or physical damage.
  If any water leaks, discoloration or physical damage are found during visual inspection, please shut off the power and water supplies to the water heater and contact your installer or a qualified service person immediately. Do not attempt to remove the front cover yourself!

• Remove and clean the inlet water filter screen, and inspect it for damage.

If no damage is evident, the filter can be reused after cleaning.

If you did find that the water filter screen was physically damaged (or permanently clogged), it must be replaced. A new filter comes as part of the water inlet assembly (part# 8733958121). Do not use the water heater without its water filter screen in place, as damage could be caused to the flow transducer or heating elements!

• Test heating elements for correct resistance.
• Inspect heating elements for limescale build up, and clean if any found.

If the inspections reveal any damaged components, they must be replaced prior to placing the water heater back into operation.
